Please note that Neos versions 3.3 up to 4.2 as well as Flow versions 4.3 up to 5.2 enter their security only lifecycle phase and won’t get regular bugfixes anymore. You are advised to update to Neos 4.3 or Flow 5.3 minimum as soon as possible.
As always there might be a final bugfix release version for all of them if there are any changes still pending.
Also note that bug reports shouldn’t be made for these versions anymore.
The mentioned branches will receive another year of security fixes should a security problem come up, so please report these, as always to firstname.lastname@example.org
