• git: Clone submodules whose URL is scp-like (git@example.com:team/lib.git) or starts with ssh://, using git+ssh.
• Read chunked HTTP responses to their end before reusing the connection. This fixes brz push of large git branches, mostly over HTTPS.
• Do not resend a request whose body came from an already consumed iterator or file; a push sent an empty pack.
• gitlab: Accept numeric project ids.
• git: Ignore peeled ^{} lines in info/refs over dumb HTTP. Branching a repository with an annotated tag failed with RefFormatError.
• workspace.check_clean_tree no longer hashes files inside .gitignore'd directories on git working trees.
