3.16.2

Enhancements

• Add a --installer-type command line option to build only a single installer type (sh, pkg, exe, or msi), overriding installer_type from the configuration. (#1266)

Bug fixes

• Fix AzureSignTool signature verification failing for installer paths that contain spaces. (#1273)
• Improve the EXE installer path length check added in #1228 to also account for the package cache extraction path (pkgs/<name-version-build>/), preventing installations that were allowed to proceed from failing to extract packages when the install path was long. (#1282)

3.16.0

Enhancements

• EXE: Uninstalling with option "Clear Package Cache" now also performs additional clean-up to account for potentially left over files. (#1213 via #1214)
• Add installer_type: docker support to generate a Dockerfile and staged .sh installer from a constructor build (#1219).
• Add docker_image_format: tar support to build and export a portable Docker image. Requires Docker Buildx (#1219).
• EXE: Add a new error check when the chosen installation path would exceed the Windows 260-character limit, computed from the longest bundled file path. This reduces the risk of users running into confusing installation failures caused by long paths on Windows. (#1170 via #1228)
• Serialize package records and versions for info.json output. (#1250)
• Add experimental support for building Windows MSI installers (via BeeWare's Briefcase). (#1251 via #646, #967)
• Add constructor --render CLI option to render construct.yaml files. (#1263)

Bug fixes

• Skip creating ~/.conda in shell installers when register_envs is false.
  Avoids a spurious failure when $HOME is read-only. (#1215)
• PKG: Fix incorrect owner name in ownership warning messages. (#1223)
• EXE: Create temporary directories inside $INSTDIR to avoid Windows Defender errors with conda-standalone. (#1243 via #1247)

Other

• CI: Add pip to dev environment (required after conda-libmamba-solver 26.4.0 enabled sharded repodata by default). (#1229)
• CI: Pin micromamba<2.6 due to cache regression (mamba-org/mamba#4250). (#1229)
• Add the installer name, version, platform and type attributes to a .installer.info file in the main workspace directory,
  so this information can be persistently stored. (#1250)

3.15.3

Enhancements

• EXE: Add script environment variables to pre-uninstall scripts. (#1206)

Bug fixes

• EXE: Fix regression that placed the pre-uninstall script in the package cache. (#1205)

Contributors

3.15.2

Enhancements

• EXE: Expose uninstallation options as environment variables for pre-uninstallation scripts. (#1197)

Bug fixes

• PKG: Do not fail the installer when ownership of files in $HOME cannot be changed. (#1177 via #1184)
• Fix TypeError when conda 26.x returns dict from fetch_latest(). (#1196)
• SH: Fix -t flag passing arguments to conda activate. (#1202 via #1203)

3.15.1

Bug fixes

• EXE: Fix an issue where the wrong environment variable was read resulting in uninstallers sometimes failing due to PATH corrupting the value of INSTDIR. (#1174)

Other

• The canary CI environment using the onedir variant of conda-standalone now correctly uses the latest version available. (#1173)

3.15.0

Enhancements

• Add support for installing protected (frozen) conda environments. (#1149)
• An environment variable INSTALLER_PATH is now defined for pre-install and post-install scripts, and set to the path of the installer executable while the installer is running. (#1151)
• EXE: An environment variable INSTALLER_PLUGINSDIR is now also defined, it serves the same purpose as the NSIS variable $PLUGINSDIR. (#1151)
• Add architecture checks to macOS SH and PKG installers. (#1153, #1165)

Bug fixes

• EXE: Resolved an issue where a pre_install script was invoked even if the option was unchecked from the installation options page. (#1152)
• Sign all Mach-O binaries in the _internal directory of conda-standalone to pass notarization. (#1045 via #1159)

Other

• Remove Python 3.9 from the testing suite, include Python 3.13. (#1145)

3.14.3

Bug fixes

• Force symbolic linking of _conda in SH and PKG installers. This fixes a regression introduced by #1090 that made installations fail if _conda already exists in the target location. (#1135)
• EXE: Update calls to built-in function LogSet to instead call the intended macro definition ${LogSet}. (#1141)

3.14.2

Enhancements

• Improve logging experience for EXE installers: (#1108)
  • Use cmd.exe to run commands so that outputs are captured.
  • Output command output in CLI installations.
  • Prevent log builds from writing to log before installation directory exists.
  • Remove registry entries while installation directory still exists so that errors are logged.

Bug fixes

• EXE: Fixed an issue for silent installers where command-line argument /KeepPkgCache was ignored and /NoRegistry would reset the default value. (#1132)

3.14.1

Bug fixes

• EXE: Fix a regression with uninitialized variables that prevented installations from being added to the "Add/Remove Programs" list. (#1124)

Contributors

• @marcoesters
• @lranderssons

3.14.0

Enhancements

• Replace custom Python script with conda-standalone calls. This removes Python as an implicit dependency from installers. (#549 via #1089)
• EXE: Improve handling of options initialize_conda, register_python with their corresponding default values. The behavior of these options with respect to initialize_by_default and register_python_default is now consistent with .sh and .pkg installers. Windows CLI installations now don't add conda to PATH or register Python by default, and command-line arguments are only parsed when installing in silent mode (enabled with the flag /S). (#1003, #1004 via #1105)

Bug fixes

• Ensure cached repodata files are shipped in SH installers. (#1119 via #1121).
