v0.6

• Git who now respects a .mailmap file in the working tree (thanks to Reddit user jmvidal for this suggestion)
• Added an --until option to all subcommands
• The table subcommand, when given the -c option to sort authors by first commit time (descending), now shows the first commit time in a table column
• Fixed a bug that would understate the number of authors when running the table subcommand using the -l or -f flags, only when there are commits in the commit history introducing no diffs

v0.5

• New -c option on table and tree subcommands allows you to rank authors by first modified time.
• Caching feature: parsed commits are now cached on disk so diffs only have to be computed once. This caching is done on a per-repository basis. Subsequent runs of git who on the same repo will be much faster as a result. Caching can be disabled using the GIT_WHO_DISABLE_CACHE env var (set it to 1 ).
• Non-English names are better supported in the table output from the table subcommand.

v0.4

• Integer numbers that appear in the output are now nicely formatted (thousands columns, abbreviations for > 1 million). Thank you to Roman Scharkov for suggesting this
• Tweaked the number of revisions to send to each subprocess of Git log when tallying commits in parallel. This delivered a small performance improvement when running the tool on certain repositories
• Added a progress indicator when tallying commits in parallel on large repositories
• Fixed the CSV output from the table subcommand so that "lines added/removed" and "files" don't appear as columns when the mode is commits mode or files mode

v0.3

• Fixed a panic that happened when all commits were filtered out using a non-existent author
• git who tree now works in subdirectories of a repository and not just at the top-level
• Releases artifacts are now signed. The public key has been committed to the repository here

v0.2
