Advertising with no crashes
No, usage of the Advertising plugin did not lead to crashes! But crashes could be experienced on some actions, if the plugin was installed...
There was a minor issue with usage of the Advertising plugin under Redmine 2.5.x. And it was quite insignificant – anyway, I have fixed it.
A much more severe issue was that Redmine sometimes crashed, if the plugin was installed! Thus, it crashed, when a big image was uploaded into an advertisement and when an attempt to... copy a project was made.
So, the main reason for this release to come are fixes of these two issues.
