This is a very major release that adds some long-awaited capabilities to TinyGo, like support for Bluetooth Low Energy via the Nordic Semiconductor nRF51/nRF52. and also support for the Espressif ESP32/ESP8266.

• command-line
  • add cached GOROOT to info subcommand
  • embed git-hash in tinygo-dev executable
  • implement tinygo targets to list usable targets
  • use simpler file copy instead of file renaming to avoid issues on nrf52840 UF2 bootloaders
  • use ToSlash() to specify program path
  • support flashing esp32/esp8266 directly from tinygo
  • when flashing call PortReset only on other than openocd
• compiler
  • compileopts: add support for custom binary formats
  • compiler: improve display of goroutine wrappers
  • interp: don't panic in the Store method
  • interp: replace some panics with error messages
  • interp: show error line in first line of the traceback
  • loader: be more robust when creating the cached GOROOT
  • loader: rewrite/refactor much of the code to use go list directly
  • loader: use ioutil.TempDir to create a temporary directory
  • stacksize: deal with DW_CFA_advance_loc1
• standard library
  • runtime: use waitForEvents when appropriate
• wasm
  • wasm: Remove --no-threads from wasm-ld calls.
