-To easily generate the entries for the trac Wiki release pages, use a `git log` approach:
-
-- List of latest changes (example, get from GitHub release page)
-   - https://github.com/OSGeo/grass/compare/releasebranch_7_8@%7B05-05-20%7D...releasebranch_7_8@%7B09-26-20%7D
-- identify start and end commit hash
+To easily generate the entries for the trac Wiki release page, use the `git log` approach:
 - extract entries from oneline git log and prepare for trac Wiki copy-paste:
 
 ```
-#START=76d5988
-#END=8a81328
-##git log --oneline | sed -n "+^$START+,+^$END+p;+^$END+q"

+# get date of previous release from https://github.com/OSGeo/grass/releases
