We are pleased to announce the release of WebAnno 3.6.7, a web-based annotation
tool for a wide range of annotations.

This is a bugfix release.

### Notable changes since WebAnno 3.6.6

- Improved compatibility with Firefox
- Added support for Sentence IDs in WebAnno TSV format

For a full detailed list refer to [2].

Also thanks to all bug reporters, all beta testers, all feature suggesters,
and all users!

### Download

The new version can be downloaded from our website [1].

### Important upgrade notes

Since WebAnno 3.5.0, a newer version of the MySQL JDBC driver is used.
This may require changing the `database.url` field in the `settings.properties`
file and adding the setting `serverTimezone=UTC` to it [5].

An in-place upgrade from WebAnno 3.6.6 to WebAnno 3.6.7 is possible.
Back up your data before the upgrade [6].

When upgrading from WebAnno versions earlier than 3.4.0, be sure to read the release
notes of WebAnno 3.4.0 [4] and perform relevant actions before doing the upgrade.
Before any upgrade, please take the usual precautions making backups of your
WebAnno database and home folder. Observe the general upgrade instructions.
Users may have to explicitly "reload" WebAnno in the browser once.

### License and System requirements

WebAnno is provided as open source software under the
Apache License version 2.

Running WebAnno requires Java version 8 or higher.

We also offer standalone JAR which can be used as a desktop application
or as a UNIX service and does not require an additional Tomcat server.

By default, WebAnno uses an embedded database which is sufficient
for testing. However, the use of a MySQL database is recommended.

WebAnno works best with Chrome and Safari.
