Links to repositories with fresh software post

As you know, fresh software comes out often enough, and release 9.10 you need to wait for a relatively long time, and poyuzat hunting. I suggest in this post to collect links to well-known PPA and repositories with updated applications.
Well, naturally, I will try to periodically add new clothes to the post.

Deluge PPA - version 1.1.9; twice laid out non-working packages. However, corrected on the same day.
PPA for Brandon Snider - NVidia driver v185.14 + mplayer w / VDPAU support + libxine w / VDPAU. See the instructions for configuring SMPlayer in the PPA description.
X Updates - just backports of fresh stable drivers for all video cards
PPA for telepathy - Fresh Telepathy / Empathy
Mercurial Packagers PPA: Releases - DVCS Mercurial v1.3
Subversion 1.6.x -% name% backports
^{Unless otherwise noted, the distribution is 9.04 Jaunty}

How do I look for a PPA with software that interests me

google: // <packagename> <lastversion> inurl: + archive site: launchpad.net
If you're lucky, Google will give you half a gang of links to build logs (or even the PPA itself), through which you can easily get to the desired PPA.

And yes - you, naturally, should understand what you are doing and how to return it backwards. New clothes from anywhere can easily break your operating system, file system, foot, or even life.
