| --- | ||
|
|
||
| The September 2024 releases included updates to conda, conda-build, and conda-libmamba-solver! 🎉 All of these have been released to both `main` and `conda-forge` channels. | ||
|
|
||
| ## Changes in Conda [24.9.0](https://github.com/conda/conda/releases/tag/24.9.0)/[24.9.1](https://github.com/conda/conda/releases/tag/24.9.1) | ||
|
|
||
| To update conda, run: | ||
|
|
||
| ```bash | ||
| conda install -n base conda=24.9.1 | ||
| ``` | ||
|
|
||
|
|
||
| ### ✨ Special announcement ✨ | ||
|
|
||
| This is an announcement about an important and positive **future** change in conda's functionality: | ||
|
|
||
| Following feedback from conda users about the pre-configuration of the conda code base to favor channels from Anaconda Inc, we've [started the process to deprecate](https://github.com/conda/conda/issues/14178) hardcoding Anaconda's channels as the default set of channels in the conda source code, which is a remnant of conda's incubation at the company. | ||
|
|
||
| In the future, we will rely on providers of conda distributions, such as [miniforge](https://github.com/conda-forge/miniforge) or Anaconda (including miniconda), to pre-configure their preferred channels, e.g. by running the necessary ``conda config --set channels`` command. | ||
|
|
||
| We're also going to continue to [work on improving channel management](https://github.com/conda/conda/issues/14217) in the foreseeable future and would love to get your feedback. | ||
|
|
||
| <!-- truncate --> | ||
|
|
||
| ### ✨ What's New? ✨ | ||
|
|
||
| - Add `conda.core.index.Index` as a faster drop-in replacement of the realized dictionary index. Note: The loggers are no longer implicitly initialized when fetching the index. Instead, you must explicitly call `conda.gateways.logging.initialize_logging`. | ||
| - Alias `conda env remove` command to `conda remove --all`. | ||
| - Add a new health check to `conda doctor` that detects if the `REQUESTS_CA_BUNDLE` env var points to a non-existent file. | ||
| - Add `--sha256` flag to `conda list --explicit` so it lists URLs with a SHA256 hash instead of MD5 and make `conda install|create` compatible with these inputs. | ||
| - Report `conda` version used to generate a `@EXPLICIT` text file. | ||
| - Update health checks outputs for consistency. | ||
| - Fix Windows to Unix path conversion to handle UNC mounts and root paths. | ||
| - Add a new `denylist_channels` config option and `CONDA_DENYLIST_CHANNELS` environment variable to explicitly deny using specific channels globally, which is complementing the already existing `allowlist_channels` config option. | ||
| - Add `conda commands` subcommand. | ||
| - Add `conda.testing.fixtures.session_capsys`. Use this to capture stdout and stderr within module, package, and session scoped fixtures. | ||
| - Add `conda.testing.fixtures.session_conda_cli`. Use this to invoke conda commands within module, package, and session scoped fixtures. | ||
| - Add `conda.testing.fixtures.session_tmp_env`. Use this to create a conda environment within module, package, and session scoped fixtures. | ||
|
|
||
| ### 🔧 What Got Fixed? 🔧 | ||
|
|
||
| - Prevent directories that contain conda environments from being specified as an environment prefix when creating new envs; this provides guardrails against the accidental deletion of environments via commands such as `conda rename`. | ||
| - Enable `conda doctor` to check whether the environment exists or not before trying to generate a health report. | ||
| - Fix `conda.common.configuration.ObjectParameter`'s ability to appropriately handle defaults. | ||
| - `conda remove [env] --all` command no longer deletes empty parent directories for environments that are removed. | ||
| - Raise an error when attempting to remove non-existent environment. | ||
| - Add pre-/post-command hooks to activation subcommands (`activate`, `deactivate`, `reactivate`, `hooks`, and `commands`). | ||
| - Replace extensions from end of filename only, not `str.replace()`, in two places. | ||
| - Fix PowerShell activation/deactivation to properly unset environment variables using `$Env:VARIABLE = $null` instead of `$Env:VARIABLE = ""`. | ||
| - (24.9.1) Tweak pending deprecation warning for the upcoming changes in channel defaults. | ||
|

| - `conda config --add/--append channels ...` will warn when `defaults` is implicitly added.

Conda distribution installers like miniforge or miniconda will pre-configure conda channels during installation. | ||
| - Without an explicit `channels` configuration (via `condarc` files, environment variables, or CLI flags), conda will warn about using `defaults` implicitly. In 25.3, an empty list will be used. | ||
| - Mark the `restore_free_channel` configuration option as pending deprecation. Add `https://repo.anaconda.com/pkgs/free` to your channel list after `defaults` instead. | ||

| - (24.9.1) Remove deprecated testing entrypoint `shell/bin/conda`. Use `dev/start[.bat]` instead. | ||
|
|
||
| ### 📄 What's New in Documentation? 📄 | ||
|
|
||
| - Document `--platform` flag for `conda [env] create`. | ||
|
|
||
| ### Other | ||
|
|
||
| - Update `xonsh` support to accommodate deprecated import path. | ||
|
|
||
|
|
||
| ## Changes in Conda-Build [24.9.0](https://github.com/conda/conda-build/releases/tag/24.9.0) | ||
|
|
||
| To update conda-build, run: | ||
|
|
||
| ```bash | ||
| conda install -n base conda-build=24.9.0 | ||
| ``` | ||
|
|
||
| ### ✨ What's New? ✨ | ||
|
|
||
| - Reduce render time when there is a large number of unused variants. | ||
|
|
||
| ### 🔧 What Got Fixed? 🔧 | ||
|
|
||
| - Ensure variables mentioned in `script_env` are undefined in the multi-output build environment if they are undefined in the environment that `conda-build` is invoked from. | ||
| - Variables used in single-line jinja2 `for` and `set` statements are now properly included in the variant matrix for some edge cases. | ||
| - Allow undefined jinja variables when a particular metadata block evaluates as skipped. | ||
|
|
||
| ### 🌅 What Got Deprecated or Got Marked for Future [Deprecation](https://github.com/conda-incubator/ceps/blob/main/cep-9.md)? 🌅 | ||
|
|
||
| - Remove `conda_build.build.check_external`. `patchelf` is an explicit conda-build dependency on Linux, so it will always be installed. | ||
| - Remove `conda_build.metadata._get_env_path`. Use `conda.base.context.locate_prefix_by_name` instead. | ||
| - Remove `conda_build.build._construct_metadata_for_test_from_recipe`. Test built packages instead, not recipes (e.g., `conda build --test package` instead of `conda build --test recipe/`). | ||
|
|
||
|
|
||
| ## Changes in Conda-Libmamba-Solver [24.9.0](https://github.com/conda/conda-libmamba-solver/releases/tag/24.9.0) | ||
|
|
||
| To update conda-libmamba-solver, run: | ||
|
|
||
| ```bash | ||
| conda install -n base conda-libmamba-solver=24.9.0 | ||
| ``` | ||
|
|
||
| ### 🔧 What Got Fixed? 🔧 | ||
|
|
||
| - Use Solver instance configuration to initialize the libmamba context without implicitly relying on the conda context settings. | ||
| - Fix conda-build compatibility regression where arch-specific outputs can't be found in the test phase if a noarch output was built first. | ||
|
|
||
| ### 📄 What's New in Documentation? 📄 | ||
|
|
||
| - Add installation workarounds FAQ with conda-standalone. | ||
| - Update user guide to reflect conda-libmamba-solver being the default solver in conda. | ||
| - Include mamba-org/mamba as a required cloned repository for setting up a dev environment. | ||
|
|
||
|
