The big news in this release is that MySQL has been jettisoned in favor 
of PostgreSQL for persistent storage.  Much of the business logic has 
been moved into the database in the form of constraints and triggers, 
and this migration will continue until the Perl modules are merely a 
convenient interface which can be replaced by any database-literate 
process.  The bulk of Raymond will then consist of PostgreSQL code.

The catalyst for this move was the discovery that it is too difficult to 
build a platform-independent and yet full-featured communications 
protocol module which can work with Microsoft nodes from a Unix host. 
This left me with two solutions:

a) run Raymond exclusively on Windows for management of both Unix and 
Windows. As you may imagine, I consider this idea abhorrent. ;-)

b) move the business logic into the database, so that multiple processes 
can work with the data safely with no concurrency concerns.  That would 
let me manage each type of host from one of its peers, while having all 
instances of raymond write to and draw from the same data source.

Besides being philosophically superior, option b) gives me a whole world 
of flexible interface options, so that's where we're headed. A side 
effect of this move is that all the object names had to change, because 
Postgres relations are not case-sensitive.  I have also chosen to use a 
couple of non-portable features of the Pg driver.  This version is 
therefore utterly incompatible with its predecessors.

Scripting interface:  POD documentation of POM.pm and HostMgr.pm is 
fully up to date ('man Raymond::POM' and 'man Raymond::HostMgr' after 
install). The reference/overview document is sadly not, and has 
therefore been removed from this release.  I will update it as soon as I 
can.

Cheers -d
