WEM Changelog

Download release builds from this page.

Versions with no release builds can be downloaded from this link as a development build.

→ 0.11.0

• Removed the RunSuffix option
  • It wasn’t actually used in the code, and functionally RunArgs is probably more fitting
• Try to emit a more sensible error when enabling DXVK/VKD3D-Proton and the configured RunExe doesn’t exist
• When used with --sandbox*, --single-core will prefer firejail’s CPU affinity handling
• Fixed a regression on setting the default WINEARCH
• Fixed DXVK/VKD3D-Proton version having an extra “v” if you added it to your version
• Fixed install-pre/post commands not running when an env was already installed

→ 0.10.3

• Fixed a problem with generating the path to a wine executable for Kron4ek wine builds

Download link

→ 0.10.2

• --dry-run now accurately reflects usage of --install-only-pre and/or --install-only-post
• Improved code for determining if InstallPre and InstallPost should run
• Fixed --no-kron4ek and --no-umu-version not working
• Fixed problems with detecting wine64 capabilities
• Fixed umu or Kron4ek versions/types passed in via command-line not working

Download link

→ 0.10.1

• Added missing env completions for the check command
• Fixed a problem with detecting whether the configured wine is 32 or 64-bit
• Fixed installation happening when it should not have

Download link

→ 0.10.0

• Added --install-only-pre and --install-only-post that allow skipping the main install process and only do the pre or post processes, or both
• Improved detection of 32 or 64-bit wine executables
• Added support for using Kron4ek Wine Builds as a wine runner
  • Set Kron4ekType to a valid Kron4ek Wine release version and WEM will automatically download and extract it, then use it as WineExe for the given env
• Added the info subcommand to print out WEM program configuration and information
• Added the check subcommand for checking that options in a given env are valid
• Added support for using umu-launcher as a wine runner
  • Set UmuVersion to a valid umu release version and WEM will automatically download and extract it, then use it as WineExe for the given env
• Refactored actions/run.go to be vastly simpler code
• RunPre no longer ran when using --exec
• The RunPre and RunPost options have been changed from one command (a single string) to multiple commands (an array of strings)
• Added InstallPre and InstallPost options to run a list of commands before and after installation
• Removed the ge-wine subcommand
  • Those builds are no longer maintained
  • The pattern of using a subcommand to install wine runners has proven to be suboptimal; in the future when other runners are supported they will be implemented similarly to how umu-launcher has been (configure a version to use, it’s then automatically set as the WineExe for the env)
• The firejail CLI generated for --dry-run is no longer created with its own logic (it’s now generated from the actual CLI that gets ran)
• Build against Go 1.24 (from 1.16)
• Fixed a bug where --cpu=0 was always set when using a firejail sandbox
• Sandbox names are sanitized to conform to new firejail requirements
• Only warn about install options if relevant ones are set
• The generic binary (not any of the the distro packages) is now compressed with UPX for a significant size reduction

• Fixed the --no-dlloverrides option

→ 0.9.5

• Added --sandbox-cpu for limiting CPUs in a sandbox via Firejail
• Added the --no-unchanged option for the cfg command to not print settings that haven’t been changed from the default value
• An extra newline is no longer printed with the cfg command
• Improved fish completions
• Moved bash and fish completions to separate files, use the embed directive to include their content

→ 0.9.2

• Fixed several typos
• Removed the SandboxCapsDropAll, SandboxPrivateDev, and SandboxSeccomp options since they are provided by the Firejail wine profile
• Made the error for a missing GeWineDir option give a clue about how to fix it
• Made several required args required at the go-args level rather than doing custom validations all over the place
• wem man will now give an error message when it fails due to missing the mandoc binary
• Doing --no-sandbox now fully disables all other sandbox options
• The install workflow is now more forgiving when you don’t have a value for InstallExpected or RunExe
  • It’s likely you won’t know what exe to expect until after you install and check what you actually have

→ 0.9.0
