It includes 12 new features, 257 enhancements, 360 bugfixes.
## Important notes
### Plack and Memcached
On the Koha's about page you can see the status of Plack and Memcached.
The use of Plack and Memcached has been around and stable for more than two years, and must be considered mandatory.
They bring a lot of speed and improve the user experience.
### No more login with the database user
It is no longer possible to use the database user to login into Koha.
You should first create a superlibrarian patron and use it for logging in.
### Debian Stretch users: tmp path changes
If you are using Debian Stretch (9) you should take a look at [bug 20428](http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=20428).
A new entry upload_path must be created in your koha-conf.xml file in order to define a temporary uploaded files directory.
### Dealing with SQL modes
Since latest stables have been released it is not longer needed to modify the configuration of the Database Management System.
See the [dedicated wiki page](https://wiki.koha-community.org/wiki/DBMS_configuration) for more information.
### Change of the database tables charset
[Bug 18336](http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18336) adds the support for Unicode supplementary characters.
We have now a better support of Unicode characters and especially vietnamese and chinese get improved, we also support emojis.
However upgrading the database will require space (a temporary table is created for each of the tables), and time.
It is recommended that the upgrade routine is launched using the command line because it is expected to take more time than usual and could cause timeouts. Packages users will have this run during the upgrade process.
