- Add acked_bytes/acked_packets to struct ETCP_LINK (init, reset, increment per ACK)
- Add DEBUG_CATEGORY_BBR (23) for BBR-specific debug output
- Add BBR input/output DEBUG_DEBUG around bbr_main call in etcp_ack_recv
- Add "bbr" category name to debug_config and etcpmon GUI
- Rename NAT types: OPEN->EIM, RESTRICTED->STRICT across all code
- Add flat addr list {type,ip,port,socket_id} to NODEINFO (NODEINFO_IPV4_ADDR)
- Add NODEINFO_IPV4_SOCKET_META for per-socket metadata
- Add NODE_CONNECTIVITY with per-type probe status and min_rtt
- New module: route_connectivity.c/h (probing engine with socket fallback)
- STRICT verified addresses excluded from NODEINFO broadcast
- Trigger probing on new/updated BGP node, cancel on remove/withdraw
- Update NAT type names in etcpmon GUI
- Add rx_dup_count (local) and tx_dup_count (remote via ACK) to ETCP_CONN
- Extend ACK section format: add 16-bit rx_dup_count after last_delivered_id
- Reconstruct 32-bit tx_dup_count from received 16-bit diff
- Update etcpmon protocol and control_server to expose counters
- Update packet dumper for new ACK format
- utun_update.sh: Shell script for updating single instance
* fast mode: git pull + make clean + make
* full mode: complete rebuild with autotools
* Auto-detects project root from script location
* Handles PID-based process stop/start
* Supports Linux and BSD (nproc/sysctl)
* Returns proper exit codes (0-4)
- mass_update.py: Python script for parallel SSH updates
* Parallel execution via ThreadPoolExecutor
* Configurable via JSON (~/.utun_servers.json)
* Supports custom port/user per server
* Timeout and error handling
* Summary output per server
Tools for remote mass deployment of uTun updates via SSH.
- Add timeout_heap_get_size() to get active timer count
- Add global counters in memory_pool: g_total_free and g_total_allocated
- Simplify busy memory calculation to single formula:
busy = memory_pool_get_total_allocated() - memory_pool_get_total_free_blocks()
- Add new IDC_EDIT_ACTIVE_TIMEOUTS and IDC_EDIT_BUSY_MEMORY to GUI
