CHANGELOG

3.5.0 (2025-08-27)

  • Correctly handle parsing envs directories in new mamba versions, where that value was renamed from envs_dirs.

  • Added the ability to generate aarch64 and arm64 locks.

3.4.0 (2024-07-22)

  • Previously the name, channels, and platforms keys would only be overwritten by the root devenv.yml file (the one use to invoke conda devenv with). Now any downstream devenv.yml file will override these keys, with the most downstream devenv.yml file “winning”, which was always the intended behavior.

3.3.0 (2024-02-21)

  • Dependency order is no longer sorted automatically, instead the order is preserved as they are defined in the *.devenv.yml files. Usually this would not matter, but it is important for pip dependencies which declare development installations, as it is important that those happen in the specified order.

3.2.1 (2024-01-03)

  • Fixed handling of constraints when processing lock files and dependencies include a pip section.

3.2.0 (2023-07-11)

  • The CONDA_DEVENV_USE_LOCKS can be used to change the default value of --use-locks. Useful to set on CI to ensure lock files are being used.

3.1.1 (2023-07-04)

  • Fixed bug where the platform selectors of included devenv.yml files were not being honored when rendering lock files.

3.1.0 (2023-06-30)

  • Added support for version constraints in devenv.yml files. Consult the docs.

  • Improved message with --use-locks=yes and no lock files are found.

  • Force flush calls when reporting progress updates, which improves seeing these updates on CI.

3.0.0 (2023-06-19)

  • New workflow to work with lock files, using conda-lock. Consult the docs.

  • Added full type annotations. Some of the parameters were changed from str to Path to make the API more clearer.

  • Python 3.7, 3.8, and 3.9 are no longer supported. Note that conda-devenv installed in a Python 3.10+ conda root can still be used to work with environments in those versions.

  • Dropped an internal hack that attempted to circumvent bugs in conda’s --prune implementation by truncating the install history file: we suspect this is no longer needed and might cause more harm than good.

2.4.0 (2023-03-29)

  • Added aarch64 and arm64 selectors (#166).

  • Fixed bug when an empty environment: key is declared in the ``environment.devenv.yml``file (#164).

2.3.0 (2022-03-07)

  • Now it is possible to use mamba with conda-devenv (#134): - Pass --env-manager in the command-line. - Set the CONDA_DEVENV_ENV_MANAGER=mamba environment variable.

2.2.0 (2022-01-31)

  • Add support for mamba (#110).

2.1.1 (2020-08-13)

  • Correctly handle editable installs when using pip dependencies (#113).

2.1.0 (2020-06-26)

  • New get_env function to handle environment variables in Jinja contexts so it conveys better error messages in case of missing/invalid environment variables.

2.0.0 (2020-06-08)

  • Drop support for Python 2.7, 3.4, and 3.5.

  • Correctly parse relative includes without jinja root.

  • New --verbose flag which is passed on to conda.

1.1.3 (2019-12-26)

  • Accept package version specifiers containing upper case letters (#95).

1.1.2 (2019-05-07)

  • Correctly support git and mercurial repositories in pip dependencies (#92).

1.1.1 (2019-03-22)

  • Remove yaml load warnings by using yaml.safe_load instead of yaml.load.

  • Fix NoneType object is not iterable error when includes is empty.

1.1.0 (2019-02-14)

  • New is_included jinja variable which is a boolean indicating if the current file was included by another devenv.yml file (True) or it is the original file passed to conda devenv (False) (#72).

  • Added shortcuts to common jinja 2 checks, for example win which is equal to sys.platform.startswith("win") (#75).

  • Added support conda-build-style YAML line comments (`` # [win]``) (#79).

  • New min_conda_devenv_version jinja2 function that can be used to specify a minimum conda-devenv version:

    {{ min_conda_devenv_version("1.1") }}
name: my-environment

    This is recommended when using new features so users will be shown a descriptive error message instead of subtle failures (#81).

1.0.4 (2018-09-20)

  • Do not fail if history file does not exists (#66).

  • Obtain envs_dir without using a subprocess (#67).

1.0.3 (2018-06-20)

  • Find correct env directory through envs_dir instead of matching first in envs. This makes environment directory location more reliable in newer conda versions.

1.0.2 (2018-06-07)

  • Fix problem with channel specification being wrongly exported (#62).

1.0.1 (2018-06-04)

  • Truncate the environment’s history file to have the old “prune” behavior when needed (#59).

1.0.0 (2017-09-19)

  • Add –version flag (#47).

  • Provide a better error message when ‘environment.devenv.yml’ file is not found (#48).

  • Support for pip on dependencies section (#55).

0.9.6 (2017-07-24)

  • Applies an “AND” when merging dependencies (#53).

  • On Mac generates the same scripts as for Linux (no longer .bat files).

0.9.5 (2017-04-24)

  • Handle None correctly, which actually fixes (#49).

0.9.4 (2017-04-20)

  • Fixed major bug where activate/deactivate scripts were not being generated (#49).

0.9.3 (2017-04-10)

  • conda-devenv no longer requires conda to be on PATH to work (#45).

0.9.2 (2017-03-27)

  • Fix conda-forge package.

0.9.1 (2017-03-22)

  • Fix activate and deactivate bash scripts: variables not in the environment before activation are now properly unset after deactivation.

  • Fix activate and deactivate bash scripts: quote variables when exporting them.

0.9.0 (2017-03-17)

  • New option --print-full, which also prints the expanded environment: section.

0.8.1 (2017-03-16)

  • Fix entry point call to main.

0.8.0 (2017-03-16)

  • conda-devenv now can receive standard environment.yml files, in which case the file will just be forwarded to conda env update normally.
