Yeah, to a different app written in a leaner, less resource dependant style. Sorry to say, but this old house is just dated and clunky (slow and resource intensive). It's an obvious hodge podge of old code loaded with unnecessary logic and conversions.
.300a brings enhancements with it but it really depends on which modules you're using and/or trying to integrate. For us, it was deemed necessary for fixing bugs prior to bringing Shop Floor Control aboard but it brought lots of upgrade headaches with it that affected our existing modules and the enhancements seem extraneous. Just an opinion.
Otherwise, it's ok I guess. It stills does it's basic job regardless of it's myriad of gremlins....
