where can I get more information about the following issues that are fixed in Simplelink SDK 5.30 in the 15.4 stack? (list from https://software-dl.ti.com/simplelink/esd/simplelink_cc13xx_cc26xx_sdk/5.30.01.01/exports/docs/ti154stack/release_notes_ti154stack_4_30_00_00.html)

TI154STACK-3919 Fix issue in which RSSI threshold MAC PIB not used for CSMA-enabled sub-G PHYs
TI154STACK-3918 Decrease MAC receiver max saturation to a reasonable level for good link indication

Are the fixes in the closed-source part of the stack or are there specific code changes I can view?
Thanks and best regards,
