Syncthing v2.0.0-beta.8 release notes

Major changes

Database backend switched from LevelDB to SQLite. These 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.
Deleted items are no longer kept forever in the database, instead they are forgotten after six months. If your use case require deletes to take effect after more than a six month delay, set the --db-delete-retention-interval command line option or corresponding environment variable to zero, or a longer time interval of your choosing.
Modernised command line options parsing. Old single-dash long options are no longer supported, e.g. -home must be given as --home. All serve options are now also accepted as environment variables.
Rolling hash detection of shifted data is no longer supported as this effectively never helped. Instead, scanning and syncing is faster and more efficient without it.
