All platforms
New _MEMSOUND function, that allows you to access raw audio data decoded by the _SNDOPEN function.
Added tiling support to PAINT for legacy SCREEN modes.
Holding CTRL while dragging colors sliders in RGB mixer locks all sliders together (useful for generating gray scale values).

$LET lines would be incorrectly indented in some scenarios.
Allows DATA to contain numbers with trailing data type markers, for retrocompatibility with QB4.5.
The IDE will now let you know early on that labels placed between Subs/Functions are not valid, instead of just crashing at C++ compilation. CONST statements are no longer accepted between Subs/Functions either (they would be accepted in previous versions, but inaccessible).

QB64 Version 1.4 - Changelog
First things first, we have moved development to a new GitHub repository. Follow us at https://github.com/QB64Team/qb64.
Although we don't follow a strict schedule regarding updates to QB64, every once in a while a feature that's been requested gets implemented or a new bug is found and then fixed, and eventually we have enough for a new release.
$NOPREFIX
One big change worth mentioning first, since it affects QB64 code from now on in a big way, is the new $NOPREFIX metacommand.
QB64-specific keywords, those that expand on the original set of keywords from QBasic/QuickBASIC 4.5, which we aim to replicate, are those that start with an underscore. It has been designed that way so that, in the event that you want to load an older program you wrote back in the day that had variables or procedures with identical names, they would not collide with the new keywords, making it possible to use QB64 entirely as you did with QBasic but also add the new functionality without breaking anything.
However, we have over the years been following our userbase create more and more programs that have no dependency whatsoever on older code, which means these aren't just QBasic programs with benefits, but actually QB64-native programs, written from scratch with QB64 in mind.
All that said, the new $NOPREFIX metacommand allows you, for the first time ever, to write QB64 programs without having to add the leading underscore to use the modern keywords.
That will allow code like this:
SCREEN _NEWIMAGE(800, 600, 32)
COLOR _RGB32(255), _RGB32(255, 0, 255)
m$ = "Hello, world!"
_PRINTSTRING ((_WIDTH - _PRINTWIDTH(m$)) \ 2, (_HEIGHT - _FONTHEIGHT) \ 2), m$
DO
_DISPLAY
_LIMIT 30
LOOP UNTIL _KEYHIT
To be written as:
$NOPREFIX
SCREEN NEWIMAGE(800, 600, 32)
COLOR RGB32(255), RGB32(255, 0, 255)
m$ = "Hello, world!"
PRINTSTRING ((WIDTH - PRINTWIDTH(m$)) \ 2, (HEIGHT - FONTHEIGHT) \ 2), m$
DO
DISPLAY
LIMIT 30
LOOP UNTIL KEYHIT
With the new metacommand in use, a program can both use _DISPLAY and DISPLAY, for example. User variables and procedures still cannot start with a single underscore (double underscores are accepted).
Here's the complete changelog for v1.4:
New features
All platforms
New $NOPREFIX metacommand.
New _DEFLATE$() and _INFLATE$() functions, that can be used to compress and decompress text or data strings using zlib, which has been added to our parts system.
New $ASSERTS metacommand and _ASSERT macro.
More bit-related functionality has been added: _READBIT, _SETBIT, _RESETBIT and _TOGGLEBIT.
You can now use _PUTIMAGE to place a portion of an image onto itself (source and destination can now be the same).
New $COLOR metacommand, which adds preset color constants based on HTML color names (per program).
Enhanced support for &B prefixed numbers, so the notation can now also be used in DATA lines and read by INPUT (from file & keyboard).
Windows
Enhancements to $CONSOLE: you can now use statements and functions you are already familiar with for SCREEN 0 but for console output. CSRLIN, POS(0), LOCATE, COLOR, _WIDTH, _HEIGHT, WIDTH (statement), CLS, SLEEP and END have all been reworked to deal with terminal output.
It is now possible to read input while working in $CONSOLE windows using _CONSOLEINPUT (for both keyboard and mouse support) and _CINP (to read individual key strokes).
You can now read the states of _CAPSLOCK, _NUMLOCK and _SCROLLLOCK keys, as well as set their states.
macOS
Basic detection of Retina displays has been implemented and programs should now render properly.
Fixes and improvements
All platforms
The warnings functionality can now be disabled (Options menu).
Numbers expressed in scientific notation now get properly colorized.
Enhanced "Open" and "Save as..." dialogs with added file list (save dialog) and support for wildcard filtering (* and ?).
Fixes a bug that would cause $INCLUDE lines to be duplicated in some scenarios.
Fixes a bug that wouldn't restore VIEW PRINT settings when RUN was called.
Linux
The IDE won't become unresponsive when the mouse pointer leaves the window anymore.
Windows
Fixes a bug that would prevent compilation when $EXEICON was used with $CHECKING:OFF set.
Fixed $VERSIONINFO so the embedded data gets properly displayed in newer versions of Windows.
