2. Version History
(V1.3.0, January 2003) Full regression testing for all U320 products
completed.
(V1.3.0 ALPHA, November 2002) Initial Alpha release.
Added abort and target/lun reset error recovery handler and
interrupt coalessing.
(V1.2.0, November 2002) Added support for Domain Validation and
Hewlett-Packard version of the 39320D and AIC-7902 adapters.
Support for previous adapters has not been fully tested and should
only be used at the customer's own risk.
(V1.1.1, September 2002) Added support for the Linux 2.5.X kernel series
(V1.1.0, August 2002) Added support for four additional SCSI
products: ASC-39320, ASC-29320, ASC-29320LP, AIC-7901.

installation under RedHat might result in two versions of this
