GRAMPS 2.2.2 (the "We interrupt this program to annoy you and make things generally irritating" release) is available.
This is mainly the bugfix release. In particular, a serious bug has been found and fixed since 2.2.1 that prevented the proper upgrade of the Places data from gramps 2.0.x.
Due to the bug, in any database from 2.0.x opened in 2.2.1 the Places lost their main location data: street, city, county, state, country, etc.
If you were affected by this problem, please make a copy of your backup of the *old* grdb data from 2.0.x and open it with 2.2.2 to properly upgrade the Places data.
Note that this only affects the Places data and only for upgrades from 2.0.x. Any new database created with 2.2.1 is not affected.
As usual, we advise that you make frequent backups of your data in the XML format, just in case anything happens.
