Espruino 2v09

Another release that's been a long time coming, but with some big improvements!

Bluetooth users specifically will likely really notice that connecting, uploading code and generally interacting with Espruino devices is a lot snappier than it was before!

Bangle.js / Puck.js / Pixl.js / MDBT42Q

• Update S132 Softdevice from 3.0.0 to 3.1.0
  
• Increase MTU from 23 to 53. Doubles Bluetooth bandwidth!
  
• Allow devices to remember the time between reboots (even if RTC is reset)
  
• Use 'low accuracy' GPIOTE for watches so we can shut down the high speed oscillator
  
• Add callback param to 'NRF.restart', allowing code to be called with softdevice disabled
  
• Puck.js: Fix regression where IR LED was left on after transmission
  
• Reset bluetooth advertising after load()/reset()
  
• BLE: Allow 128-bit service data to be decoded
  
  

Bangle.js:

• Increase advertising interval to ease connections
  
• Make the 'home' button more configurable in code
  
• Add Bangle.softOff to allow the RTC to keep running
  
• Don't enter accelerometer power save mode if compass/barometer is in use
  
• Add isXYZOn() functions for GPS/compass/etc
  
• Apply g.drawImage fast paths even if image goes to the edge of the screen
  
• StorageFile now uses 10x bigger chunks which reduces stress on Storage.list()
  
• Storage.list now allows you to specifically request StorageFile, only ever reports first StorageFile chunk
  
• When load(filename) is used, set global variable FILE to the filename (so FILE now reports app name)
  
  
  

General:

• Fix Espruino not sleeping when very low on free memory
  
• Now use exponents when printing doubles >= 1E21 or < 1E-6
  
• Regexp improvements
  
• Util Timer now uses an based on estimated time from the hardware timer itself
  
• Graphics.fillPoly now errors if >64 points (prev was 63)
  
• Graphics: Support for palettes supplied in image strings
  
• Fix Array.forEach when deleting the item you're currently iterating over
  
• Graphics: Allow colors to be specified as '#rgb' strings
  
• Graphics: Antialiased lines now read the background color so overlap nicely
  
• Graphics: Add antialias/colour blending functions like fillPolyAA
  
• Graphics: Fix overdraw when drawing ellipses/circles
  
• Graphics: Fix 8 bit ArrayBuffer scroll not working correctly in some directions
  
• Storage: Fix corruption issue with StorageFile write after a Storage compact
  
• Fix invalid free / SIGFPE errors found using fuzzing
  
• E.getSizeOf() and trace() now don't recurse into references back to the global scope (makes sizes and traces far more useful)
  
• Fix issue parsing r=>print((e=>{})(r))
  
• Add DHE RSA key exchange for TLS/HTTPS
