That makes sense. The strange thing on the other hand is that it only happens for the readme.txt files - I haven't seen it anywhere else so far.
Any way, here's what showed up earlier today:
Events Manager(http://wordpress.org/plugins/events-manager/):
- Installed version: 5.5.2
- Installed version's "Tested up to:" has been "changed" from 3.8 to 3.6
- A section in the changelog "= 5.5.2.1 (dev) =" has been "removed" from the local file.
WordPress Importer(http://wordpress.org/plugins/wordpress-importer/):
- Installed version: 0.6.1
- Installed version's "Tested up to:" has been "changed" from 3.8(original version) to 3.6
- Installed version's "Stable tag:" has been "changed" from 0.6.1(original version) to 0.6
Again - that's not a big issue and I assume it could indeed be due to the developers committing to a tag, instead of into trunk. I usually ignore those issues, since they're obviously not a problem at all.
Thank you for your time,
Nikola
