MySQL Worbench, the modeling, development and administration graphical tool for MySQL databases is now available as 5.2.41 (GA = stable). RPM for fedora and Enterprise Linux 6 are available in remi repository.
RPM are available in my repository for fedora 14 to 17 and Enterprise Linux 6 (RHEL, CentOS, ...)
As always :
yum --enablerepo=remi install mysql-workbench
Of course, it was build with mysql-5.5.27.
This build use (again) the system mysql-connector-c++.
This new version requires the mysql-utilities package which contains some interesting commands and pyodbc for the new migration wizard. However, the version in fedora repository is quite old and may cause some issues (see Bug #847440).
Update in the official repository should be pushed soon.
