Links to repositories with fresh software post

As you know, fresh software comes out quite often, and the release of 9.10 needs to wait a relatively long time, and hunting out. I propose in this post to collect links to well-known PPAs and repositories with updated applications.
Well, naturally, I will try to periodically add new things to the post.

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

How I am looking for PPA with software that interests me

google: //inurl: + archive site: launchpad.net
If you're lucky, Google will give out a half-car of links to build logs (or even to the PPAs themselves), which make it easy to get to the desired PPA.

And yes - you, naturally, must understand what you are doing and how to get it back. Updates from anywhere can easily break your OS, FS, leg, or even life.

If you have something to supplement the post with, please ask in the comments. Thanks.
