you have covered everything :)
o I would like to get eSCIMo done before 2.0 gets released (though this is
not
   included in ApacheDS distribution there will be support for easily
including eSCIMo as a webapp)
o there is some interest in having DHCP support in ApacheDS we might need
to look
   into that post 2.0

<br>
as I&#39;m going to be off for one week, and as we just cuut a new reelase,=

I&#39;d like to share some random thoughts about the server, the API,<br>
Mavibot and some other aspects of our project, where we are now, and<br>
what remains to be done in thenear future...<br>
<br>
First, I think we are slowly but consistently closing the gap to a<br>
2.0-RC1. The last release was mainly about fixing some bugs, and the<br>
next one is probably the first RC. What remains to be done in order to<br>
cut this RC1 ?<br>
<br>
ApacheDS<br>
--------<br>
o Make Mavibot a first class partition (althouh still experimental). It<br>
should be possible for anyone to configure the server so that the<br>
partition uses either JDBM or Mavibot, without having to use any weird<br>
JVM options. This is a work in progress, Kiran already pushed some code<br>
that makes it possible to declare a Mavibot partition.<br>
o Avoid the cloning of entries we are returning<br>
o Check the bug list and fix the low hanging fruits<br>
<br>
Mavibot<br>
-------<br>
o make the handling of multiple values more performant. We shuld define<br>
a threshold after which we use a subBtree, instead of creating a<br>
subBtree everytime<br>
o improve the performance of writes : we are updating the BTree headers<br>
and teh RM headers after each phisical page update, whihc is adding<br>
ahuge penalty<br>

<br>
API<br>

Not too much in this area. We are close to completion, at least for 1.0.<br=

<br>
Studio<br>
------<br>
o Add the support of ADS 2.0-RC1<br>
o Add support of Mavibot partition<br>
<br>
That&#39;s all for the short term tasks, as I can see them. I may have<br>
missed some, so please complete this list.<br>
<br>
Otherwise, in a middle term vision, we have many areas where we can<br>
improve the server and the other projects :<br>
<br>
ApacheDS<br>

o switch to MINA 3<br>
o review the way we handle writes : we should wait for the messageSent<br>
