Enough new things that I would like to make a release 1.1 soon. Top points: Psyco will now inline calls to short functions, almost cancelling the cost of creating small helpers like 'def f(x): return (x+1) & MASK'. And I have rewritten the string concatenation implementation, as the previous one was unexpectedly inefficient: now using 's=s+t' repeatedly to build a large string is at least as efficient as filling a cStringIO object (and more memory-conservative than using a large list of small strings and calling '"".join()' at the end).

Release 1.0 is out. Note that Psyco is distributed under the MIT License, and no longer under the GPL as it used to be.
The plan for the next release is to include a fast low-level interpreter that can be used on non-Intel processors. It will finally make Psyco portable -- althought of course not as fast as it could possibly be if it could emit real machine code.

Psyco is now compatible with the new Python 2.3b1. This and other bug fixes, plus positive feedback, allow me to officially announce the release of Psyco 1.0 (which should take place in a few hour's time, please come back soon!).

Release 0.4.1 is out. A major new feature I recently added is the reduced memory consumption. On some examples, Psyco uses several times less memory than it used to!

The new site is up and running. I will take the current CVS source and release it as a stable version within the next few days.
