This version fixes several bugs and crashes, all users are encouraged to upgrade. The source code can be downloaded from the KDE servers , packages for your distributions should hopefully be available soon. It is also recommended to use the latest version of the MLT framework (0.8.8) to get the recent bugfixes and improvements.
You will find detailled infos about the new features / fixes on our Kdenlive 0.9.4 info page .
Our efforts will now concentrate on merging the refactoring work started by Till Theato (as a result of our fundraising campain) , and cleaning the codebase to make it easier to evolve and integrate the future developments in the MLT video framework.
As usual, a big thank you to all those who helped us make this release better by giving us feedback and investigating the bugs they found.
You can check the Kdenlive online manual  and forums  for documentation and help.
