Contributors#

  • @dholth

24.1.0 (2024-01-24)#

Special announcement#

The conda_env.* modules have been merged into the conda package!#

To improve the integration of the conda env subcommand (previously standalone), we’ve moved its code into the conda package, while allowing old conda env commands to still work via Python import redirects. This is a first step of many to improving the user experience of the conda command line interface related to environment management. (#13168)

Enhancements#

  • Verify signatures on to-be-installed packages instead of on all packages. (#11545, #13053)

  • Add new pre-solves and post-solves plugin hooks. (#13053)

  • Add support for Python 3.12. (#13072)

  • Check repodata.json.zst for faster repodata downloads. (#13256)

  • Add --skip-flexible-search option in conda search to skip flexible search. (#13315)

  • Provide a more useful warning when attempting to rename a non-existent prefix. (#13387)

  • Add a new flag --keep-env to be used with conda remove --all. It allows users to delete all packages in the environment while retaining the environment itself. (#13419)

  • Add a Y/N prompt warning users that conda env remove and conda remove --all deletes not only the conda packages but the entirety of the specified environment. (#13440)

  • Add --repodata-use-zst/--no-repodata-use-zst flag to control repodata.json.zst check; corresponding repodata_use_zst: true/false for .condarc. Default is to check for repodata.json.zst. Disable if remote returns unparseable repodata.json.zst instead of correct data or 404. (#13504)

Bug fixes#

  • Create the ~/.conda directory before trying to write to the environments.txt file. (#13338)

  • Ensure PackageRecord.timestamp is dumped in milliseconds. (#13483)

  • Fix error when setting a non-default repodata filename via CONDA_REPODATA_FNS. (#13490)

  • Fix the config file location where the integrated Anaconda client gateway loads user configuration from. This is a regression introduced in conda 23.11.0 when the platformdirs library was adopted. (#13517 via #13520)

  • Interpret missing Cache-Control header as max-age=0 instead of exception. (#13522)

23.11.0 (2023-11-30)#

Special announcement#

New menuinst v2 support!

conda has supported Start menu items on Windows for a long time. This is what allows users to open up their Miniconda prompt on CMD (Command Prompt) with an initialized conda session. This menu item (or shortcut) creation logic is provided by the menuinst package.

With the release of 23.11.0, conda now supports menuinst v2, which enables the same experience across Windows, Linux, and macOS. This means package builders will be able to provide desktop icons across all operating systems, which can be especially useful for GUI applications. See the documentation for more details.

If you don’t want conda to create shortcuts, you can disable it via:

  • shortcuts: false entry in your .condarc configuration

  • CONDA_SHORTCUTS=false environment variable

  • --no-shortcuts command-line flag

Enhancements#

  • Add support for menuinst v2, enabling shortcuts across all platforms (Windows, Linux, macOS) using a new JSON schema (see CEP-11). Retain support for old v1-style JSON menus. (#11882)

  • Stop using vendored chardet package by requests/pip; explicitly depend on charset_normalizer. (#13171)

  • Introduce a new plugin hook, CondaHealthCheck, as part of conda doctor. (#13186)

  • Include activate and deactivate in the --help command list. (#13191)

  • Prioritize download of larger packages to prevent smaller ones from waiting. (#13248)

  • Display the used solver in conda info output for debugging purposes. (#13265)

  • Add __conda virtual package. (#13266)

  • Switch from appdirs to platformdirs. (#13306)

  • Implement resume capability for interrupted package downloads. (#8695)

Bug fixes#

  • Log expected JLAP range-request errors at info level, occurring when the remote file has rolled over. (#12913)

  • Fix a bug causing an error when options like --debug are used without specifying a command. (#13232)

  • Improve CTRL-C (cancellation) handling for parallel download threads. (#13234)

  • Allow overriding of CONDA_FETCH_THREADS/fetch_threads to set parallel package downloads beyond the default 5. (#13263)

  • Require requests >=2.28 for enhanced response.json() exception handling. (#13346)

  • Apply callback=reset_context in conda.plan to resolve conda-build + conda-libmamba-solver incompatibilities. (conda-libmamba-solver#393 and conda-libmamba-solver#386 via #13357)

Deprecations#

  • Deprecate conda.plugins.subcommands.doctor.health_checks.display_health_checks function. (#13186)

  • Deprecate conda.plugins.subcommands.doctor.health_checks.display_report_heading function. (#13186)

  • Remove ruamel_yaml fallback; use ruamel.yaml exclusively. (#13218)

  • Deprecate conda.gateways.anaconda_client.EnvAppDirs in favor of platformdirs. (#13306)

  • Mark conda._vendor.cpuinfo for pending deprecation. (#13313)

  • Deprecate conda._vendor.distro in favor of the distro package. (#13317)

Docs#

  • Add the conda-sphinx-theme to the conda documentation. (#13298)

  • Update specific pages to remove redundant TOC entries. (#13298)

  • Include instructions on updating conda in the main README.md. (#13343)

Other#

  • Add a lighter weight s3 test; update embedded test package index. (#13085)

  • Refactor code to use lazy imports for all relative imports in conda.cli.main_*, and separate argparse configuration functions from conda.cli.conda_argparse to their respective conda.cli.main_* modules. (#13173)

  • Move custom argparse.Actions to conda.cli.actions (e.g., NullCountAction), and relocate helper argparse functions to conda.cli.helpers (e.g., add_parser_prefix). (#13173)

  • Update upper bound for ruamel.yaml to <0.19 following the release of 0.18. (#13258)

  • Replace black with ruff format in pre-commit. (#13272)

23.10.0 (2023-10-30)#

✨ Special announcement ✨#

This is an announcement about an important change in conda’s functionality:

With this 23.10.0 release we are changing the default solver of conda to conda-libmamba-solver! 🥳 🚀#

The previously “classic” solver is based on pycosat/Picosat and will remain part of conda for the foreseeable future, a fallback is possible and available.

Why are we switching the solver?#

In short: to make conda faster and more accurate.

A “solver” is the core component of most package managers; it calculates which dependencies (and which version of those dependencies) to install when a user requests to install a package from a package repository. To address growth-related challenges within the conda ecosystem, the conda maintainers, alongside partners Anaconda, Quansight and QuantStack, introduced a new conda dependency solver based on the Mamba project in December 2022.

Since July 2023, the conda-libmamba-solver plugin has been included in all major conda ecosystem installers (miniforge, miniconda, mambaforge and Anaconda Distribution), but was disabled by default. As soon as these installers are updated to contain conda 23.10.0 or later, they will automatically default to using the conda-libmamba-solver plugin.

What can I do if this update doesn’t work for me?#

If the new solver is not working as you expect:

  • Check if the behavior you are observing is a known issue or a deliberate change.

  • If that’s not the case, please consider submitting a bug report or feature request in the conda-libmamba-solver repository.

  • If necessary, you can go back to using the classic solver without modifying your conda installation:

    • When possible, pass the command line option --solver=classic to your conda calls.

    • Otherwise (e.g. for conda build ... or constructor ...), set the environment variable CONDA_SOLVER=classic.

    • For permanent changes, use the conda configuration system: conda config --set solver classic.

Where can I learn more about conda-libmamba-solver?#

The documentation of the conda-libmamba-solver plugin can be found on conda.github.io/conda-libmamba-solver.

For more information about the conda-libmamba-solver rollout plan, please also see our blog post from earlier this year.

Enhancements#

  • Provide --platform and --subdir flags to create environments for non-native platforms, remembering that choice in future operations. (#11505 via #11794)

  • IMPORTANT: Set solver: libmamba as the new default solver. (#12984)

Bug fixes#

  • Check name of symlink, not its target against valid configuration file names (condarc, .condarc, or *.yml/yaml). (#12956)

  • Have conda doctor ignore blank lines in ~/.conda/environments.txt. (#12984)

23.9.0 (2023-09-27)#

Special announcement#

This is an announcement about an important and positive future change in conda’s functionality:

We will change the default solver of conda to conda-libmamba-solver in a special 23.10.0 release in the near future!

You can already benefit from it today by configuring your conda installation to use it (e.g. by running conda config --set solver libmamba).

The current “classic” solver is based on pycosat/Picosat and will remain part of conda for the foreseeable future, a fallback is possible and available (see below).

Plan to change the default solver#

Here is our updated plan to change the default solver, to better follow CEP 8 and reduce the potential impact on conda users:

  • The upcoming, special 23.10.0 release will be dedicated to the switch of the default solver to libmamba.

  • Users will be able to opt out of the libmamba solver and use the classic solver instead, by using one of these options:

    • the --solver=classic command line option,

    • the CONDA_SOLVER=classic environment variable or

    • running conda config --set solver classic.

  • All development of conda-libmamba-solver plugin happens in the conda-libmamba-solver repo, including issue tracking.

  • The documentation of the conda-libmamba-solver plugin can be found on conda.github.io/conda-libmamba-solver.

For more information about the conda-libmamba-solver rollout plan, please also see our blog post from earlier this year.

Context#

A “solver” is the core component of most package managers; it calculates which dependencies (and which version of those dependencies) to install when a user requests to install a package from a package repository. To address growth-related challenges within the conda ecosystem, the conda maintainers, alongside partners Anaconda, Quansight and QuantStack, introduced a new conda dependency solver based on the Mamba project in December 2022.

Since July 2023, that conda-libmamba-solver plugin has been included in and automatically installed with all major conda ecosystem installers (miniforge, miniconda, mambaforge and Anaconda Distribution), with the default solver configuration unchanged.

Enhancements#

  • Improve speed of fish shell initialization. (#12811)

  • Directly suppress use of binstar (conda) token when fetching trust metadata. (#12889)

  • Add a new “auth handler” plugin hook for conda. (#12911)

  • Lock index cache metadata by default. Added --no-lock option in case of problems, should not be necessary. Older --experimental=lock no longer has an effect. (#12920)

  • Add context.register_envs option to control whether to register environments in ~/.conda/environments.txt when they are created. Defaults to true. (#12924)

  • Inject a new detailed output verbosity level (i.e., the old debug level -vv is now -vvv). (#12985, #12977, #12420, #13036)

  • Add support for truststore to the ssl_verify config option, enabling conda to use the operating system certificate store (requires Python 3.10 or later). (#13075 and #13149)

  • Add emscripten-wasm32 and wasi-wasm32 platforms to known platforms. (#13095)

  • Adds the py.typed marker file to the conda package for compliance with PEP-561. (#13107)

  • Import boto3 only when S3 channels are used, saving startup time. (#12914)

  • Treat JSONDecodeError on repodata.info.json as a warning, equivalent to a missing repodata.info.json. (#13056)

  • Fix sorting error for conda config --show-sources --json. (#13076)

  • Catch OSError in find_commands to account for incorrect PATH entries on Windows. (#13125)

  • Catch a NotWritableError when trying to find the first writable package cache dir. (#9609)

  • Apply minimal fixes to deal with these (and similar) crashes. (#12014)

  • Prevent conda from using /bin/sh + exec trick for its own entry point, which drops $PS1 on some shells (#11885, #11893 via #12043).

  • Handle CTRL+C during package downloading more gracefully. (#12056)

  • Prefer the outer name when a MatchSpec specifies a package’s name twice package-name[name=package-name] (#12062)

22.9.0 (2022-09-14)#

Special announcement#

If you have been following the conda project previously, you will notice a change in our version number for this release. We have officially switched to the CalVer versioning system as agreed upon in CEP 8 (Conda Enhancement Proposal).

Please read that CEP for more information, but here is a quick synopsis. We hope that this versioning system and our release schedule will help make our releases more predictable and transparent to the community going forward. We are now committed to making at least one release every two months, but keep in mind that we can (and most likely will) be making minor version releases within this window.

4.12.0 (2022-03-08)#

Enhancements#

  • Add support for libmamba integrations. (#11193)

    This is a new experimental and opt-in feature that allows use of the new conda-libmamba-solver for an improved user experience, based on the libmamba community project - the library version of the mamba package manager.

    Please follow these steps to try out the new libmamba solver integration:

    1. Make sure you have conda-libmamba-solver installed in your conda base environment.

    2. Try out the solver using the --experimental-solver=libmamba command line option.

      E.g. with a dry-run to install the scipy package:

      conda create -n demo scipy --dry-run --experimental-solver=libmamba
      

      Or install in an activated conda environment:

      conda activate my-environment
      conda install scipy --experimental-solver=libmamba
      
  • Make sure that conda env update -f sets env vars from the referenced yaml file. (#10652)

  • Simplify the Linux GitHub actions workflows by combining used shell scripts.

  • Add periodic GitHub Actions workflow to review old issues in the conda issue tracker and mark them as stale if no feedback is provided in a sensible amount of time, eventually closing them.

  • Add periodic GitHub Actions workflow to lock the comment threads of old issues and pull requests in the conda GitHub repository to surface regressions with new issues instead.

  • Refactor test suite to use more GitHub Actions runners in parallel, reducing total run time by 50%.

  • Switched the issue tracker to use forms with additional questions for bug reporters to help in ticket triage.

  • Add and automatically run pre-commit as part of the CI system to improve the code quality continuously and raise issues in contributed patches early on.

    The used code linters are: flake8, pylint and bandit.

    The Python code formatter black is used as well but is only enforced on changed code in a commit and not to the whole code base at once.

  • Automatically build the conda package upon the successful merge into the master branch and upload it to the conda-canary channel on anaconda.org.

    To try conda out simply run:

    conda install -c conda-canary/label/dev conda
    
  • Automate adding new issues to public GitHub project board to facilitate issue triage.

  • Update GitHub issue and pull request labels to be more consistent.

  • Start using rever for release management.

  • (preview) Enable one-click gitpod and GitHub Codespaces setup for Linux development.

4.7.2 (2019-06-10)#

Behavior changes#

  • unsatisfiability is determined in a slightly different way now. It no longer uses the SAT solver, but rather determines whether any specs have no candidates at all after running through get_reduced_index. This has been faster in benchmarks, but we welcome further data from your use cases about whether this was a good change. (#8741)

  • when using the --only-deps flag for the install command, conda now explicitly records those specs in your history. This primarily serves to reduce conda accidentally removing packages that you have actually requested. (#8766)

Improvements#

  • UnsatisfiableError messages are now grouped into categories and explained a bit better. (#8741)

  • –repodata-fn argument can be passed multiple times to have more fallback paths. repodata_fns conda config setting does the same thing, but saves you from needing to do it for every command invocation. (#8741)

Bug fixes#

  • fix channel flip-flopping that was happening when adding a channel other than earlier ones (#8741)

  • refactor flow control for multiple repodata files to not use exceptions (#8741)

  • force conda to use only old .tar.bz2 files if conda-build <3.18.3 is installed. Conda-build breaks when inspecting file contents, and this is fixed in conda-build 3.18.3 (#8741)

  • use --force when using rsync to improve behavior with folders that may exist in the destination somehow. (#8750)

  • handle EPERM errors when renaming, because MacOS lets you remove or create files, but not rename them. Thanks Apple. (#8755)

  • fix conda removing packages installed via install with --only-deps flag when either update or remove commands are run. See behavior changes above. (#8766)

4.7.1 (2019-05-30)#

Improvements#

  • Base initial solver specs map on explicitly requested specs (new and historic) (#8689)

  • Improve anonymization of automatic error reporting (#8715)

  • Add option to keep using .tar.bz2 files, in case new .conda isn’t working for whatever reason (#8723)

Bug fixes#

  • fix parsing hyphenated PyPI specs (change hyphens in versions to .) (#8688)

  • fix PrefixRecord creation when file inputs are .conda files (#8689)

  • fix PrefixRecord creation for pip-installed packages (#8689)

  • fix progress bar stopping at 75% (no extract progress with new libarchive) (#8689)

  • preserve pre-4.7 download() interface in conda.exports (#8698)

  • virtual packages (such as cuda) are represented by leading double underscores by convention, to avoid confusion with existing single underscore packages that serve other purposes (#8738)

Deprecations/Breaking Changes#

  • The --prune flag no longer does anything. Pruning is implicitly the standard behavior now as a result of the initial solver specs coming from explicitly requested specs. Conda will remove packages that are not explicitly requested and are not required directly or indirectly by any explicitly installed package.

Docs improvements#

  • Document removal of the free channel from defaults (#8682)

  • Add reference to conda config --describe (#8712)

New Feature Highlights#

  • A new flag, ‘–envs’, has been added to ‘conda search’. In this mode, ‘conda search’ will look for the package query in existing conda environments on your system. If ran as UID 0 (i.e. root) on unix systems or as an Administrator user on Windows, all known conda environments for all users on the system will be searched. For example, ‘conda search --envs openssl’ will show the openssl version and environment location for all conda-installed openssl packages.

4.4.0 (2017-12-20)#

New Feature Highlights#

  • conda activate: The logic and mechanisms underlying environment activation have been reworked. With conda 4.4, conda activate and conda deactivate are now the preferred commands for activating and deactivating environments. You’ll find they are much more snappy than the source activate and source deactivate commands from previous conda versions. The conda activate command also has advantages of (1) being universal across all OSes, shells, and platforms, and (2) not having path collisions with scripts from other packages like python virtualenv’s activate script.

  • constrained, optional dependencies: Conda now allows a package to constrain versions of other packages installed alongside it, even if those constrained packages are not themselves hard dependencies for that package. In other words, it lets a package specify that, if another package ends up being installed into an environment, it must at least conform to a certain version specification. In effect, constrained dependencies are a type of “reverse” dependency. It gives a tool to a parent package to exclude other packages from an environment that might otherwise want to depend on it.

    Constrained optional dependencies are supported starting with conda-build 3.0 (via [conda/conda-build#2001[(conda/conda-build#2001)). A new run_constrained keyword, which takes a list of package specs similar to the run keyword, is recognized under the requirements section of meta.yaml. For backward compatibility with versions of conda older than 4.4, a requirement may be listed in both the run and the run_constrained section. In that case older versions of conda will see the package as a hard dependency, while conda 4.4 will understand that the package is meant to be optional.

    Optional, constrained dependencies end up in repodata.json under a constrains keyword, parallel to the depends keyword for a package’s hard dependencies.

  • enhanced package query language: Conda has a built-in query language for searching for and matching packages, what we often refer to as MatchSpec. The MatchSpec is what users input on the command line when they specify packages for create, install, update, and remove operations. With this release, MatchSpec (rather than a regex) becomes the default input for conda search. We have also substantially enhanced our MatchSpec query language.

    For example,

    conda install conda-forge::python
    

    is now a valid command, which specifies that regardless of the active list of channel priorities, the python package itself should come from the conda-forge channel. As before, the difference between python=3.5 and python==3.5 is that the first contains a “fuzzy” version while the second contains an exact version. The fuzzy spec will match all python packages with versions >=3.5 and <3.6. The exact spec will match only python packages with version 3.5, 3.5.0, 3.5.0.0, etc. The canonical string form for a MatchSpec is thus

    (channel::)name(version(build_string))
    

    which should feel natural to experienced conda users. Specifications however are often necessarily more complicated than this simple form can support, and for these situations we’ve extended the specification to include an optional square bracket [] component containing comma-separated key-value pairs to allow matching on most any field contained in a package’s metadata. Take, for example,

    conda search 'conda-forge/linux-64::*[md5=e42a03f799131d5af4196ce31a1084a7]' --info
    

    which results in information for the single package

    cytoolz 0.8.2 py35_0
    --------------------
    file name   : cytoolz-0.8.2-py35_0.tar.bz2
    name        : cytoolz
    version     : 0.8.2
    build string: py35_0
    build number: 0
    size        : 1.1 MB
    arch        : x86_64
    platform    : Platform.linux
    license     : BSD 3-Clause
    subdir      : linux-64
    url         : https://conda.anaconda.org/conda-forge/linux-64/cytoolz-0.8.2-py35_0.tar.bz2
    md5         : e42a03f799131d5af4196ce31a1084a7
    dependencies:
      - python 3.5*
      - toolz >=0.8.0
    

    The square bracket notation can also be used for any field that we match on outside the package name, and will override information given in the “simple form” position. To give a contrived example, python==3.5[version='>=2.7,<2.8'] will match 2.7.* versions and not 3.5.

  • environments track user-requested state: Building on our enhanced MatchSpec query language, conda environments now also track and differentiate (a) packages added to an environment because of an explicit user request from (b) packages brought into an environment to satisfy dependencies. For example, executing

    conda install conda-forge::scikit-learn
    

    will confine all future changes to the scikit-learn package in the environment to the conda-forge channel, until the spec is changed again. A subsequent command conda install scikit-learn=0.18 would drop the conda-forge channel restriction from the package. And in this case, scikit-learn is the only user-defined spec, so the solver chooses dependencies from all configured channels and all available versions.

  • errors posted to core maintainers: In previous versions of conda, unexpected errors resulted in a request for users to consider posting the error as a new issue on conda’s github issue tracker. In conda 4.4, we’ve implemented a system for users to opt-in to sending that same error report via an HTTP POST request directly to the core maintainers.

    When an unexpected error is encountered, users are prompted with the error report followed by a [y/N] input. Users can elect to send the report, with ‘no’ being the default response. Users can also permanently opt-in or opt-out, thereby skipping the prompt altogether, using the boolean report_errors configuration parameter.

  • various UI improvements: To push through some of the big leaps with transactions in conda 4.3, we accepted some regressions on progress bars and other user interface features. All of those indicators of progress, and more, have been brought back and further improved.

  • aggressive updates: Conda now supports an aggressive_update_packages configuration parameter that holds a sequence of MatchSpec strings, in addition to the pinned_packages configuration parameter. Currently, the default value contains the packages ca-certificates, certifi, and openssl. When manipulating configuration with the conda config command, use of the --system and --env flags will be especially helpful here. For example,

    conda config --add aggressive_update_packages defaults::pyopenssl --system
    

    would ensure that, system-wide, solves on all environments enforce using the latest version of pyopenssl from the defaults channel.

    conda config --add pinned_packages python=2.7 --env
    

    would lock all solves for the current active environment to python versions matching 2.7.*.

  • other configuration improvements: In addition to conda config --describe, which shows detailed descriptions and default values for all available configuration parameters, we have a new conda config --write-default command. This new command simply writes the contents of conda config --describe to a condarc file, which is a great starter template. Without additional arguments, the command will write to the .condarc file in the user’s home directory. The command also works with the --system, --env, and --file flags to write the contents to alternate locations.

    Conda exposes a tremendous amount of flexibility via configuration. For more information, The Conda Configuration Engine for Power Users blog post is a good resource.

4.3.0 (2016-12-14) Safety#

New Features#

  • Unlink and Link Packages in a Single Transaction: In the past, conda hasn’t always been safe and defensive with its disk-mutating actions. It has gleefully clobbered existing files, and mid-operation failures leave environments completely broken. In some of the most severe examples, conda can appear to “uninstall itself.” With this release, the unlinking and linking of packages for an executed command is done in a single transaction. If a failure occurs for any reason while conda is mutating files on disk, the environment will be returned its previous state. While we’ve implemented some pre-transaction checks (verifying package integrity for example), it’s impossible to anticipate every failure mechanism. In some circumstances, OS file permissions cannot be fully known until an operation is attempted and fails. And conda itself is not without bugs. Moving forward, unforeseeable failures won’t be catastrophic. (#3833, #4030)

  • Progressive Fetch and Extract Transactions: Like package unlinking and linking, the download and extract phases of package handling have also been given transaction-like behavior. The distinction is the rollback on error is limited to a single package. Rather than rolling back the download and extract operation for all packages, the single-package rollback prevents the need for having to re-download every package if an error is encountered. (#4021, #4030)

  • Generic- and Python-Type Noarch/Universal Packages: Along with conda-build 2.1.0, a noarch/universal type for python packages is officially supported. These are much like universal python wheels. Files in a python noarch package are linked into a prefix just like any other conda package, with the following additional features

    1. conda maps the site-packages directory to the correct location for the python version in the environment,

    2. conda maps the python-scripts directory to either \(PREFIX/bin or \)PREFIX/Scripts depending on platform,

    3. conda creates the python entry points specified in the conda-build recipe, and

    4. conda compiles pyc files at install time when prefix write permissions are guaranteed.

    Python noarch packages must be “fully universal.” They cannot have OS- or python version-specific dependencies. They cannot have OS- or python version-specific “scripts” files. If these features are needed, traditional conda packages must be used. (#3712)

  • Multi-User Package Caches: While the on-disk package cache structure has been preserved, the core logic implementing package cache handling has had a complete overhaul. Writable and read-only package caches are fully supported. (#4021)

  • Python API Module: An oft requested feature is the ability to use conda as a python library, obviating the need to “shell out” to another python process. Conda 4.3 includes a conda.cli.python_api module that facilitates this use case. While we maintain the user-facing command-line interface, conda commands can be executed in-process. There is also a conda.exports module to facilitate longer-term usage of conda as a library across conda conda releases. However, conda’s python code is considered internal and private, subject to change at any time across releases. At the moment, conda will not install itself into environments other than its original install environment. (#4028)

  • Remove All Locks: Locking has never been fully effective in conda, and it often created a false sense of security. In this release, multi-user package cache support has been implemented for improved safety by hard-linking packages in read-only caches to the user’s primary user package cache. Still, users are cautioned that undefined behavior can result when conda is running in multiple process and operating on the same package caches and/or environments. (#3862)

Deprecations/Breaking Changes#

  • Conda will refuse to clobber existing files that are not within the unlink instructions of the transaction. At the risk of being user-hostile, it’s a step forward for conda. We do anticipate some growing pains. For example, conda will not clobber packages that have been installed with pip (or any other package manager). In other instances, conda packages that contain overlapping file paths but are from different package families will not install at the same time. The --force command line flag is the escape hatch. Using --force will let your operation proceed, but also makes clear that you want conda to do something it considers unsafe.

  • Conda signed packages have been removed in 4.3. Vulnerabilities existed. An illusion of security is worse than not having the feature at all. We will be incorporating The Update Framework into conda in a future feature release. (#4064)

  • Conda 4.4 will drop support for older versions of conda-build.

4.2.0 (2016-07-28) Configuration#

New Features#

  • New Configuration Engine: Configuration and “operating context” are the foundation of conda’s functionality. Conda now has the ability to pull configuration information from a multitude of on-disk locations, including .d directories and a .condarc file within a conda environment), along with full CONDA_ environment variable support. Helpful validation errors are given for improperly-specified configuration. Full documentation updates pending. (#2537, #3160, #3178)

  • New Exception Handling Engine: Previous releases followed a pattern of premature exiting (with hard calls to sys.exit() when exceptional circumstances were encountered. This release replaces over 100 sys.exit calls with python exceptions. For conda developers, this will result in tests that are easier to write. For developers using conda, this is a first step on a long path toward conda being directly importable. For conda users, this will eventually result in more helpful and descriptive errors messages. (#2899, #2993, #3016, #3152, #3045)

  • Empty Environments: Conda can now create “empty” environments when no initial packages are specified, alleviating a common source of confusion. (#3072, #3174)

  • Conda in Private Env: Conda can now be configured to live within its own private environment. While it’s not yet default behavior, this represents a first step toward separating the root environment into a “conda private” environment and a “user default” environment. (#3068)

  • Regex Version Specification: Regular expressions are now valid version specifiers. For example, ^1\.[5-8]\.1$|2.2. (#2933)

  • print which file leads to the “unable to remove file” error on Windows

  • add support for the no_proxy environment variable, #1171

  • add a much faster hint generation for unsatisfiable packages, which is now always enabled (previously it would not run if there were more than ten specs). The new hint only gives one set of conflicting packages, rather than all sets, so multiple passes may be necessary to fix such issues

  • conda extensions that import conda should use conda.cli.conda_argparser.ArgumentParser instead of argparse.ArgumentParser to conform to the conda help guidelines (e.g., all help messages should be capitalized with periods, and the options should be preceded by “Options:” for the sake of help2man).

  • add --alt-hint as a method to get an alternate form of a hint for unsatisfiable packages

  • add conda package --ls-files to list files in a package

  • add ability to pin specs in an environment. To pin a spec, add a file called pinned to the environment’s conda-meta directory with the specs to pin. Pinned specs are always kept installed, unless the --no-pin flag is used.

  • add ability to disable self update of conda, by setting “self_update: False” in .condarc

  • Try installing packages using the old way of just installing the maximum versions of things first. This provides a major speedup of solving the package specifications in the cases where this scheme works.

  • Don’t include python=3.3 in the specs automatically for the Python 3 version of conda. This allows you to do “conda create -n env package” for a package that only has a Python 2 version without specifying “python=2”. This change has no effect in Python 2.

  • Automatically put symlinks to conda, activate, and deactivate in each environment on Unix.

  • On Unix, activate and deactivate now remove the root environment from the PATH. This should prevent “bleed through” issues with commands not installed in the activated environment but that are installed in the root environment. If you have “setup.py develop” installed conda on Unix, you should run this command again, as the activate and deactivate scripts have changed.

  • Begin work to support Python 3.4.

3.2.0a1 (2014-03-07)#

  • conda now uses pseudo-boolean constraints in the SAT solver. This allows it to search for all versions at once, rather than only the latest (issue #491).

  • Conda contains a brand new logic submodule for converting pseudo-boolean constraints into SAT clauses.
