Release Notes for TortoiseHg

This wiki page contains last minute notes to users about the releases, which may not be included in the documentation or README files included with the distribution kits. It also contains change information, for users who are interested in what bugs have been fixed, and what features have been added in the current version.

Note that like TortoiseSVN, we recommend to turn off the indexing service on the working copies and repositories, and exclude them from virus scans.

Matching Versions

If you are using TortoiseHG from source, we recommend you use the most recent stable releases of TortoiseHG and Mercurial together. TortoiseHg synchronized version numbers with Mercurial at release 3.0, so you should always use the same major revision number of TortoiseHg as Mercurial for any Mercurial version later than 3.0. For older versions of Mercurial, consult the table in OlderReleaseNotes
