+* Update syncthing to 2.0.15
+* [Full Changelog](https://github.com/syncthing/syncthing/releases/tag/v2.0.15)
+* Database backend switched from LevelDB to SQLite. There is a migration on
+* first launch which can be lengthy for larger setups. The new database is
+* easier to understand and maintain and, hopefully, less buggy.
+* The logging format has changed to use structured log entries (a message
+* plus several key-value pairs). Additionally, we can now control the log
+* level per package, and a new log level WARNING has been inserted between
+* INFO and ERROR (which was previously known as WARNING...). The INFO level
+* has become more verbose, indicating the sync actions taken by Syncthing. A
+* new command line flag `--log-level` sets the default log level for all
+* packages, and the `STTRACE` environment variable and GUI has been updated
+* to set log levels per package. The `--verbose` and `--logflags` command
+* line options have been removed and will be ignored if given.
