Hey, just wanted to let you know we did receive your feedback and appreciate the comments. We're in the process of making and have already made some changes to our upcoming release process to address some of these concerns. We want to make it clear that we're not abandoning hardware customers, and that their continued support is important.
There were a handful of issues in 5.3 that caused heartburn on release, that were resolved in 5.3.1. We encourage anyone on 5.3 to go to 5.3.1. I'll put up a Thwack post soon rolling up some LEM updates and changes, and I'll be sure we mention it there.
The issue you're facing with tool profiles was introduced at some point along the way (and is not unique to 5.3.1, nor is it universal) but is something we're investigating and will be resolved in an upcoming release. If you find yourself in that situation (agents appearing in both "contained" and "not contained" lists in Tool Profiles), support can help clear it up.
There were functionality changes in 5.3 for all customers, but whether those features were important to you may be another matter We did a significant long-awaited update to agents (codebase and underlying Java Runtime Environment), we added the ability to customize nDepth export formats, support for Kiwi syslog server, a bunch of connector updates, and the extended node functionality (tracking non-agent devices).
Thanks again for your feedback, and for posting here to Thwack! If anyone else is hesitant about upgrading, feel free to let us know and we'll help guide you through the process.
