PLD 3.0 is currently in an early stage of development so even quite radical changes are to be expected.

mmazur is the RM, but quoting him:

I'm the RM, but since I'm not actually doing active development and just fixing the infrastructure from time to time, I've shown pluto how everything works, since he's been the most active and, well, most of the times if you want something, you should discuss it with him. 

Development of Th focuses on the following architectures:

• generic x86-64
• x86 (targets: i486, i686, athlon)
• PowerPC

Support for Alpha, SPARC and i386 wasn't completely dropped, but those architectures will not be part of mainstream development. Additional information will be available at a later date.

In PLD 1.0 and PLD 2.0 noarch RPMs were placed alongside architecture specific packages. This changed in Th and now all packages are kept under paths corresponding to their target architectures (please see the next paragraph to see how to construct such a path).

In Th, RPMs can always be found under th/$treename/$architecture/RPMS/ directory. Currently “PLD” and “test” trees will be used (most users will probably want to stay away from the latter) and “upgrades-*” trees might be used after Th's official release. Do note, that the “ready” tree known from PLD 2.0 will not be used in any way that would make it usable to users (assuming it will be used at all).

Th contains, among many other, the following fresh packages:

• gcc 4.1
• xorg 7.0 with Xgl and compiz

RPM packages are compressed using LZMA, which results in both substantially smaller file sizes and faster decompression
