The highlights of this release are:

  • A new administration API
  • Changefeeds on complex queries
  • Numerous improvements and enhancements throughout RethinkDB

Read the release blog post for more details.

Compatibility

Backwards-compatible changes

Data files from RethinkDB versions 1.13.0 onward will be automatically
migrated to version 1.16.x. As with any major release, back up your data files
before performing the upgrade. If you are upgrading from a release earlier
than 1.13.0, follow the migration instructions before upgrading.

Secondary indexes now use a new format; old indexes will continue to work, but
you should rebuild indexes after upgrading to 1.16.x. A warning about outdated
indexes will be issued on startup.

Indexes can be migrated to the new format with the rethinkdb index-rebuild
utility. Consult the troubleshooting document for more information.

The abstraction of datacenters has been replaced by server tags.
Existing datacenter assignments will be converted to server tags automatically.

API-breaking changes

The tableCreate, tableDrop, dbCreate and dbDrop terms have a new set of return values.
The previous return values created and dropped have been renamed to tables_creates / dbs_created and
tables_dropped / dbs_dropped respectively. The terms now additionally return a config_changes field.

Consult the API documentation for these commands for details:
tableCreate, tableDrop, dbCreate, dbDrop

Changefeeds on a table now combine multiple changes to the same document into a single notification if they happen rapidly.
You can turn this behavior off by passing the squash: false optional argument (see the
API documentation for details).

Strings passed to ReQL are now rejected if they are not valid UTF-8.
Non UTF-8 conformant data can be stored as binary data instead.
