26.7.0

Enhancements

• Cache SolverInputState.installed for the lifetime of a single solve. conda install, conda update, and conda remove against large environments (thousands of packages) are now dramatically faster: a 50,000-record prefix that previously timed out after 5+ minutes completes in ~10 s. (#921)
• Suggest updating conda with conda self if conda self plugin is installed. (#993)

Bug fixes

• Enforce run_constrained/constrains entries that reference virtual packages (e.g. a constrains on __cuda). Virtual packages are now kept present at their detected version/build in solver requests, so the solver -- which runs with allow_uninstall=True -- cannot drop them to dodge such a constraint. __cuda>=13 against a host providing __cuda==12 was silently ignored. (conda/conda#10803 via #962)
