It appears that jagels missed the middle '0' in 4.0.1 in his initial comment, making it seem (to me at least) like eZ were recommending that 4.0 should not be used and to hold off until 4.1. The advice was actually to wait for 4.0.1.
Version 4.1 will come with the new TinyMCE based OE instead of (as well as?) the existing OE. The new TinyMCE OE can can also be used in eZ 4.0.x sites (Will the old OE work in 4.1 ?)
eZ 4.1 will also include the following enhancements:
- http://issues.ez.no/12423: add seconds input to date time and time datatypes
- http://issues.ez.no/12539: share compiled templates between site accesses
- http://issues.ez.no/13009: custom validation methos in edit handlers ( based on ideas in http://projects.ez.no/objectvalidation )
The release candidates 4.0.1rc1 & 3.10rc1 have been announced. The announcement contains important information about the troublesome "url alias" issue.
I'm assuming that we'll see 3.9.5 & 4.1.0 soon as well.
