Be in touch with eXo JCR performance & QA process here.

We have modernized our Replication service.
The service new features such as Members priority and
Member 'heart-beat' mechanism will help implement more realistic
JCR Cluster.
Replication BLOBs operations were tested again and some issues fixed.
New articles about Replication/Cluster configuration published on eXo wiki.
We have reviewed set of validation aspects according the JSR-170
specification in our JCR core. JCR Path validation more strict now.
Security level and JCR Permissions upgraded using new eXo Core
Security service.

But lets talk about new features of the eXo JCR 1.10.

We start eXo
Organization Service API implementation on JCR storage.
The service actually transparent for other applications having use
Organization Service API, sure as eXoPlatform Portal or ECM.
Only simple component should be configured.
All existing listeners and initializers can be used with the service.

We step on to SaaS path these days :)
eXo JCR storage in Amazon SimpleDB and S3 are beta now.
Yes as the Amazon services.
Today you can setup eXo JCR (Portal, ECM) on SimpleDB (and S3),
put the application on EC2 and you got it.
It's beta now. Beta status mostly thanks to Amazon... the stuff thanks
to Amazon.
But we run it on demo EC2. Ask us if you are interested!

External Values Storage now can be CASasble.
We are supporting Content-Addressable-Storage.
The feature most useful for usecases where same content may be
stored (duplicated) in different locations.
With the Value storage the Value will stored once (one file)
and will be shared between multiple JCR Properties.

So... add Repository state management, new authentication policy,
WebDAV improvements and REST based access to a JCR content.
Would it be tasty for Web2.0, 3.0?

Try it! Adopt it!
