Add a Sector Release Notes Custom block to 9.5.x

gareth.poole → closed merge request !42

Added to testplan and tested.

Passed with two cosmetic issues:

• the close x is underlined (fix if easy)
• The block should be prefixed with Sector as is ‘Sector Release Notes’ (fix if easy)

magunz → closed merge request !43

@HeikeT MR45 should fix the note #5

Thank you guys! Retested and looking good, ready to merge!
