- removed the bignum extensions and qjscalc
- new BigInt implementation optimized for small numbers
- added WeakRef, FinalizationRegistry and symbols as weakrefs
- added builtin float64 printing and parsing functions for more correctness
- faster repeated string concatenation
- qjs: promise unhandled rejections are fatal errors by default
+- added column number in debug information
+- removed the "use strip" extension
+- qjs: added -s and --strip-source options
+- qjsc: added -s and --keep-source options
+- added JS_GetAnyOpaque()
+- added more callbacks for exotic objects in JSClassExoticMethods
- misc bug fixes

- close all predefined methods in repl.js and jscalc.js
Optimization ideas:
-- 64-bit atoms in 64-bit mode ?
+- use 64 bit JSValue in 64 bit mode
+- use JSValue as atoms and use a specific constant pool in functions to
+ reference atoms from the bytecode
- reuse stack slots for disjoint scopes, if strip
- add heuristic to avoid some cycles in closures
-- small String (0-2 charcodes) with immediate storage
+- small String (1 codepoint) with immediate storage
- perform static string concatenation at compile time
-- optimize string concatenation with ropes or miniropes?
- add implicit numeric strings for Uint32 numbers?
- optimize `s += a + b`, `s += a.b` and similar simple expressions
- ensure string canonical representation and optimise comparisons and hashes?
-- remove JSObject.first_weak_ref, use bit+context based hashed array for weak references
- property access optimization on the global object, functions,
prototypes and special non extensible objects.
- create object literals with the correct length by backpatching length argument

+QuickJS (version @value{VERSION}) is a small and embeddable Javascript
+engine. It supports most of the ES2023 specification
+@footnote{@url{https://tc39.es/ecma262/2023 }} including modules,
+asynchronous generators, proxies and BigInt.
@section Main Features
--- /dev/null
+The executables included in this archive run on Linux, Mac, Windows,
+FreeBSD, OpenBSD and NetBSD for both the ARM64 and x86_64
+architectures.
+
+Platform Notes:
+
+- if you get errors on Linux, you should disable the binfmt_misc
+ module which automatically invokes wine with Windows executable:
+
+sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/cli' # remove Ubuntu's MZ interpreter
+sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/status' # remove ALL binfmt_misc entries
+
+- Under Windows, you can rename the executables with a .exe extension.
+
+- Use the --assimilate option to build a platform specific binary for
+ better startup time:
+
+ ./qjs --assimilate
+
+- See https://github.com/jart/cosmopolitan for more information about
+ platform specific issues.
