Dániel Dékány commented on FREEMARKER-183:
------------------------------------------

Unfortunately, it's too a backward incompatible change to be enabled by 
default. Also there's many other things that become better with 
{{incompatible_improvements}}, so people should set it regardless. I know most 
don't... but there's just no way around it.

As a side note, 
{{spring.freemarker.settings.objectWrapper=DefaultObjectWrapper(2.3.33)}} 
should be enough, in case someone doesn't want all the other slightly 
incompatible improvements. Or it can be even more focused. Let's say someone 
used {{incompatible_improvements}} 2.3.29 so far, then  to only enable this 
feature they can use 
{{spring.freemarker.settings.objectWrapper=DefaultObjectWrapper(2.3.29, 
nonRecordZeroArgumentNonVoidMethodPolicy=freemarker.ext.beans.ZeroArgumentNonVoidMethodPolicy.BOTH_PROPERTY_AND_METHOD)")}}.
 I haven't tried these BTW, but I see no reason for them not to work.

Also, I have just force-pushed some internal reworkings into the FREEMARKER-182 
branch. I guess it's close to final... unless I will spot some conceptual 
mistakes. Or somebody else does.
