: nRF5x: ensure TIMER1_IRQHandler doesn't always wake idle loop up (fix #1900)
Puck.js: On v2.1 ensure Puck.mag behaves like other variants - just returning the last reading (avoids glitches when used with Puck.magOn)
Fix escaping of `\r` in built-in modules, fixed regression that stopped Espruino WiFi 2v25 from connecting to Wifi
BLE: always return privacy info from NRF.getSecurityStatus(), regardless of connection state
Linux SDL build: mouse events now create `E.on("touch"` events like on CYD
nRF52: Bootloader now doesn't reset RESETREAS
nRF52: If we reboot because of LOCKUP, don't enable DCDC converter
Bangle.js2: Test screen now fails if no DCDC enabled

2v25 : ESP32C3: Get analogRead working correctly
Graphics: Adjust image alignment when rotating images to avoid cropping (fix #2535)
Bangle.js1: Switch to space-optimised sin/atan/atan2 to save enough space to continue building
ESP32C3: don't allow AP *AND* STA mode at the same time - solves issues when just calling 'wifi.connect' at boot
Emulator: ensure we include CallFunction stubs for Promises (fix regression after Promise refactor)
Pin.getInfo() now returns 'output' and 'mode' values, allowing the state of the output register to be queried
E.sendUSBHID now returns false if USB disconnected
(new Array(3)).includes(undefined) fix
USB: Disable software flow control as USB itself handles flow control
Graphics.createArrayBuffer can now be given an ArrayBuffer on initialisation (so it doesn't always try and allocate one)
Added packet transfer protocol for reliable code/file uploads - see README_Protocol.md
STM32F4: shorter timeout used for I2C/etc
STM32: add E.getClock() for retrieving more info on system clocks
Graphics: g.setColor(-1) now sets color to 0xFFFF (previously it would break antialiasing)
Added I2C.unsetup function
STM32: Stay away when USB is connected, even if no app is reading
Remove Ctrl-A/D/E/U/W code handling to free up flash space (the IDE/or VT100 terminals all use escape codes)
Ensure that 1%0.0===NaN (fix #2556)
Ensure Number("1A")==NaN, previously we just parsed the digits we could (fix #2555)
First argument of operators is now dereferenced before parsing second argument (fix #2547)
Ensure x%Infinity===x (fix #2542)
Bangle.js: Remove meridian from default locale.time function (to match 'Languages' app)
nRF5x: When finding the CCCD for a Bluetooth Characteristic, now check at +2 as well as +1 (fix Bluefruit NUS TX)
Jolt.js: Increase Storage area from 40kb to 400kb
nRF5x: Don't add BLE UART write events into the input buffer
ESP32: Timers are now turned off when requested - digitalPulse/soft pwm/writeAtTime more accurate
Bangle.js2: Remove debug log messages from E.showScroller
STM32F4: Update stm32f4xx_ll_usb to fix over-buffered USB CDC tx after being woken from deep sleep
Waveform: Add 'npin' option to allow +/- output on two pins
Waveform: Add ability to play directly from Storage
Puck.js: Remove networking support from default build, add PUCKJS_NETWORK -> espruino_2vxx_puckjs_network.zip builds for those that need it
Bangle.js: Added fastpaths for 2 and 4 bit arraybuffers, and massively improve 1 bit fills
Graphic.createArrayBuffer msb now defaults to true as it's rare to ever need msb:false
Ensure Math.random() can never be `1` as per spec (was unlikely before, but possible)
Add Math.randInt: not in spec, but very useful for embedded
Fix debugging of switch statements (fix #2562)
Network: enable parsing of 'https' URL and TLS flag even even TLS not built in (#2410)
removeListener while executing events no longer stops subsequent listeners from executing (#2151)
jsvObjectIterator is now safe even if not called on something iterable
X.on now always allocates an array - tidies up code (fix #2559)
Bangle.js: E.showMenu no longer sends the internal `l` menu object as argument when running the callback function.
Bangle.js2: GPS request RMC packet automatically (so GPS speed/time work even without AGPS) (fix #2354)
Bangle.js2: GPS now detects binary CASIC packets and splits them into their own GPS-raw event
Bangle.js2: Pass the modified touch event on through both E.showScroller and E.showMenu (to enable more complex interaction with menus).
Bangle.js: Add Bangle.setOptions({manualWatchdog:true}) to enable users to supply their own JS watchdog
Bangle.js2: DFU update from flash now retries if CRC doesn't match
Bangle.js2: Bootloader now shows 'Hold button to turn on' to avoid users assuming it is dead when it's not
Bangle.js2: Bootloader now 'Hold BTN to reboot' not 'BTN1 = REBOOT'/etc
ESP32C3: don't kick connected BLE devices off if reset() is called
ESP32C3: disable warnings about "BT_BTM: BTM_GetSecurityFlags false"
Handle semicolons between field declarations in classes
Ensure that pretokenised Strings are loaded as Flat Strings when executed from a String in RAM
E.nativeCall also checks to see if getting data as a flat string failed (could have caused segfault)
Fix for regression after #2547 fix (left hand operand of maths with a valueOf method)
X.on now allocates a new array for each new handler added, stops new handlers being called for the event that's currently being handled (#2559)
RegExp: add optimisation for RegExp that is simply checking if a string ends with something
Bangle.js: .setUI now only clears back widget if it hasn't been hidden by widget_utils
Fix UtilTimer timings when new task added infront of existing tasks (fix #2575)
Graphics: Fix issue where drawLine for 2px horizontal lines only drew a 1px dot
nRF52: Add E.setComparator to enable interrupts from LPCOMP
Add Serial.isConnected to check if Bluetooth/USB/etc actually connected
Pixl.js: Remove Wiznet W5100 support from default build (there's now a espruino_#v##_pixljs_wiznet.zip without JIT enabled) to ensure we have enough flash to continue builds
Enable nostartfiles optimisation for Pixl,MDBT42 and nRF52DK
STM32F4: Add SDIO support
STM32: Ensure we kick the WDT if auto kicking is enabled and in deep sleep (avoids having to to it manually and wait 30ms for USB to wake up/shut down)
Allow a 'file receive' packet which can request Espruino sends a file as binary packets (also fix files not being closed if transmission fails)
Fix parsing of semicolons in DO with a statement: `do print(a);while(a--);`
In SAVE_ON_FLASH builds (Microbit 1) remove getSerial, Math.LN*/LOG*SQRT* constants, passwords, Serial/I2C/SPI.find, Date.toUTCString
ESP32: add setIP and setAPIP
Graphics.wrapString fix issue with missing final char if immediately after a '.' or other char we can split after (#2572)
Graphics: g.dump/asBMP can now output 16 bit images
Crypto: Add support for AES CCM (enabled on Bangle.js 2)
Add Serial over SWD vis RTT (enabled on Bangle.js 2)
2v24 : Bangle.js2: Add 'Bangle.touchRd()', 'Bangle.touchWr()'
Bangle.js2: After Bangle.showTestScreen, put Bangle.js into a hard off state (not soft off)
Fix for unexpected power draw on newest batch of Bangle.js devices
Puck.js: skip CRT startup code to save ~300b
Fix memory leak when using Pin.getInfo on a pin with ADCs (and non-reporting of analogs)
Puck.js/Jolt.js: Ensure that firmware update ZIPs *do not* perform a self test at boot until they pass (only hex files that are used at the factory do)
