Plone 4.3.17 soft-released

All the issues we're hitting actually seem to be testbrowser-sided.

Testing and seems we're able to bump to 4.1.1.

4.0.0 and up promise performance improvements for *.find methods.

@Rotonen. Plone 4.3 and 5.1 have lxml 4.2.1 now pinned in coredev. Since you mention in the issue on ftw.testbrowser there are some problems with 4.2.0 , are those relevant for Plone pinnings as well? Meanwhile 4.2.4 is the latest lxml version out.

They are not relevant for Plone, they have everything to do with how we handle HTML in our testbrowser package.
