1.49.4
Version 1.49.4 - New JavaScript features! This version of GJS is based on SpiderMonkey 52, an upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 38. GJS now uses the latest ESR in its engine and the plan is to upgrade again when SpiderMonkey 59 is released in March 2018, pending maintainer availability. Here are the highlights of the new JavaScript features. For more information, look them up on MDN or devdocs.io. * New language features + ES6 classes + Async functions and await operator + Reflect - built-in object with methods for interceptable operations * New syntax + Exponentiation operator: `**` + Variable-length Unicode code point escapes: `"\u{1f369}"` + Destructured default arguments: `function f([x, y]=[1, 2], {z: z}={z: 3})` + Destructured rest parameters: `function f(...[a, b, c])` + `new.target` allows a constructor access to the original constructor that was invoked + Unicode (u) flag for regular expressions, and corresponding RegExp.unicode property + Trailing comma in function parameter lists now allowed * New APIs + New Array, String, and TypedArray method: includes() + TypedArray sort(), toLocaleString(), and toString() methods, to correspond with regular arrays + New Object.getOwnPropertyDescriptors() and Object.values() methods + New Proxy traps: getPrototypeOf() and setPrototypeOf() + [Symbol.toPrimitive] property specifying how to convert an object to a primitive value + [Symbol.species] property allowing to override the default constructor for objects + [Symbol.match], [Symbol.replace], [Symbol.search], and [Symbol.split] properties allowing to customize matching behaviour in RegExp subclasses + [Symbol.hasInstance] property allowing to customize the behaviour of the instanceof operator for objects + [Symbol.toStringTag] property allowing to customize the message printed by Object.toString() without overriding it + [Symbol.isConcatSpreadable] property allowing to control the behaviour of an array subclass in an argument list to Array.concat() + [Symbol.unscopables] property allowing to control which object properties are lifted into the scope of a with statement + New Intl.getCanonicalLocales() method + Date.toString() and RegExp.toString() generic methods + Typed arrays can now be constructed from any iterable object + Array.toLocaleString() gained optional locales and options arguments, to correspond with other toLocaleString() methods * New behaviour + The "arguments" object is now iterable + Date.prototype, WeakMap.prototype, and WeakSet.prototype are now ordinary objects, not instances + Full ES6-compliant implementation of let keyword + RegExp.sticky ('y' flag) behaviour is ES6 standard, it used to be subject to a long-standing bug in Firefox + RegExp constructor with RegExp first argument and flags no longer throws an exception (`new RegExp(/ab+c/, 'i')` works now) + Generators are no longer constructible, as per ES6 (`function* f {}` followed by `new f` will not work) + It is now required to construct ArrayBuffer, TypedArray, Map, Set, and WeakMap with the new operator + Block-level functions (e.g. `{ function foo() {} }`) are now allowed in strict mode; they are scoped to their block + The options.timeZone argument to Date.toLocaleDateString(), Date.toLocaleString(), Date.toLocaleTimeString(), and the constructor of Intl.DateTimeFormat now understands IANA time zone names (such as "America/Vancouver") * Backwards-incompatible changes + Non-standard "let expressions" and "let blocks" (e.g., `let (x = 5) { use(x) }`) are not supported any longer + Non-standard flags argument to String.match(), String.replace(), and String.search() (e.g. `str.replace('foo', 'bar', 'g')`) is now ignored + Non-standard WeakSet.clear() method has been removed + Variables declared with let and const are now 'global lexical bindings', as per the ES6 standard, meaning that they will not be exported in modules. We are maintaining the old behaviour for the time being as a compatibility workaround, but please change "let" or "const" to "var" inside your module file. A warning will remind you of this. For more information, read: https://blog.mozilla.org/addons/2015/10/14/breaking-changes-let-const-firefox-nightly-44/ * Experimental features (may change in future versions) + String.padEnd(), String.padStart() methods (proposed in ES2017) + Intl.DateTimeFormat.formatToParts() method (proposed in ES2017) + Object.entries() method (proposed in ES2017) + Atomics, SharedArrayBuffer, and WebAssembly are disabled by default, but can be enabled if you compile mozjs yourself - Closed bugs: * Prepare for SpiderMonkey 45 and 52 [#781429, Philip Chimento] * Add a static analysis tool as a make target [#783214, Claudio André] * Fix the build with debug logs enabled [#784469, Tomas Popela] * Switch to SpiderMonkey 52 [#784196, Philip Chimento, Chun-wei Fan] * Test suite fails when run with JIT enabled [#616193, Philip Chimento] -

1.49.2
Version 1.49.2 - New feature: When building an app with the Package module, using the Meson build system, you can now run the app with "ninja run" and all the paths will be set up correctly. - New feature: Gio.ListStore is now iterable. - New API: Package.requireSymbol(), a companion for the already existing Package.require(), that not only checks for a GIR library but also for a symbol defined in that library. - New API: Package.checkSymbol(), similar to Package.requireSymbol() but does not exit if the symbol was not found. Use this to support older versions of a GIR library with fallback functionality. - New API: System.dumpHeap(), for debugging only. Prints the state of the JS engine's heap to standard output. Takes an optional filename parameter which will dump to a file instead if given. - Closed bugs: * Make gjs build on Windows/Visual Studio [#775868, Chun-wei Fan] * Bring back fancy error reporter in gjs-console [#781882, Philip Chimento] * Add Meson running from source support to package.js [#781882, Patrick Griffis] * package: Fix initSubmodule() when running from source in Meson [#782065, Patrick Griffis] * package: Set GSETTINGS_SCHEMA_DIR when ran from source [#782069, Patrick Griffis] * Add imports.gi.has() to check for symbol availability [#779593, Florian Müllner] * overrides: Implement Gio.ListStore[Symbol.iterator] [#782310, Patrick Griffis] * tweener: Explicitly check for undefined properties [#781219, Debarshi Ray, Philip Chimento] * Add a way to dump the heap [#780106, Juan Pablo Ugarte] - Fixes in preparation for SpiderMonkey 52 [Philip Chimento] - Misc fixes [Philip Chimento] -
