2023-08-02 3.4.5:

Enhancements

• Support both .yaml and .txt files in the environment_file key. This enables support for explicit lockfiles (.txt). (#477)

Bug fixes

• Ensure conda metadata is accurate when installers are created from existing environments. (#477)
• On Windows installers, only insert conclusion_file if the extension is .nsi. Ignore otherwise. Also prevents a double final page. (#700 via #701)

2023-02-07 3.4.3:

Bug fixes

• Fix interactive installation in Linux and macOS by ensuring user default is initialized. (#635 via #636)
• Protect all user setable variables in .sh installers against variable substitution. This allows $ signs as part of the license/conclusion/name/version text without causing unexpected $1: unbound variable errors. (#635 via #638)

Docs

• Add documentation for --platform argument, listing out available options. (#620)

Other

• Improve CI reliability by installing NSIS with logging support via conda instead of getting it from sourceforge and manually extracting it. (#631 via #632)

2023-01-25 3.4.2:

Enhancements

• Burn-in constructor version into installers to be able to better support faulty installers. (#604 via #626, #630)

Other

• Switching from print statements to logging. Log levels, filtering, custom formatting strings etc. allow much more verbose and frequent messaging to follow the program flow in case of regular usage and also debugging and development. (#609, #630)
• Add + apply isort via pre-commit (#619)
• Speedup unit tests by factor 5. (#625)
• Add upper conda version bound as with conda >=23.1.0 the local repodata format has changed and write_repodata() has to be updated. See #628 for details. (#627)

Contributors

• @dbast
• @jaimergp

2023-01-18 3.4.1:

Bug fixes

• Fix regression introduced in #558, where post_install scripts were silently ignored on Windows. Affects v3.4.0. (#576 via #614)
• Remove duplicate CI for docs. (#613 via #615)

Contributors

• @dbast
• @jaimergp

2023-01-17 3.4.0:

Enhancements

• Installers support spaces in PREFIX now. Old behaviour (reject chosen path if it contained spaces) is still default. Opt-in by setting check_path_spaces to False. (#449)
• Windows (un)installers can be signed using the new signing_certificate option (#475)
• Users can now add arbitrary files to the installer using the extra_files keyword. (#465 via #500)
• Added two new keys, initialize_conda and register_python, to control whether these options should be offered in the installer or not. (#507)
• Add support for multi-environment installs via extra_envs keyword (#359 via #509, #553, #599)
• Enable alternative solvers by obeying CONDA_SOLVER if set and available. (#531, #597)
• PKG installers now default to the macOS logging system to log messages. UI notifications can be enabled with progress_notifications (off by default). (#535)
• The graphical macOS installer now also displays the version number of the software in the window title. (#536)
• Enable conclusion_text on Windows .exe and Unix .sh installers (#443 via #547 and #550).
• All installers support pre- and post-install scripts and expose the same environment variables: PREFIX, INSTALLER_NAME, INSTALLER_VER, INSTALLER_PLAT, INSTALLER_TYPE. The pre_install_desc key is now available, fulfilling the same role as post_install_desc (#556 via #558)
• Bypass the solver by using an @EXPLICIT input file for conda install commands. (#541 via #559)
• cache files have correct creation and modification timestamps for mamba which looks at the timestamp instead of the _mod value in the cache json (#579).
• Windows GUI installer enhancement to allow for additional custom pages. These new pages can be added after the welcome page and before the conclusion. These extra pages can display text, links, and images. Such pages can be useful in providing additional instructions, guidance, or promotional materials for end-users before they begin using the application they just installed. (#590)
• A new key build_outputs allows to generate extra artifacts besides the installer, like JSON metadata files, solved environments lock files, or licensing reports (#595, #602).
• Improve and publish the documentation to conda.github.io. (#437, #598)
• header.sh and osx scripts hardening by adding set -eu (sh) / set -euo pipefail (bash) and fixing all shellcheck findings. Shell scripts don't stop per default when commands finish with an error causing masked errors and undefined behaviours. set -e changes that behaviour by stoping in all cases where errors happen enabling better error reports on the actual error. If an error should be ignored then a command can be run via $cmd || true. Two test cases running shellcheck ensure that future changes get tested. (#600)

Bug fixes

• Check makensis.exe exit code in verbose mode too (#453 via #475)
• Fix constructor failures when the repo/subchannel only has noarch packages. (#512)
• Fix logging error that would make constructor crash if verbose mode was enabled. (#534)
• Hardcode paths to Apple tools (productbuild, productsign, codesign) to avoid using other tools with the same name in PATH. (#543)
• Prevent pre_uninstall.bat script from being deleted accidentally on cache clearing. (#514)
• Shortcuts will be removed in installations that do not require conda (#461)
• Freshly created download directories are now guaranteed to be writable (#411)
• Windows CI now correctly detects installation problems (#551 and #560)
• Restore the ability to use exclude without solving issues. (#319 via #559)
• Restore the ability to use force reinstall without solving issues. (#456 via #559)
• Fix env.txt indendation to be parsable by mamba again. (#592)
• Fix compatibility with NSIS 3.08 (#526 via #563)
• Make sure cmd calls in the Windows uninstaller use /D for added resilience against Registry issues (#566)
• Fix tests that check for the presence of the tk package in a given environment (#570)
• (For Windows only) Fix for CVE-2022-26526. Installations for "All Users" will not be allowed the option to modify the system PATH environment variable during installation. Installations for "Just Me" will still be allowed the option to add the installation to their PATH environment variable. Additionally, when installing with Administrator privileges, non-admin system Users will no longer have “Write” permissions. (#584)
• Ensure shell installers are POSIX compliant. (#596 via #599)
• Add tests for --conda-exe=<micromamba> and fix found issues on Linux and macOS. Not supported on Windows yet. (#503, #605)

Deprecations

• Officially require Python>=3.7 via setup.py. Older Python versions are EOL and not part of the test matrix since #479. (#606, #610)

Docs

• Improved documentation for post_install scripts (#537)

Other

• Removes the usage of conda._vendor.toolz (#525)
• Removed Maxiconda constructor example and updated Miniconda and Jetsonconda READMEs (and several scripts) to not contain references to Maxiconda anymore. (#470)
• Improve documentation for local channels on Windows (#483 via #564)
• Ensure CONSTRUCT.md is up-to-date with construct.py (#564)
• Remove fragile and unnecessary cleanup steps from CI pipeline (#565)
• Run Windows uninstallers as part of the examples CI (#569)
• Ensure shell installers are POSIX compliant (#599)

  • Fixed bug where constructor crashed if a listed spec was in a noarch-only channel (i.e. without a subdir for the specific platform) (#409).
  • Avoid adding newly installed environment to the list of global conda environments if conda isn't included in the installer itself. (#372)

• SHELL:

  • The user-shell initialisation phase of the installer is no longer included in the install script if there is no conda available in the installed environment.
  • The "test" option is only available if conda is installed in the environment. Previously this would fail in this situation.

2020-09-31 3.1.0:

2019-09-16 3.0.1:

• COMMON:
  • Add dependency on standalone conda executable

2019-08-09 3.0.0:

• COMMON:
  • this utilizes a fundamentally different approach from before. A standalone conda executable (created with pyinstaller) is used to create environments from packages that are shipped with the installers. This allows full support for everything that is supported by the standalone conda. It does add some complexity in terms of menu creation and other operations that rely on knowing whether the env in use (the temporary env for the standalone exe) is the base env. Let's call those prefix-based operations.
