Support is provided for both forms of the Inkbird IBS-TH2 temperature sensor.
The app has been compiled with settings for performance and compatibility with Android 15.

1. A more accurate Spectrum Peak calculation makes the multi-pitch display more accurate.
2. Celeste settings (beat rates at C3 and C6) can now be saved by name and restored later.
3. The Phase Display strobe speed is now a smooth logarithmic function of the tuning error, which gives more resolution when close to the target pitch and more range when further away from the target.
4. List of historical temperaments is now shown in sorted order alphabetically to make it easier to find the one you want.

Performs key holding functions on organs equipped with a MIDI interface through the use of a MIDI/Bluetooth adapter.

* Optional Dark Mode is now supported.
* Two more temperature sensors for temperature compensation are now supported: the Govee GVH5075 and the Oria Wireless Thermometer.  For a complete list see
  www.tunelab-world.com/bluetoothdevices

* Modified handling of interruptions from phone calls to improve the restarting of Organ Tuner after the call.
* Corrected the reading of the Moat S2 temperature sensor.
* Added support for two more Govee temperature sensors.

Fixed a bug in the iPad version with iOS 14 that caused the displayed menu for automatic Bluetooth temperature readings to be compressed at the top of the screen.  A similar problem existed with the pipe cutoff mode menu.  Both menus are now fully visible in the middle of the iPad screen.

Fixed a problem that prevented entering or editing the offsets that define a non-equal temperament on some devices.

* Added support for three new wireless temperature sensors: Moat S2, Govee H5074, and Inkbird IBS-TH1
* Option for temperature updates every 10 minutes or every 1 minute
* Added gestures for fast control of auto note switching, spectrum display scaling, and resetting offsets
* Added button for quick access to multi-pitch display option
* Changed vertical scaling of spectrum display to always show at least 30% of full scale to examine minor peaks in the spectrum
* Expand mutation rank selector to also offer selection of partials.
* Updated all the context-sensitive help files with more hyperlinks.

1. Added support for new BlueMaestro temperature sensors (2017).
2. Enabled two-fingered reset of Offsets.
3. Offsets are zeroed when doing a calibration.
4. Tone generation now uses the speaker instead of the receiver for a louder tone.

1. A particular remote temperature sensor sometimes caused a crash.  This was fixed.
2. For organ builders, a pipe cutoff calculation has been added to help trim pipes to length.

Fixed "cancel temperament" bug under iOS 9
Eliminated extra ".tem" in temperament name when making a new temperament.

iOS 9.1 compatibility issue fixed.

* More sensitive auto note switching
* Support for additional brands of Bluetooth temperature sensors
* Voicing display showing strengths of 12 harmonics
* iPad screen formatting improved to use full width and height

* Optional automatic temperature setting from a Bluetooth sensor
* Multi-pitch display speeds tuning of mixtures, mutations, and extended choruses
* Generated tone with optional harmonics
* Major 6th mutation rank multiplier corrected to x5/3

Fractional mutation rank multipliers have been added.

The numeric display of tuning error has been upgraded with a more exact calculation that is just as accurate for a 100-cent error as it is for a 1-cent error.  Previously it was less accurate for very large tuning errors, which impacted the cutting of new pipes.

A more robust recovery from interruptions due to phone calls has been implemented.

Support for 4" iPhone screen has been added.

For Celeste ranks you can specify a beat rate pattern for either a constant beat rate or a gradually rising beat rate.

For added visibility the Spectrum Display optionally can be drawn with thick traces.

Spectrum Display resolution improved for low bass notes. Extended coverage of numeric tuning error.  Improved interface for making a new temperament.  Added decibel display for current partial.  Volume indicator changed to logarithmic instead of linear.
