User-facing changes

  • Conda has been updated to v25.3.1.
  • The EULA of the installer has been updated.
  • In shell (.sh) installers, using environment variables for the installation directory in interactive installations now requires the envsubst command to be pre-installed.
  • The linux-s390x (IBM Z & LinuxONE) installer is no longer supported.

Bug fixes

  • The channels list in the .condarc file now points to defaults instead of explicit URLs. This helps prevent automatic injection of Anaconda’s main channels into the channel list.
  • In package (.pkg) installers, files created by conda init now have the correct owner.
  • In Windows (.exe) installers, non-printable characters are now no longer printed to the installation log.
