R devel - Oct 2010 - new.env does not recognize parents from subclasses of "environment"

Dear Developers,

A lot has been changed in the R12.0 with respect to behavior of
"environment"
subclasses.  Many thanks for that.

One small irregularity, though; new.env does not allow the parent to be from S4
subclass.

Error in new.env(parent = new("myenv")) : 'enclos' must be an
environment

I wonder if this is a "planed" behavior.

The use of .xData  slot obviously works:

<environment: 063bb9e8>

Thanks,

Thanks for the report.  Should now be fixed in r-devel and 2.12 
patched (rev 53383).

Please do report any cases where a subclass of environment doesn't 
work.  There are some known cases in locking and active binding, that 
will be fixed in due course.

The workaround for any such problem is usually as.environment().

Thank you Uwe.   The other e-mail cited John mentioning the ./Software/ page.
Indeed those are outdated.

and for about 6 weeks.
The reason has been  ssh host keys changed, disabling a cron job to
run the updates...

I hope this will be ok, within a couple of hours.

Yes, of course, but that has not been the problem here.

Thank you Peter (and Uwe)
