New Mercurial repository format (dotencode).

dotencode is a new repository format for Mercurial that which enhances the fncache repository format.

Previously I wrote about introducing of fncache repository format and problems that occur on old Debian installation.

Story like to be repeated. Debian squeeze use version 1.6.4, while last Cygwin distro come with 1.9.2. So Mercurial repos do not be readable from USB stick on Debian if they created under last Cygwin distro without special magic...
