Something seems to have changed in the package dependencies. Was this intentional?

Does ALL_O_DIRECT apply to both redo and binary logs? Great feature by the way, lets you use that extra memory that would have been otherwise wasted on unnecessary Linux buffer caching.
Mike,
Binary logs are written by MySQL SQL layer not Innodb engine so this setting does not apply to it.
Peter, the “Downloads – binary distributions” is wrongly linked to the previously version (12.4)
Lance,
Thanks for the report – fixed.
JS,
Indeed, library files were moved from -server to more appropriate -shared package.
To successfully update Percona-Server packages you need to update Percona-Server-shared-51 and Percona-Server-server-51 simultaneously either with YUM or rpm command:
# yum update Percona-Server-server-51 Percona-Server-shared-51
or
# rpm -Uhv Percona-Server-shared-51-5.1.54-rel12.5.188.rhel5.x86_64.rpm Percona-Server-server-51-5.1.54-rel12.5.188.rhel5.x86_64.rpm
It seems necessary to add “Provides: virtual-mysql-client” to package percona-server-client in debain version. Some packages depend on this. Example:
$apt-cache showpkg cacti
…
Dependencies: … virtual-mysql-client.
jetstalker,
That makes sense. I filed a bug, it will be resolved in the nearest release.

Thanks!
Although not generally the best idea you can create a dummy package to get cacti installed:
apt-get install equivs
equivs-control dummy-mysql-virtual-client.ctl
— edit dummy-mysql-virtual-client.ctl and make sure
Package:line looks like:Package: virtual-mysql-client
equivs-build dummy-mysql-virtual-client.ctl
dkpg -i mysql-virtual-client.deb
