Espruino 2v00 released!

Finally there's a new Espruino release - and it's a big one!

Highlights

• Getter and Setter support
  
• for(var i of array) to iterate over elements
  
• More ES6 API functions including Array.find, String.startsWith/endsWith/includes/repeat
  
• Bluetooth LE boards now communicate over twice as fast, while going into an idle mode when not used and drawing significantly less power when connected.
  
• Software Serial Transmit and Receive on any pin
  
• Better vector font rendering
  
• New Graphics improvements, including createImage for easy, readable 1bpp bitmaps, and .dump to output a copy of the current Graphics object as an image in the Web IDE console.
  
• Lots of fixes, and extra checks added based on code fuzzing performed by a few different groups.
  
• Improved Espruino API reference in many areas
  
• You can now add extra code to be executed at boot as .boot0/1/2/3 in Storage
  
• heatshrink library allows access to Espruino's built-in LZSS compression engine from JS
  
• Doubled the IO buffer size on many boards (so FIFO_FULL errors are far less likely)
  
• E.mapInPlace is now extremely powerful for quickly packing/unpacking bits in arrays
  
  

Full Changes

ES5/ES6 features

Check current state at http://www.espruino.com/Features

• Allow for..in to iterate over prototype chains down from Array and Object
  
• Add for(var i of array) to iterate over elements
  
• Added getter and setter support
  
• Add missing ArrayBufferView.filter
  
• Added Array.find and findIndex (also for ArrayBufferViews)
  
• Added String.startsWith/endsWith/includes (#1302)
  
• Added ES6 String.prototype.repeat
  
  

Performance/Features

• Added support for Software Serial ports (for low baud rates, eg. 9600)
  
• Add extra ReferenceError checks, even if variable is not used
  
• Now check for ReferenceErrors in global scope
  
• Stop parsing blocks if not executing (fix #572)
  
• Switch to non-recursive StringExt copy (fix #1451)
  
• Add E.lookupNoCase to allow searching case-insensitively for Object keys
  
• edit() now chooses the shortest way to describe the function
  
• Added Global isFinite
  
• Enable E.setTimeZone on boards with very little flash memory
  
• Reconstruct start and end newlines when dumping multi-line functions
  
• Add Ethernet.getIP/setIP callbacks for Wiznet to bring them in line with WiFi (fix #1482)
  
• Console now doesn't print quotes around object keys if it's not needed
  
• Added E.toJS to allow very compact JS data stringification (similar to JSON.stringify for JSON2)
  
• Output the current timer number as a comment in dump()
  
• Don't print =undefined to console if line is empty
  
• Use 32 bit floats for E.FFT, not 64 (fix #1443)
  
• Automatically shut down UART if both pin states are changed
  
• Added non-standard Uint24Array, because it's very useful for RGB
  
• Allow btoa to work for arrays as well as Strings (fix #1509)
  
• Improve E.mapInPlace docs, and allow it to work with no map (eg pass straight through)
  
• Allow E.mapInPlace to merge bits from multiple source elements, also add option for msb/lsb first
  
• Double IO buffer size to 256 (1k bytes) on boards with 96k of RAM or more (or NRF52)
  
• Add 'bits' option for Software SPI
  
• STM32 reset pin IRQs before storing the state - makes lost setWatches far less likely
  
  

Graphics

• Pixl.js menu now resets font alignment, and down arrow icon is fixed
  
• Added Graphics.asBMP/asURL/dump - allowing easy debugging of Graphics via IDE
  
• Added Graphics.drawPoly
  
• Fix rounding errors in fillPoly -> improve vector font rendering
  
• Graphics.stringWidth now takes account of newlines
  
• Add Graphics.asImage to turn a Graphics instance into an Image that can be used with drawImage
  
• Add Graphics.createImage to allow creation of a 1 bit image direct from a string
  
  

Flash Memory

• Added Storage.getFree() to return available space
  
• Check Flash Storage for modules when using require
  
• Added 'heatshrink' library to expose built-in heatshrink compression
  
• Search for and execute files '.boot0'/1/2/3 in Storage at boot time if they exist
  
  

Bluetooth Boards

• Add options argument to NRF.connect and BluetoothDevice.gatt.connect, allowing a connection interval to be specified
  
• Start renegotiating speed after 0.1ms, not 5s. Massively improves connect speed.
  
• Add Dynamic Interval Adjustment - default to 2x connection speed, but idle at 10x slower if not used for 2 minutes
  
• Add NRF.setConnectionInterval() to allow connection speed to be set manually
  
• NRF.requestDevice now resolves as soon as a device is found. Faster and better in congested areas
  
• increase JsSysTime accuracy to 2^-20 from 2^-16 - drastically improves Util Timer accuracy
  
• Add Pixl.setLCDPower to allow the LCD to be powered off, more than halving power consumption
  
• Allow NRF.setScan and NRF.findDevices to take the same search filters NRF.requestDevice does (fix #1496)
  
• allow arbirtary baud rates to be specified for UART
  
• Added NRF.HID event for two-way BLE HID communications
  
• Pixl.js: Fix 30s pause when closing sockets on WIZnet W5100 (fix #1306)
  
• MDBT42Q: Add LED2 var in the Espruino interpreter, but don't use it for the bootloader
