This is a bugfix release for the current production release family. It replaces MySQL 5.0.20.
Additional SSL Support Information
With version 5.0.20a, SSL support is contained in all binaries
for all Unix (including Linux) and Windows platforms except AIX,
HP-UX, OpenServer 6, and the RPMs specific for RHAS3/RHAS4/SLES9
on Itanium CPUs (
ia64); It is also not
contained in those for Novell Netware. We are trying to add
these platforms in future versions.
Please note that the original 5.0.20 announcement included
inexact wording: SSL support is “included” in both
server and client, but by default not “enabled”.
SSL can be enabled by passing the SSL-related options
--ssl-ca=...) when starting the
server and the client or by specifying these options in an
option file. For more information, see
Using SSL for Secure Connections.
The fix for “Command line options are ignored for mysql client” has been revoked because it introduced an incompatible change in the way the mysql command-line client selects the server to connect to. In the worst case, this might have led to a client issuing commands to a server for which they were not intended, and this must not happen. To help all users in understanding this subject, Invoking MySQL Programs now includes additional explanation of how command options function with regard to host selection. (Bug #16855)
The code of the
yaSSL library has been
improved to avoid a dependency on a C++ runtime library, so a
link with pure C applications is now possible on additional (but
not yet all) platforms. We are working on fixing the remaining
