Bug fix update.

• Fixed a bug where tables were always created with hard durability, regardless of the durability option (#3128)
• Fixed a bug that caused HTTPS access with r.http to fail under OS X (#3112)
• Fixed a bug in the Python driver that caused pickling/unpickling of time objects to fail (#3024)
• Changed the Data Explorer autocomplete to not override Ctrl+Tab on Firefox (#2959)
• Fixed a bug that caused a crash when a non-directory file was specified as RethinkDB's startup directory (#3036)
• Added native packages for Debian (#3125, #3107)
• Fixed a compilation error on ARM CPUs (#3116)
• Support building with Protobuf 2.6.0 (#3137)

The highlights of this release are support for geospatial objects and queries,
and significant performance upgrades relating to datum serialization (twice as
fast for many analytical workloads). Read the release blog post
for more details.

Only documents modified after upgrading to 1.15 will receive these performance
gains. You may "upgrade" older documents by performing any write that modifies
their contents. For example, you could add a dummy field to all the documents in
a table and then remove it:

r.table('tablename').update({dummy_field: true})
r.table('tablename').replace(r.row.without('dummy_field'))

There are no API-breaking changes in this release.

Compatibility

Backwards-compatible changes

Data files from RethinkDB versions 1.13.0 onward will be automatically
migrated to version 1.14.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:

http://rethinkdb.com/docs/migration/

Secondary indexes now use a new format; old indexes will continue to work, but
you should rebuild indexes after upgrading to 1.14.x. A warning about outdated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:

http://rethinkdb.com/docs/troubleshooting#my-secondary-index-is-outdated

API-breaking changes

The return_vals optional argument for insert, delete and update has
been changed to return_changes, and works with all write operations
(previously, this only worked with single-document writes). The returned
object is in a new format that is backwards-incompatible with previous
versions. Consult the API documentation for these commands for details:

http://rethinkdb.com/api/javascript/insert
http://rethinkdb.com/api/javascript/delete
http://rethinkdb.com/api/javascript/update

The upsert optional argument to insert has been replaced with conflict
and new allowed values of error, replace or update. This is a
backwards-incompatible change. Consult the API documentation for more
information.
