+---
+
+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=24.9.0
+```
+
+
+### ✨ 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.

+
+### ✨ 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`. (#13880, #14267)
+- 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 = ""`.
+- Tweak pending deprecation warning for the upcoming changes in channel defaults.

+- Mark `conda.testing.context_aware_monkeypatch` as pending deprecation. Use `conda.testing.fixtures.context_aware_monkeypatch` instead.
+- Mark `conda.testing.tmp_pkgs_dir` as pending deprecation. Use `conda.testing.fixtures.tmp_pkgs_dir` instead.
+- Mark `conda.testing.tmp_envs_dir` as pending deprecation. Use `conda.testing.fixtures.tmp_envs_dir` instead.
+- 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.
+
+
