Read the Releases Page for changes history, or Changes in MySQL Workbench 5.2.29.

RPM are now available in official repository for fedora ≥ 13, there are also in my repository for fedora ≥ 11. Previous Fedora versions don't have needed dependencies, such as boost ≥ 1.37.0.

As always :

yum --enablerepo=remi install mysql-workbench

Of course, it was build with mysql-5.1.51

For a good packaging, it is necessary to use system libraries rather than bundled ones. Done for curl, libsigc++, boost, yassl (switch to openssl), ctemplate and mysql-connector-c++ (version 1.1.0, bzr snapshot 895, also available in my repo). For scintilla/silvercity, we'll keep the bundled version because this are modified ones and upstream project doesn't provides shared libraries (no build, no ABI stability).
