The places schema was changed in Firefox 14. For Native Fennec release, users will be (should be?) on Firefox 10.x when they upgrade, and they will have a schema version in the range 12-20. Native Fennec checks if the Places version is supported before allowing an upgrade. Because it was increased in XUL beta 14, beta users transitioning to native currently will no longer be able to migrate their data. This increases the version check to support the changes in 14. The actual schema changes are inconsequential for Native Fennec.

Comment on attachment 630952 [details] [diff] [review] Patch 1. Update version check We shouldn't need this for our FN14.0 release, but we do need it on the beta channel prior to FN15's uplift. Given that, let's only land on tip of mozilla-beta (as well as mozilla-aurora).
