Update now​

  • Conda: run conda install --name base conda=26.9.4.
  • Mamba: update Mamba, libmamba, and the CA packages together.
  • Pixi: run pixi self-update if you used its installer. Otherwise, update through the package manager you used.
  • Update CA packages separately if you need to keep your current conda version.

Update conda where it is installed, usually base. Update CA packages separately in other environments whose applications use those bundles for HTTPS.

The May 2026 releases span conda, conda-build, conda-libmamba-solver, conda-pypi, and conda-rattler-solver! 🎉 You'll find them on the main and conda-forge channels.

For conda, lockfiles are a first-class workflow now, the CLI is lighter on everyday commands, and there is more under the hood for channel metadata and future dependency specs. Step-by-step opt-in for beta previews—Rattler and conda-pypi—is on New features to try.
