The October 2026 release cycle is here, headlined by conda 26.10.0, the special release that makes Rattler the default solver. The classic solver now ships as the separate conda-pycosat-solver plugin, libmamba remains available as an alternative, and the solver plugins and py-rattler received matching updates.
conda and conda-build 26.9.0 are out. Since our June and July update, conda-pypi, constructor, rattler, grayskull, and several other projects have shipped releases too.
The June and July 2026 releases included updates to conda, conda-build, conda-libmamba-solver, conda-pypi, constructor, menuinst, rattler, and more! 🎉 All of these have been released to both defaults and conda-forge channels.
