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.

QB64 v1.3 - What's new?

New statements and functions:

Drag/Drop support (Windows-only): new statements _ACCEPTFILEDROP, _TOTALDROPPEDFILES and _DROPPEDFILE$ allow your program to accept and handle files dropped from a folder at run-time.
_ECHO: Previously, you could have a $CONSOLE window enabled but to alternate printing to the main program and to the console you'd have to switch _DEST to _CONSOLE, print the text then switch _DEST back to the main program. With the _ECHO command a $CONSOLE-enabled program can output text to the console window without the hassle.
_ALLOWFULLSCREEN: the statement allows you to set the behavior of the ALT+ENTER combo. You can allow only certain modes or disable the combo altogether.
_SMOOTH: returns true (-1) if the current _FULLSCREEN mode has antialiasing enabled or false (0) if disabled.
_RGB32: of course this is not a new function but it has been improved greatly. You no longer need to alternate between _RGB32 and _RGBA32 as it now accepts an optional fourth parameter for alpha. Also: You can create a grayscale color without having to repeat parameters.
_INSTRREV: like INSTR, _INSTRREV allows you to search for a substring inside another string, but unlike INSTR it returns the last occurrence instead of the first one.
_TRIM$: Single function to remove trailing and leading spaces from a string. Macro for RTRIM$(LTRIM$(text$)).
_SHL and _SHR functions for bit-shifting (left/right), as in PRINT _SHL(2, 4) (returns 32) and PRINT _SHR(-8, 3) (returns -1).

Improvements:

Adds Ctrl+Shift+G shortcut to jump to line with error (try the shortcut when your program has an error and the IDE is indicating it on the status area)
New Ctrl+T to toggle comments on the current line or selection (also available via Edit menu and by right-clicking the code)
Updates NanoJPEG to the version 1.3.5 (try loading different jpg files to see if all works well)
Makes F5 run detached by default. (you no longer get an unresponsive IDE while your program is running; equivalent to Ctrl+F5 in older versions).
Disables maximize box when $RESIZE isn't enabled. (Windows only -> remember when a non-resizable window would still show Maximize and when you clicked it the window would just move to the top-left corner? That won't happen anymore).
Quick Navigation (back arrow) can now be disabled in the Search menu.
It is now possible to have variable-length strings in User Defined Types (UDTs).
[Windows version] Mingw compiler upgraded to version 8.1.0. A 64-bit package is now available officially.
New warnings system indicates when a declared variable isn't used and also when a constant is redefined with the same value - useful for using multiple libraries that define TRUE/FALSE for example (instead of an error stopping compilation, a warning is displayed).

Fixes:

Tab in included files won't generate an error anymore.
A bug that would cause an include line to be duplicated when resizing the IDE.
A bug that would not allow reassigning precompiler $LET variables.
A memory leak involving PRINT USING and TAB().
_PRINTSTRING not using the passed image handle parameters.
Selecting a disabled menu item with a hot key would crash the IDE.

The QB64 team proudly presents QB64 V1.1

---

To install, simply extract to a new directory (and for Linux/Mac, run the setup script). Extracting on top of a previous version is not supported, and you risk ending up with a broken compiler.

This version of QB64 no longer has any components under the GPL. Most components are under suitably permissive licenses to produce closed source programs, with the exception of the sound subsystem. See the LICENSE folder for more detail.

This release contains changes across the board, fixing bugs, adding useful new features, and even improving QB45 compatibility in some minor corner cases. Below is a (almost) complete changelog, as well as a list of all new commands.

Have fun!

---

IDE/Compiler frontend:

-   A new configuration system, with settings stored in internal/config.txt. This also comes with lots of new things for you to twiddle and customise the IDE just the way you like (take a look under the Options menu).
-   Resizing the window is handled more gracefully.
-   Several code-eating bugs (where chunks of code would disappear while being edited) have been fixed.
-   Mouse buttons can be swapped, for those who like to use left-handed mice.
-   SUBs/FUNCTIONs can be indented.
-   Current SUB/FUNCTION name and * (for unsaved changes) is shown in the program name bar.
-   Right-clicking in the source gives a menu with useful options.
-   Double-clicking in the source selects a word.
-   New shortcuts: Ctrl-S Save; Ctrl-G Goto line; Ctrl-F3 Find.
-   Pressing tab with selected code increases indentation (disable the auto-formatter to see it).
-   Typing _RGB( or associated function prompts you to press Shift-Enter to open a colour picker.
-   If enabled, executables will be saved in the same directory as the source file.
-   Add an option to pass command-line arguments when lauching via F5.
-   Add -o (output file), -s (settings), -h/-help command line options (see help output for more info).
-   Ctrl-Backspace erases an entire word, on platforms where such a key combination can be detected.

Compiler:

-   Some convenience substitutions (ENDIF -> END IF), auto-adding ; between PRINT items improve compatibility with old source, especially GW-BASIC programs.
-   Tightened syntax checking in several places to prevent more mysterious errors, such as internal compiler error or C++ compilation failed.
-   Allow variable names such as data.db for compatibility with QB45.
-   Add a precompiler for selective compilation: $LET, $IF, $ELSE, $ELSEIF, $END IF. Great for surrounding DECLARE LIBRARY blocks that are platform dependent.
-   Add _INCLERRORFILE$ and _INCLERRORLINE to return error information when it occurs in an include file.
-   Add _COMMANDCOUNT for number of commandline arguments and allow passing an integer argument to COMMAND$() to get a particular commandline argument.
-   Add SELECT EVERYCASE, which executes every CASE that matches, not just the first.
-   Add OPTION _EXPLICIT to give an error on implicitly declared variable names.
-   _PI now takes an optional multiplier as an argument.
-   Add $EXEICON to build an icon into the program itself (applicable to Windows only).
-   _ICON with no parameters now uses the one built in with $EXEICON.

Runtime:

-   Fix scrollwheel on Linux.
-   OPEN "SCRN:" FOR OUTPUT AS [#1](https://github.com/Galleondragon/qb64/issues/1) now causes output to [#1](https://github.com/Galleondragon/qb64/issues/1) to be printed onscreen.
-   Fix SHELL() to return correct exit codes on Linux.
-   VAL() can now parse binary numbers with &B.
-   VAL() handles very large numbers better.
-   Fix _EXIT on Linux.
-   PLAY correctly defaults to T = 120 on invalid value.
-   Fix loading of some PNG files that previously gave an error.
-   Make EOF read ahead one byte as per QB45.
-   Fix play speed of some audio files.
-   Fix TCP/IP on Linux.
-   Reimplement _MOUSEMOVE

New commands:

-   _SCALEDWIDTH
-   _SCALEDHEIGHT
-   _SCREENHIDE
-   _INCLERRORLINE
-   _INCLERRORFILE$
-   _MOUSEPIPEOPEN
-   _MOUSEINPUTPIPE
-   _MOUSEPIPECLOSE
