A new sound pack is required for this update. See here for instructions on updating sound files.

Notable changes since v2.9:

• Support for audio line out (to connect external speakers for sounds other than the keypad enter & dial sounds) on control boards v1.4 & v1.4.5
• Audio line out settings on/off option 350/351
• Major code cleanup & numerous bug fixes
• Switched keypad sounds to wav for more immediate play-back
• BTTFN: Device type VSR (8xxx) added; AUX is now 5xxx.
• Tweak acceleration sound logic; use with-lead-version of tt sound if time is too short for the accel sound, but long enough for the lead.
• New user-sound: If SD contains "ttaccel.mp3", this file will be played immediately upon initiating a time travel when a speedo is connected, during the acceleration phase, until the start of the actual time travel (at which point it is interrupted by the usual time travel sound). This sound can "bridge" the silence while the speedo counts up.
• 998 restores destination and last time departed displays to user-stored values (ie the ones programmed through the keypad menu, unless overwritten because "Persistent Time Travels" were enabled at some point after programming those times). Command only valid if Persistent Time Travels are off. Pauses time-cycling for 30 mins. Meant as an extension to Exhibition mode for quickly displaying pre-programmed times.
• Time: Time stored in the hardware RTC is now UTC (was local time previously)
• User-set dates/times for Destination and Last Time Departed displays are now considered "secondary settings" and saved to SD (if available and corresponding option is set).
• "Persistent Time Travels" now require the option "Save secondary settings to SD" to be checked, and an SD card to be present.
• Do not "return from time travel" if not on a time travel.
• Config Portal: Propose most used time-zones as datalists for time zone entry.
• Include fork of WiFiManager (2.0.16rc2 with minor patches) in order to cut down bin size
• Audio data (TCDA.bin) can now be uploaded through Config Portal ("UPDATE" page). Requires an SD card present.
• New keypad codes: 300-319 sets volume level; 399 activates volume pot; those are short-cuts to avoid the keypad menu to change the volume selection.
• Speedo GPS: Make speedo update rate user-configurable
• 33+ENTER shows weekday of currently displayed "present time" date.
• Support for MS8607 temp+hum sensor
• Support for various rotary encoders to set Speedo speed
• WiFiManager: Disable pre-scanning of WiFi networks when starting the CP. Scanning is now only done when accessing the "Configure WiFi" page.
• BTTFN: Clients can now discover the TCD's IP address through the TCD's hostname. Uses multicast, not DNS.

• Config Portal: Clicking on header logo jumps to main menu page
• Holding ENTER during boot not only deletes static IP config (as before), but also temporarily clears AP mode WiFi password (until reboot).
• MQTT-induced TT is now always immediate
• If specific config file not found on SD, read from FlashFS - but only if it is mounted
• If SD mount fails at 16Mhz, retry at 25Mhz
• Make timetravel more immediate for some hardware configurations and in some situations
• Exhibition mode: Honor "Make time travels persistent" option properly
• Don't use speedo if not detected
• Auto-expire beep-timer when entering night mode
• Whenever the beep timer is(would be) restarted, the wakeup is sent
• Colons on in night mode

TCD v2.5

This release contains a number of bug fixes and support for new features, again, thanks to Thomas Winischhofer @realA10001986:

Changes Since v2.0

(notable changes bolded)
v2.5

• Add support for BMx820 sensor in speedo (temperature only).
• Modify former "light sensor" keypad menu to not only show measured lux level from a light sensor, but also current ambient temperature as measured by a connected temperature sensor. Rename menu to "Sensors" accordingly.
• Add temperature offset value. User can program an offset that will be added to the measured temperature for compensating sensor inaccuracies or suboptimal sensor placement. In order to calibrate the offset, use the keypad menu "SENSORS" since the temperature shown there is not rounded (unlike what is shown on a speedo display if it has less than three digits).

v2.4

• Added Extended Sound on the Hour: User can now put "hour-xx.mp3" files for each hour on the SD card (hour-00.mp3, hour-01.mp3, ..., hour-23.mp3). If one of the files is missing, "hour.mp3" will be played (if it exists on the SD card)
• Added support for a light sensor to automatically switch TCD to night mode
• Soft-reset the clock by entering 64738 and ENTER
• Minor optimizations for Wifi
• Fixed bug with Destination Time not coming back on after a time travel event

v2.3

• Added auto night-mode presets
• Support for speedo GPS, and getting time/speed
• Re-order Config Portal options
• Add short-cut to set alarm by typing 11hhmm+ENTER (weekday selection must still be done through keypad menu)
• Change default time zone to UTC;
• Change default "time travel persistence" to off to avoid flash wear
• Add weekday selection for alarm
• Enhancements to DST logic
• Add option to disable time travel sounds (in order to have other props play theirs. This is only useful in connection with compatible props, triggered by IO14.)
• Allow time travel to (non-existing) year 0, so users can simulate the movie error (Dec 25, 0000).
• Remove dependency on OneButton and Keypad libraries - integrated and optimized code

v2.2

• Added support for MTK3333 based GPS receivers connected through i2c. These can act as a source of authoritative time (just like NTP), as well as for calculating current speed, to be displayed on a speedo display.
• Implemented completely native time system, handling NTP/GPS, time zones and DST calculation all by itself. This allows using this firmware with correct clocking until the year 9999 (at which point it rolls over to 1), with NTP support until around 2150. Also, DST is now automatically switched in stand-alone mode (ie without NTP or GPS).
• Defer starting the Config Portal so that async WiFi scans don't disrupt our initial NTP request

v2.1:

• Added support for triggering time travel on external props like a flux capacitor, and SID (now IO14)
• Added support for upcoming Time Machine Speedo, complete with time travel, GPS & temp sensor functionality - if connected, the speedo will go up to 88mph, then the time travel sequence will trigger on the TCD. If the speedo reaches 88 via GPS, it will trigger a time travel sequence.
• Added option to re-format SD card
• Added feature to disable WiFi to save power
• Added CPU power save feature
• Added sound when volume is set in the menu
• Reworked keypad and enter key debouncing
• Removed dependency on RTCLib, and added a native slimmed down version
• Changing the brightness in the menu no longer saves immediately afterwards
• Fixed a bug with leap years

Full Changelog: v2.0...v2.5
