This changes the default number of connections from one to three (one metadata + two data connections). This should give some advantages of multiple connections, while also not being an overwhelming change for larger installations. (Though those may need to tweak their settings anyway, as always.)

## 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.
|
|
|
|
- Multiple connections are now used by default between v2 devices. The new
|
|
default value is to use three connections: one for index metadata and two
|
|
for data exchange.
