dovecot --version tarball

Hi,

Trying to understand what the version numbers mean. I typically build from the stable tarball and then apply patches as needed.. however since 2.2.25 this hasn't been working (not sure if it worked before or never really looked closely TBH).

http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz - shows GITID 7be1766 however it has commits / changes newer than this.

Also the github tag for 2.2.25 is c1527e5 which doesn't match the source tarball as well.

Should the source tarball and git commit hash be related?

Thanks

Leon
