+Mayan EDMS v2.5 release notes
+=============================
+
+Released: July XX, 2017
+
+What's new
+==========
+
+
+Other Changes
+-------------
+- Add view to download a document's OCR text. GitLab issue #215.
+- Add missing OCR migration.
+- Improve error output of the performupgrade command to debug upgrade errors
+  that could stop an upgrade (missing document files, etc).
+- Enable the django-mathfilters app added in version 2.4.
+- Do a complete pull and synchronization of the translations to fix missing
+  translations for Polish. Thanks to Wojtek Warczakowski for the report.
+- Allow null for the SANE source resolution field. Even though the field was
+  marked as allowing blank values it was failing because it is a number field
+  and number fields need to allow explicit null values when left blank.
+- Rename the mayan_task_manager app to task_manager.
+- Make the task manager translatable.
+- Add Turkish to the list of processes languages.
