V1.70

• New file format for secondary and IP settings. This version of the firmware converts old to new.
• SID will boot into either Idle or SA mode depending on what was used before reboot/power-down (SD card required); "Boot into SA" option removed. Current mode is saved 10 seconds after activation (or upon fake-power-down or a controlled reboot such as when changing settings in Config Portal)
• Add option to show positive IR feedback (=successful commands) on display. Can be changed through Config Portal or *62 (every change is saved).
• Add option to show IR command entry progress feedback on display. Can be changed through Config Portal or *63 (every change is saved).
• Changed games IR keys: 1 new game, 5 pause, 9 quit
• "Peaks in SA" setting changes through *61 are now saved.
• Display MAC address (STA) on WiFi Configuration Page
• Avoid falling back to stand-alone mode too early when TCD stops sending packets
• Config files are now only written if actually changed which prolongs Flash life-span.
• Code optimizations and fixes.

V1.63

• SA: Shift frequency bands slightly to better match mic frequency response and possibly batch-to-batch dispersion; better pace-keeping; clean up arduinoFFT.
• IO14 is now mirror of the TCD's TT-OUT (in its original function); goes HIGH on start of temporal displacement, LOW on re-entry. There is no lead time. Note: There is no terminal for IO14. It is, however, accessible through a solder pad next to the ESP32, pin no. 8 from bottom.
• BTTFN: Fix keep-alive logic and re-connection after a TCD-reboot.
• BTTFN enhancements in sync with TCD capabilities
• Code refinements

V1.61

• Add support for MQTT v5.0 (tested with mosquitto only). Has no advantages over 3.1.1 (but more overhead)
• Move HA/MQTT settings to separate page
• Add MQTT connection state info on HA/MQTT Settings page
• Show signal in LED field on bad IR input and when starting/quitting keypad-remote-control-mode
• WM: Minor HTML tweaks; make page width dynamic for better display on handheld devices
• Quit games when entering keypad-remote-control-mode; don't allow games to be started while in keypad-remote-control-mode
• Quit Keypad-remote-control-mode if TCD changes "allowed" status
• WM: Require HTTP_POST for params save pages
• Block BTTFN/MQTT commands while "busy"
• Prevent P1-speed from becoming the reason to switch to adapting to TCD-provided speed in speedo-less time-travel sequences
• Sync'd TT: Handle abort in P0

V1.60

• Add command 97 (6097/INJECT_6097) to remotely quit TCD keypad remote control mode
• Allow using TCD command codes 6xxx with MQTT-INJECT command
• Support MQTT-"TIMETRAVEL" command for inter-prop communication with lead time and time tunnel duration attached ("TIMETRAVEL_1234_9876") (TCD 3.9)
• Block WiFi scan during certain animations
• Clean-up stand-alone time travel
• Add BTTFN_NOT_BUSY support (TCD 3.9)
• Allocate MQTT buffer only if MQTT is actually used
• Make TCD notifications synchronous (wakeup, prepareTT)
• Remove BTTFN_MC conditional

V1.59

• Add MQTT command "INJECT_"
• Add WiFi power saving for AP-mode, and user-triggered WiFi connect retry.
• Wakeup on GPS speed changes from <= 0 to >= 0
• Put MQTT commands in command queue instead of executing them directly.
• BTTFN: Fix hostname length issues; code optimizations; minor fix for mc notifications.
• WM: Generate HTML for checkboxes on-the-fly; fix AP shutdown; handle mDNS

V1.58

• WiFi: Set "world safe" country info, limiting choices to 11 channels; Simplify "Forget" using a checkbox; redo signal quality assessment; more event-based waiting instead of delays; number of scanned networks listed is now restricted in order not to run out of memory; do not garble UTF8 SSID; skip SSIDs with non-printable characters.
• Add a delay when connecting to TCD-AP so not all props hammer the TCD-AP at the very same time
• Config Portal: Minor restyling

V1.57

• WiFi Manager overhaul; many changes to Config Portal. WiFi-related settings moved to WiFi Configuration page. We no longer use NVS-stored WiFi configs.
• Add "No SD present" banner in Config Portal if no SD present
• Disable MQTT when connected to "TCD-AP"
• Let DNS server in AP mode only resolve our domain (hostname)
• Various code optimizations to minimize code size and used RAM
• Minor fixes

V1.55

• Fix TCD hostname length field
• Config Portqal: Re-order settings; remove non-checkbox-code.
• WiFi Manager: Reduce HTML page sizes
