OpenISR users,

We have released version 0.9.1 as an update to the 0.9 series of the OpenISR 
platform.  This update provides many performance improvements over the 0.9 
release as well as usability improvements.  We recommend that all 0.9 users 
upgrade; the upgrade from 0.9 should be easy and should only improve your 
ISR experience.

As usual, links to the source and binary packages are available from here:
http://isr.cmu.edu/download.html

If you are using the apt or yum repositories you should be able to upgrade 
through your package manager.  We have packages for most of the common versions 
of Debian, Ubuntu and Fedora.

IMPORTANT NOTE:  When you upgrade to or install 0.9.1 using a deb or rpm 
package, a group 'isrusers' will be created on your system, and you will 
need to add your username to that group (i.e. "addgroup <username> 
isrusers").

Upgrading from 0.8.x: We still have a few users still using the 0.8 series 
releases.  The upgrade to the 0.9.x series requires a server-side parcel 
conversion, as explained in the 0.9 release notes.  Please contact me 
(mtoups_at_cs.cmu.edu) to begin this process.  We are planning to phase out 
isrserver09 which is hosting the 0.8.x content relatively soon.

As always, contact me or the list if you have questions about installing and 
upgrading OpenISR.
