• New file format for secondary and IP settings. This version of the firmware converts old to new.
• "Shuffle" setting changes through buttons are saved (SD required). (Shuffle option removed from CP)
• Superfluous "Brightness" setting removed from CP. Brightness is adjustable using buttons.
• 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.

• P0: Don't jump to TCD speed if it's lower than our currently displayed one, instead wait until TCD caught up.
• Issue a brake warning if brake is on when throttle-up TT should be triggered.
• New sound-pack (RM10)
• BTTFN enhancements in sync with TCD capabilities
• BTTFN: Fall back to DISCOVER upon NOT_DATA timeout. TCD might have got a new IP address.
• BTTFN: Fix re-connection after a TCD-reboot.
• Code refinements

• New sound pack (RM09): Re-do some sounds, add new
• Make TCD<->Remote communication more robust
• Add internal command to react on brake-prohibited TT on behalf of the TCD
• Signal TCD when we want speed even when off
• TCD-controlled TT: If brake is hit while accelerating, TT is aborted
• Fix IP & SOC not being displayed while fake-off
• WM: Minor HTML tweaks; make page width dynamic for better display on handheld devices
• Add support for MQTT v5.0 (tested with mosquitto only). Has no advantages over 3.1.1 (but more overhead)
• Add MQTT connection state info on HA/MQTT Settings page
• If remote controlling is not allowed by the TCD, the Remote, unlike the other props, does not take part in BTTFN-wide time travel. It can, however, still trigger a BTTFN-wide TT.
• WM: Require HTTP_POST for params save pages

Note: Requires TCD firmware 3.10 for proper operation

• Breaking change: Eliminated historical limitation of not having "key8.mp3". User button #8 now plays key8, not key9 as before! Please re-upload your previous key9(l).mp3 as key8.
• Add MQTT commands INJECT_xxx, PLAYKEY_x (x=1-9), STOPKEY, AUTOTHROTTLE_xxx, COASTING_xxx, MOVIEACCEL_xxx, DISPTCDSPD_xxx.
• Add TCD commands 7501-7509 (7511-7519) to play keyX.mp3 (keyXL.mp3) (x=1-9) (Old short-hands 700x for a subset of keyX playback remain as well.)
• Add stand-alone time-travel sequence; triggered through O.O + throttle up or hitting 88 through throttle-up when not connected to a TCD.
• New sound pack (RM08)
• Make separate option for Level Meter on real or fake power
• MP3/File-Renamer: Ignore non-mp3 files; display number of files-to-do while renaming
• Move Music Player init into main_setup()
• Support "stalled P0" (TCD 3.9)
• Block BTTFN/MQTT commands while busy
• Add BTTFN_NOT_BUSY support (TCD 3.9)
• Allocate MQTT buffer only if MQTT is actually used
• Remove hack to skip web handling in on mp3-playback start, remove stopping sound in AP mode on CP access.
• Cancel tcdIsInP0 if networkAbort
• Skip button actions while TTrunning or tcdIsInP0
• Fixes for MQTT inter-prop communication; add support for MQTT TIMETRAVEL command with variable lead (TCD 3.9)
• Remove BTTFN_MC conditional

• Add "Remote fake power controls TCD fake power" feature. Requires TCD firmware >= 3.8.
• Play sound when taking over/releasing TCD fake-power control
• New sound pack (RM07)
• Add CP option to use O.O/RESET (when fake power is off) to either control brightness (as before) or take over/release TCD Fake-Power control
• Allow coasting to be toggled by TCD command (7063)
• Tweak coasting and deceleration curves
• Do not change bri/vol on first press, just display/show
• No calibration when battery is low
• Add WiFi power saving for AP-mode, and user-triggered WiFi connect retry.
• Make reactivation of AP after power-save and reconnection attempts on Fake Power optional.
• Reverse Enable/disable click sound commands for uniformity
• Fix deleting a bad .bin file after upload
• Move HA/MQTT settings to separate page in Config Portal
• Remove volume settings from Settings page
• Fix display of configured power save timer value in CP
• BTTFN: Fix hostname length issues; code optimizations; minor fix for mc notifications.
• WM: Fix AP shutdown; handle mDNS; Generate HTML for checkboxes on-the-fly
• HAVE_VOL_ROTENC compile-time option for RotEnc/Volume support (off in official builds)

• WiFi: Set "world safe" country info, limiting choices to 11 channels; add "show all", add channel info (when all are shown) and proposed AP WiFi channel on WiFi Configuration page; 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.
• Wipe flash FS if alien VER found; in case no VER is present, check available space for audio files, and wipe if not enough.
• Minor code optim (settings, etc.)
• Config Portal: Minor restyling

• 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

• Fix TCD hostname length field
• Extend mp3 upload by allowing multiple (max 16) mp3 files to be uploaded at once
• Config Portal: Re-order settings; remove non-checkbox-code
• Config Portal: Add "install sound pack" banner to main menu
