+# Release Notes
+
+Files in this directory constitute manual release notes for a given release.
+When relevant, they should be created prior to that release so that they can
+be included in the corresponding tag message, etc.
+
+To add release notes for a release 1.2.3, create a file named `v1.2.3.md`
+consisting of an initial H2-level header and further notes as desired. For
+example:
+
+```
+## Major changes in v1.2.3
+
+- Files are now synchronized twice as fast on Tuesdays
+```
+
+The release notes will also be included in candidate releases (e.g.
+v1.2.3-rc.1).
+
+Additional notes will also be loaded from `v1.2.md` and `v1.md`, if they
+exist.

+## Syncthing 2 is coming
+
+Syncthing version 1.x will soon be replaced by Syncthing version 2.x.
+Version 2 brings a new database format and various cleanups, but remains
+protocol compatible with Syncthing 1.
+
+More detailed information about Syncthing 2 can be found in the release
+notes at https://github.com/syncthing/syncthing/releases.

+## Major changes in 2.0
+
+- 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.
+
+- 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`. Some options
+  have been renamed, others have become subcommands. All serve options are
+  now also accepted as environment variables. See  `syncthing --help` and
+  `syncthing serve --help` for details.
+
+- 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.
+
+- A "default folder" is no longer created on first startup.
