Hi there,
Is there any intention to merge this PR in future?
Thanks!

currently versioning is supported with jackalope-jackrabbit by leveraging jackrabbit features for doing the versioning operations.

i have no plan to work on this, but if somebody wants to pick it up i am happy to review a merge request. i don't know how complete & bug free the PR is at this point. it should at least be tested with jackalope/jackalope-doctrine-dbal#316 to know if it works.

ideally, the phpcr-api-tests are also challenged to check if they cover all relevant versioning situations.

Hello, in case one day this MR is picked up, there is a typo in VersionHandler.php line 224 "$frozenNode->hasProperty" should be "$node->hasProperty" and on line 225 "$node->getProperty('jcr:mixinTypes')" should be "$node->getProperty('jcr:mixinTypes')->getValue()"
Minor that, the versionning works fine for me with an XtraDB 8, thanks
