Adobe AIR 1.5.1 released

Today Adobe AIR 1.5.1 was released. A relatively minor update contains a new API and enough bugfixes.
In order to take advantage of 1.5.1, application recompilation is not required. At the same time, to use the new API presented in this release, you need to update the application descriptor to 1.5.1 (for more details, see the API section, release notes) and recompile it.
