3.8.5 Fixes Security Issue with 3.8.4 PL2 - but unreported?

[محروم.كوم]

Hello,

Could I please get a bit of clarification on the 3.8.5 release?
There seems to be a 3.x password weakness security issue that has been addressed in the 3.7 / 4.0 announcement from today, but it only quickly mentions that 3.8.5 doesn't have this issue.

However, the 3.8.5 announcement lists 4 template changes and some bug fixes, but it doesn't seem to list any bug fix about this password security thing.


Does that mean it was unannounced in the 3.8.5 announcement? But actually fixed?
Or does this mean 3.8.5 users have to re-download and run upgrade.php again to fix this?

Are the plugins involved identified? Could we be informed which ones so we can disable those on the forums? __DEFINE_LIKE_SHARE__
