0.7.0 / 2011-05-21
==================

• Use GOAM [http://github.com/0xe2-0x9a-0x9b/goam] to build and install GoSpeccy
  
• Use Clingon [http://github.com/remogatto/clingon] as the command-line GUI, instead of a C readline wrapper. The readline support is gone.
  
• Use [http://github.com/remogatto/prettytest], instead of an internal copy of the PrettyTest package
  
• Improved audio resampling method which usually produces less noise
  
• Added command-line options: "-hostcpu-profile", "-show-paint", "-audio", "-audio-freq", "-audio-hq"
  
• New script functions: cmdLineArg() string, fullscreen(bool), showPaint(bool), audioFreq(uint), audioHQ(bool)
  
• Renamed script functions: sound(bool) --> audio(bool)
  
• Performance optimizations: store events events in an array (instead of storing them in a linked-list), do not try to use uninitialized Go variables, lower number of conversions between numeric types with different bit-lengths, do not allocate memory when computing the address of a pixel in a SDL surface, do not allocate memory when executing certain instructions (INC, DEC, POP, RET, and others), use Go arrays instead of ´container/vector/Vector´, read the ROM file only once instead of reading it on each reset, faster typing of [LOAD ""] when loading from tape
  
• Better display refresh stability thanks to reduced memory allocation. That is: less reasons for the Go runtime to stop the program to perform memory garbage-collection.
  
• Make the Z80 CPU conformance test complete much faster
  
• Add initial support for Kempston joystick
  
• Automatically detect when to pause/unpause the tape. This enables loading of multi-part TAP files, and of programs that expect the audio data to contain periods of silence.
  
• Play 8063 pulses on all TAP headers
  
• Limit the maximum speedup of accelerated loading to 20 - aep
  
• Enable loading of the "VeraMono.ttf" font from "$HOME/.gospeccy" or from the installation directory
  
• Do not initialize SDL if GoSpeccy is unable to detect the type of the program on the command-line
  
• Changing the FPS should now result in fever sound buffer underflows
  
• Do not set GOMAXPROCS if there is an environment variable named ´GOMAXPROCS´
  
• Disable writes to ZX Spectrum ROM (to the first 0x4000 bytes of memory). As a side-effect it enables "RANDOMIZE USR 0" to work correctly.
  
• Change the script help text so that it fits the width of the console when the scale is set to 2
  
• Add Go-SDL TTF version check. Print video surface resolution if in verbose mode
  
• Update to a newer version of Go-PerfEvents that allows GoSpeccy to potentially compile&run in a wider range of software environments
  
• Fix a couple of real&potential bugs, deadlocks and race conditions
  
• Minor updates to the README.md file
