[Xenomai-core] [announce] Xenomai v2.5.4

[Gilles Chanteperdrix <gilles.chanteperdrix@xenomai.org>]

Hi,

you will find Xenomai 2.5.4, aka "Sleep Walk", at the usual place:
http://download.gna.org/xenomai/stable/xenomai-2.5.4.tar.bz2

It contains the usual amount of bug fixes and I-pipe patches update, as 
well as a new piece of nice code: the so-called mayday support, which 
should allow Xenomai watchdog to work less brutally (namely, avoid 
killing the tasks occupying too much CPU, and send them a signal), and 
be the base for a new version of user-space signals in the 2.6 branch.

Alex also pushed a lot of improvements for the analogy support.

So, it seems not everybody has been lazy like me for this last version.

The complete shortlog follows:
