# 1.5 Beta 4 Changes
* MASSIVE reduction in memory usage, and no more explosive RAM growth over time.
* Significant reduction in CPU usage for the UI and analysis threads.
* Documentation improvements.
* Netflow:
* Timestamps were invalid, causing UISP to reject the input.
* Move to a lock-free collection system, eliminating delays and lowering CPU usage.
* Fixed automatic provisioning of Long-Term Stats subscribers.
* User Interface:
* “Top X” tables in the UI are now buffered for smoother output.
* Improvements to graph consistency in UI.
* Network panel on customers now buffers and fades entries out, so it’s possible to read rather than continually jumping.
* TCP Retransmits are now displayed as a percentage of TCP packets, giving a much better *relative* scale of where issues are occurring.
* Up/Down is now labeled on packet counts.
* Improved output scaling on numbers trims “.0”
* IPv6 prefix detection is *much* better and won’t cause UI errors.
* Configuration editor now handles floats vs ints correctly.
* Fixed a login error if no authentication cookie is set.
* Improved Sankey redaction.
* Fixed an occasional error that would make the “sponsor us” toast appear incorrectly.
* Sankey coloration fixes.
* Geo.bin file now won’t self-update very often (it tracks ASN data), and only if it has changed on the server-side.
* LTS2: If you’re invited to help us test it, we’re starting early alpha testing. This version includes the client to make that possible. LTS1 will continue to function/gather data.
