[Tei-council] release notes

Hi all, I have started with the release notes: https://github.com/TEIC/TEI/blob/dev/P5/ReleaseNotes/readme-3.4.0.xml TBC tomorrow. Please have a look at them and add missing bits. I went through the closed issues and added the milestone "Guidelines 3.4.0", but I may have missed some. Please check if something is missing here: https://github.com/TEIC/TEI/issues?q=is%3Aissue+milestone%3A%22Guidelines+3.... I will remove the milestone from the open tickets tomorrow. Best wishes, Martina
