A Simple Changeset Notifier
This plugin sends changeset diffs in the unified format whenever trac-admin changeset added is invoked.
Be sure that you should turn off Trac's default ticket commit updater notification ([ticket] commit_ticket_update_notify = false in your trac.ini) to prevent duplicated emails for an identical changeset addition event.
If you have any issues, create a new ticket.

See the BitBucket hosted page for the source code. Mercurial is required to clone it.
Most users may be satisfied with post-commit hooks provided by various SCMs, such as Subversion and Mercurial. However, if one addes multiple & heterogeneous projects to one Trac instance, it would be cumbersome to configure every repository and make the email formats consistent. For example, I have a Trac instance with one Subversion repository and three Mercurial repositories. This plugin unifies the changeset notification even for multiple repositories.
