    Version 1.64.1
    
    - The BigInt type is now _actually_ available, as it wasn't enabled in the
      1.64.0 release even though it was mentioned in the release notes.
    
    - Closed bugs and merge requests:
      * testCommandLine's Unicode tests failing on Alpine Linux [Philip Chimento,
        #296, !399]
      * build: Various clean-ups [Jan Tojnar, !403]
      * Correctly handle vfunc inout parameters [Marco Trevisan, !404]
      * Fix failed redirect of output in CommandLine tests [Liban Parker, !409]
