I'm not sure why it hasn't been announced here yet, but PowerMail 5.2.3 build 4406 has been released. Running it now. No problems upgrading, but backed up all just in case. My SpamSieve was already upgraded.
"What's new in PowerMail 5.2.3: (from 5.2.2) + Reliability enhancements for all users: Rolled back the 5.2.2-introduced feature of indexing HTML parts, as an occasional crash in Mac OS X code we were calling caused instability for our users - leading to unfortunate and lengthy rebuilds of sort indices. The reliability of 5.2.3 is therefore greater than that of version 5.2.1. + 10.4.4 compatibility on Intel and PowerPC: As the first deliverables in our long march towards a full Universal version of PowerMail, we are have qualified PowerMail 5.2.3 on Mac OS 10.4.4 on both Intel and PowerPC; the measured performance on an Intel dual-core iMac is actually perceivably faster than on the equivalent G5 iMac. Throughout the migration process, we will continue to ensure smooth and efficient operation on Intel-based Macs. + Performance with first phase of Universal-binary deliverables: Our Intel priorities are focused on the areas promising the most acceleration potential first.
