* P25 Phase 2 now supports control channel decoding and decoder was enhanced to improve decodes. * Radio reference site editor updated for phase 2 sites to allow user to select FDMA or TDMA control. * Decode events are now minimized and de-duplicated. * Fully parsing all phase 1/2 messages from the latest ICD. * Vendor specific messaging recoveries (Moto & Harris). * Patch group management enhancements with stale patch detection. * Tuner editor now fully resets the min/max frequency values * Default traffic channel count increased to 20 (from 3). * ISSI roaming radio and talkgroup values now displayed and aliasable as fully qualified values (e.g. 1234(123.456.7890) * Moto emergency alarm activation messaging support * Expanded list of P25 encryption algorithms * Message (bits) viewer enhanced for P25 phase 1 and phase 2 * IPV4 addresses and UDP ports no longer classified as user values - won't display in event views. * New framework for describing message binary fields that should reduce overall memory footprint and enhance code readability Co-authored-by: Dennis Sheirer <dsheirer@github.com>
