Hi,

I think I have almost done the basic design & implementation work for  
_1.9.0_, which is going to be released today.

A few notes before the release:

- The relase version will be 1.9.0, not 1.9.1 as we have  
announced before. This denotes the fact it is not as  
stable as we expected. But the all incompatible changes  
are done already.

- There already are some known bugs. The relase note will  
include the number of failed tests from standard “make test”  
and “make test-all”.

- The release will be planed to be 3:00pm Japanese Standard Time,  
which is 9 hours ahead of UTC. It may be delayed as we have  
suffered in the previous releases. We try our best not to be too  
late.

- THE 1.9 IS INCOMPATIBLE. YOUR APPLICATION MAY NOT WORK AS IT IS.  
The porting know-how (or porting tools maybe) will not provided as  
of the first release.

Thank you for your kind cooperation.

Can we expect no more features or incompatible changes between 1.9.0 and  
whatever becomes 1.9.1? In other words, would it be safe for us on JRuby  
to start implementing our 1.9 features based on what’s released as  
1.9.0?

Also, does this officially mean that the release is considered  
“unstable”?

Yes, basically, except for the possibility that we have to fix  
something we have designed severely wrong, if any.

|Also, does this officially mean that the release is considered “unstable”?

I don’t consider it “production level”. Bugs may remained. But we  
try making it stable.
