Version 1.63.90
---------------
- New JS API: The GObject module has gained new overrides:
GObject.signal_handler_find(), GObject.signal_handlers_block_matched(),
GObject.signal_handlers_unblock_matched(), and
GObject.signal_handlers_disconnect_matched(). These overrides replace the
corresponding C API, which was not idiomatic for JavaScript and was not fully
functional because it used bare C pointers for some of its functionality.
See modules/overrides/GObject.js for API documentation.
- New JavaScript features! This version of GJS is based on SpiderMonkey 68, an
upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 60.
Here are the highlights of the new JavaScript features.
For more information, look them up on MDN or devdocs.io.
* New language features
+ The BigInt type, currently a stage 3 proposal in the ES standard, is now
available.
* New syntax
+ `globalThis` is now the ES-standard supported way to get the global
object, no matter what kind of JS environment. The old way, `window`, will
still work, but is no longer preferred.
+ BigInt literals are expressed by a number with "n" appended to it: for
example, `1n`, `9007199254740992n`.
* New APIs
+ String.prototype.trimStart() and String.prototype.trimEnd() now exist and
are preferred instead of trimLeft() and trimRight() which are nonstandard.
+ String.prototype.matchAll() allows easier access to regex capture groups.
+ Array.prototype.flat() flattens nested arrays, well-known from lodash and
similar libraries.
+ Array.prototype.flatMap() acts like a reverse filter(), allowing adding
elements to an array while iterating functional-style.
+ Object.fromEntries() creates an object from iterable key-value pairs.
+ Intl.RelativeTimeFormat is useful for formatting time differences into
human-readable strings such as "1 day ago".
+ BigInt64Array and BigUint64Array are two new typed array types.
* New behaviour
+ There are a lot of minor behaviour changes as SpiderMonkey's JS
implementation conforms ever closer to existing ECMAScript standards and
adopts new ones. For complete information, read the Firefox developer
release notes:
https://developer.mozilla.org/en-US/Firefox/Releases/61#JavaScript
https://developer.mozilla.org/en-US/Firefox/Releases/62#JavaScript
https://developer.mozilla.org/en-US/Firefox/Releases/63#JavaScript

https://developer.mozilla.org/en-US/Firefox/Releases/67#JavaScript
https://developer.mozilla.org/en-US/Firefox/Releases/68#JavaScript
* Backwards-incompatible changes
+ The nonstandard String generics were removed. These had only ever been
implemented by Mozilla and never made it into a standard. (An example of a
String generic is calling a string method on something that might not be a
string like this: `String.endsWith(foo, 5)`. The proper way is
`String.prototype.endsWith.call(foo, 5)` or converting `foo` to a string.)
This should not pose much of a problem for existing code, since in the
previous version these would already print a deprecation warning whenever
they were used.
You can use `moz68tool` from mozjs-deprecation-tools
(https://gitlab.gnome.org/ptomato/moz60tool) to scan your code for this
nonstandard usage.
- Closed bugs and merge requests:
* invalid import on signal.h [#295, !382, Philip Chimento]
* SpiderMonkey 68 [#270, !386, Philip Chimento]
* GObject: Add override for GObject.handler_block_by_func [#290, !371, Philip
Chimento]
Version 1.63.3
--------------
- Closed bugs and merge requests:
* JS ERROR: TypeError: this._rooms.get(...) is undefined [Philip Chimento,
#289, !367]
* Run CI build with --werror [Philip Chimento, #286, !365]
* build: Remove Autotools build system [Philip Chimento, !364]
* gjs-symlink script is incompatible with distro builds [Michael Catanzaro,
Bastien Nocera, #291, !369, !370]

* CI: Create mozjs68 CI images [Philip Chimento, !379]
* Various maintenance [Philip Chimento, !374, !380, !381]
Version 1.58.4
--------------
- Now prints a warning when constructing an unregistered object inheriting from
GObject (i.e. if you forgot to use GObject.registerClass.) In 1.58.2 this
would throw an exception, which broke some existing code, so that change was
reverted in 1.58.3. In this version the check is reinstated, but we log a
warning instead of throwing an exception, so that people know to fix their
code, but without breaking things.
NOTE: In 1.64 (the next stable release) the warning will be changed back into
an exception, because code with this problem can be subtly broken and cause
unexpected errors elsewhere. So make sure to fix your code if you get this
warning.
- Closed bugs and merge requests:
* GSettings crash fixes [Andy Holmes, !373]
- Memory savings for Cairo objects [Philip Chimento, !374]
- Fix for crash in debug functions [Philip Chimento, !374]
Version 1.63.2
--------------
- There is an option for changing the generated GType name for GObject classes
created in GJS to a new scheme that is less likely to have collisions. This
scheme is not yet the default, but you can opt into it by setting
`GObject.gtypeNameBasedOnJSPath = true;` as early as possible in your
prograṁ. Doing this may require some changes in Glade files if you use
composite widget templates.
We recommend you make this change in your codebase as soon as possible, to
avoid any surprises in the future.
- New JS API: GObject.Object has gained a stop_emission_by_name() method which
is a bit more idiomatic than calling GObject.signal_stop_emission_by_name().
- It's now supported to use the "object" attribute in a signal connection in a
composite widget template in a Glade file.
- Closed bugs and merge requests:
* CI: Tweak eslint rule for unneeded parentheses [Florian Müllner, !353]
* Smarter GType name computation [Marco Trevisan, !337]
* Meson CI [Philip Chimento, !354]
* Visual Studio builds using Meson [Chun-wei Fan, !355]

* GObject: Add convenience wrapper for signal_stop_emission_by_name() [Florian
Müllner, !358]
* Various maintenance [Philip Chimento, !356]
* object_instance_props_to_g_parameters should do more check on argv [Philip
Chimento, #63, !359]
* Support flat C arrays of structures [Philip Chimento, !361]
* Gtk Templates: support connectObj argument [Andy Holmes, !363]
- Various build fixes [Philip Chimento]
Version 1.58.2
--------------
- Closed bugs and merge requests:
* GObject based class initialization checks [Marco Trevisan, Philip Chimento,
!336]
* Silently leaked return value of callbacks [Xavier Claessens, Philip
Chimento, #86, !44]
* Crash when calling Gio.Initable.async_init with not vfunc_async_init
implementation [Philip Chimento, #287, !362]
* [cairo] insufficient checking [Philip Chimento, #49, !360]
- Various crash fixes backported from the development branch that didn't close
a bug or merge request.
Version 1.63.1
--------------
- Note that the 1.59, 1.60, 1.61, and 1.62 releases are hereby skipped, because
we are calling the next stable series 1.64 to match gobject-introspection and
GLib.
- GJS now includes a Meson build system. This is now the preferred way to build
it; however, the old Autotools build system is still available for a
transitional period.
- Closed bugs and merge requests:
* GObject: Add convenience wrapper for signal_handler_(un)block() [Florian
Müllner, !326]
* GObject based class initialization checks [Marco Trevisan, Philip Chimento,
!336]
* Meson port [Philip Chimento, !338]

* tests: Fail debugger tests if command failed [Philip Chimento, !350]
* Minor CI image fixes [Philip Chimento, !351]
* Various fixes [Marco Trevisan, Philip Chimento]
Version 1.58.1
--------------
- Closed bugs and merge requests:
* Import wiki documentation [Sonny Piers, !341]
* Smaller CI, phase 1 [Philip Chimento, !339]
* Crashes after setting child property 'icon-name' on GtkStack then displaying
another GtkStack [Florian Müllner, #284, !347]
* GLib.strdelimit crashes [Philip Chimento, #283, !340]
Version 1.58.0
--------------
- No change from 1.57.92.
Version 1.57.92
---------------
- Closed bugs and merge requests:
* tests: Enable regression test cases for GPtrArrays and GArrays of structures
[Stéphane Seng, !334]
* Various maintenance [Philip Chimento, !333, !335]
Version 1.57.91
---------------
- GJS no longer links to libgtk-3. This makes it possible to load the Gtk-4.0
typelib in GJS and write programs that use GTK 4.
- The heapgraph tool has gained some improvements; it is now possible to print a
heap graph of multiple targets. You can also mark an object for better
identification in the heap graph by assigning a magic property: for example,
myObject.__heapgraph_name = 'Button' will make that object identify itself as
"Button" in heap graphs.
- Closed bugs and merge requests:
* Remove usage of Lang in non legacy code [Sonny Piers, !322]
* GTK4 [Florian Müllner, #99, !328, !330]
* JS syntax fixes [Marco Trevisan, Philip Chimento, !306, !323]
* gi: Avoid infinite recursion when converting GValues [Florian Müllner, !329]
* Implement all GObject-introspection test suites [Philip Chimento, !327,
!332]
* Heapgraph improvements [Philip Chimento, !325]
Version 1.57.90
---------------
- New JS API: GLib.Variant has gained a recursiveUnpack() method which
transforms the variant entirely into a JS object, discarding all type
information. This can be useful for dealing with a{sv} dictionaries, where
deepUnpack() will keep the values as GLib.Variant instances in order to
preserve the type information.
- New JS API: GLib.Variant has gained a deepUnpack() method which is exactly the
same as the already existing deep_unpack(), but fits with the other camelCase
APIs that GJS adds.
- Closed bugs and merge requests:
* Marshalling of GPtrArray broken [#9, !311, Stéphane Seng]
* Fix locale chooser [!313, Philip Chimento]
* dbus-wrapper: Remove interface skeleton flush idle on dispose [!312, Marco
Trevisan]
* gobject: Use auto-compartment when getting property as well [!316, Florian
Müllner]
* modules/signals: Use array destructuring in _emit [!317, Jonas Dreßler]
* GJS can't call glibtop_init function from libgtop [#259, !319,
Philip Chimento]
* GLib's VariantDict is missing lookup [#263, !320, Sonny Piers]
* toString on an object implementing an interface fails [#252, !299, Marco
Trevisan]
* Regression in GstPbutils.Discoverer::discovered callback [#262, !318, Philip
Chimento]
* GLib.Variant.deep_unpack not working properly with a{sv} variants [#225,
!321, Fabián Orccón, Philip Chimento]
* Various maintenance [!315, Philip Chimento]
- Various CI fixes [Philip Chimento]
Version 1.57.4
--------------
- Closed bugs and merge requests:
* gjs 1.57 requires a recent sysprof version for sysprof-capture-3 [#258,
!309, Olivier Fourdan]
- Misc documentation changes [Philip Chimento]
Version 1.57.3
--------------
- The GJS profiler is now integrated directly into Sysprof 3, via the
GJS_TRACE_FD environment variable. Call stack information and garbage
collector timing will show up in Sysprof. See also GNOME/Initiatives#10
- New JS API: System.addressOfGObject(obj) will return a string with the hex
address of the underlying GObject of `obj` if it is a GObject wrapper, or
throw an exception if it is not. This is intended for debugging.
- New JS API: It's now possible to pass a value from Gio.DBusProxyFlags to the
constructor of a class created by Gio.DBusProxy.makeProxyWrapper().
- Backwards-incompatible change: Trying to read a write-only property on a DBus
proxy object, or write a read-only property, will now throw an exception.
Previously it would fail silently. It seems unlikely any code is relying on
the old behaviour, and if so then it was probably masking a bug.
- Closed bugs and merge requests:
* Build failure on Continuous [#253, !300, Philip Chimento]
* build: Bump glib requirement [!302, Florian Müllner]
* profiler: avoid clearing 512 bytes of stack [!304, Christian Hergert]
* system: add addressOfGObject method [!296, Marco Trevisan]
* Add support for GJS_TRACE_FD [!295, Christian Hergert]
* Gio: Make possible to pass DBusProxyFlags to proxy wrapper [!297, Marco
Trevisan]
* Various maintenance [!301, Philip Chimento]
* Marshalling of GPtrArray broken [#9, !307, Stéphane Seng]
* Build fix [!308, Philip Chimento]
* Gio: sync dbus wrapper properties flags [!298, Marco Trevisan]
* GjsMaybeOwned: Reduce allocation when used as Object member [!303, Marco
Trevisan]
Version 1.57.2
--------------
- There are now overrides for Gio.SettingsSchema and Gio.Settings which avoid
aborting the whole process when trying to access a nonexistent key or child
schema. The original API from GLib was intended for apps, since apps should
have complete control over which settings keys they are allowed to access.
However, it is not a good fit for shell extensions, which may need to access
different settings keys depending on the version of GNOME shell they're
running on.
This feature is based on code from Cinnamon which the copyright holders have
kindly agreed to relicense to GJS's license.
- New JS API: It is now possible to pass GObject.TypeFlags to
GObject.registerClass(). For example, passing
`GTypeFlags: GObject.TypeFlags.ABSTRACT` in the class info object, will create
a class that cannot be instantiated. This functionality was present in
Lang.Class but has been missing from GObject.registerClass().
- Closed bugs and merge requests:
* Document logging features [#230, !288, Andy Holmes]
* Support optional GTypeFlags value in GObject subclasses [!290, Florian
Müllner]
* Ensure const-correctness in C++ objects [#105, !291, Onur Şahin]
* Programmer errors with GSettings cause segfaults [#205, !284, Philip
Chimento]
* Various maintenance [!292, Philip Chimento]
* debugger: Fix summary help [!293, Florian Müllner]
* context: Use Heap pointers for GC objects stored in vectors [!294, Philip
Chimento]
Version 1.56.2

* Cairo conversion bugs [!286, Philip Chimento]
Version 1.56.1
--------------
- Closed bugs and merge requests:
* Calling dumpHeap() on non-existent directory causes crash [#134, !277,
Philip Chimento]
* Using Gio.MemoryInputStream.new_from_data ("string") causes segfault [#221,
!278, Philip Chimento]
* Fix gjs_context_eval() for non-zero-terminated strings [!281, Philip
Chimento]
Version 1.56.0

Version 1.55.92
---------------
- Closed bugs and merge requests:

* win32/NMake: Fix introspection builds [!274, Chun-wei Fan]
* NMake/libgjs-private: Export all the public symbols there [!275, Chun-wei
Fan]
Version 1.55.91
---------------
- The problem of freezing while running the tests using GCC's sanitizers was
determined to be a bug in GCC, which was fixed in GCC 9.0.1.
- Closed bugs and merge requests:
* gnome-sound-recorder crashes deep inside libgjs [#223, !266, Philip
Chimento]
* Various maintenance [!267, Philip Chimento]
* wrapperutils: Define $gtype property as non-enumerable [!268, Philip
Chimento]
Version 1.55.90
---------------
- New JS API: It's now possible to call and implement DBus methods whose
parameters or return types include file descriptor lists (type signature 'h'.)
This involves passing or receiving a Gio.UnixFDList instance along with the
parameters or return values.
To call a method with a file descriptor list, pass the Gio.UnixFDList along
with the rest of the parameters, in any order, the same way you would pass a
Gio.Cancellable or async callback.
For return values, things are a little more complicated, in order to avoid
breaking existing code. Previously, synchronously called DBus proxy methods
would return an unpacked GVariant. Now, but only if called with a
Gio.UnixFDList, they will return [unpacked GVariant, Gio.UnixFDList]. This
does not break existing code because it was not possible to call a method with
a Gio.UnixFDList before, and the return value is unchanged if not calling with
a Gio.UnixFDList. This does mean, unfortunately, that if you have a method
with an 'h' in its return signature but not in its argument signatures, you
will have to call it with an empty FDList in order to receive an FDList with
the return value, when calling synchronously.
On the DBus service side, when receiving a method call, we now pass the
Gio.UnixFDList received from DBus to the called method. Previously, sync
methods were passed the parameters, and async methods were passed the
parameters plus the Gio.DBusInvocation object. Appending the Gio.UnixFDList to
those parameters also should not break existing code.
See the new tests in installed-tests/js/testGDBus.js for examples of calling
methods with FD lists.
- We have observed on the CI server that GJS 1.55.90 will hang forever while
running the test suite compiled with GCC 9.0.0 and configured with the
--enable-asan and --enable-ubsan arguments. This should be addressed in one of
the following 1.55.x releases.
- Closed bugs and merge requests:
* GDBus proxy overrides should support Gio.DBusProxy.call_with_unix_fd_list()
[#204, !263, Philip Chimento]
* Add regression tests for GObject vfuncs [!259, Jason Hicks]
* GjsPrivate: Sources should be C files [!262, Philip Chimento]
* build: Vendor last-good version of AX_CODE_COVERAGE [!264, Philip Chimento]

* Manually constructed ByteArray toString segfaults [#219, !254, Philip
Chimento]
* signals: Add _signalHandlerIsConnected method [!255, Jason Hicks]
* Various maintenance [!257, Philip Chimento]
Version 1.52.5
--------------
- This was a release consisting only of backports from the GNOME 3.30 branch to
the GNOME 3.28 branch.
- This release includes the "Big Hammer" patch from GNOME 3.30 to reduce memory
usage. For more information, read the blog post at
https://feaneron.com/2018/04/20/the-infamous-gnome-shell-memory-leak/
It was not originally intended to be backported to GNOME 3.28, but in practice
several Linux distributions already backported it, and it has been working
well to reduce memory usage, and the bugs have been ironed out of it.
It does decrease performance somewhat, so if you don't want that then don't
install this update.

* byteArray: Add compatibility toString property [Philip Chimento, !227]
Version 1.53.92
---------------
- Technology preview of a GNOME 3.32 feature: native Promises for GIO-style
asynchronous operations. This is the result of Avi Zajac's summer internship.
To use it, you can opt in once for each specific asynchronous method, by
including code such as the following:
Gio._promisify(Gio.InputStream.prototype, 'read_bytes_async',
'read_bytes_finish');
After executing this, you will be able to use native Promises with the
Gio.InputStream.prototype.read_async() method, simply by not passing a
callback to it:
try {
let bytes = await stream.read_bytes_async(count, priority, cancel);
} catch (e) {
logError(e, 'Failed to read bytes');
}
Note that any "success" boolean return values are deleted from the array of
return values from the async method. That is,
let [contents, etag] = file.load_contents_async(cancel);
whereas the callback version still returns a useless [ok, contents, etag]
that can never be false, since on false an exception would be thrown. In the
callback version, we must keep this for compatibility reasons.
Note that due to a bug in GJS (https://gitlab.gnome.org/GNOME/gjs/issues/189),
promisifying methods on Gio.File.prototype and other interface prototypes will
not work. We provide the API Gio._LocalFilePrototype on which you can
promisify methods that will work on Gio.File instances on the local disk only:
Gio._promisify(Gio._LocalFilePrototype, 'load_contents_async',
'load_contents_finish');
We estimate this will cover many common use cases.
Since this is a technology preview, we do not guarantee API stability with
the version coming in GNOME 3.32. These APIs are marked with underscores to
emphasize that they are not stable yet. Use them at your own risk.
- Closed bugs and merge requests:
* Added promisify to GJS GIO overrides [!225, Avi Zajac]
* Temporary fix for Gio.File.prototype [!226, Avi Zajac]

* Fix more "lost" GInterface properties [!223, Florian Müllner]
* Fix --enable-installed-tests when built from a tarball [!224, Simon
McVittie]
Version 1.53.90
---------------
- GJS now depends on SpiderMonkey 60 and requires a compiler capable of C++14.
- GJS includes a simple debugger now. It has basic stepping, breaking, and
printing commands, that work like GDB. Activate it by running the GJS console
interpreter with the -d or --debugger flag before the name of the JS program
on the command line.
- New API for programs that embed GJS: gjs_context_setup_debugger_console().
To integrate the debugger into programs that embed the GJS interpreter, call
this before executing the JS program.
- New JavaScript features! This version of GJS is based on SpiderMonkey 60, an
upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 52.
Here are the highlights of the new JavaScript features.
For more information, look them up on MDN or devdocs.io.
* New syntax
+ `for await (... of ...)` syntax is used for async iteration.
+ The rest operator is now supported in object destructuring: e.g.
`({a, b, ...cd} = {a: 1, b: 2, c: 3, d: 4});`
+ The spread operator is now supported in object literals: e.g.
`mergedObject = {...obj1, ...obj2};`
+ Generator methods can now be async, using the `async function*` syntax,
or `async* f() {...}` method shorthand.
+ It's now allowed to omit the variable binding from a catch statement, if
you don't need to access the thrown exception: `try {...} catch {}`
* New APIs
+ Promise.prototype.finally(), popular in many third-party Promise
libraries, is now available natively.
+ String.prototype.toLocaleLowerCase() and
String.prototype.toLocaleUpperCase() now take an optional locale or
array of locales.
+ Intl.PluralRules is now available.
+ Intl.NumberFormat.protoype.formatToParts() is now available.
+ Intl.Collator now has a caseFirst option.
+ Intl.DateTimeFormat now has an hourCycle option.
* New behaviour
+ There are a lot of minor behaviour changes as SpiderMonkey's JS
implementation conforms ever closer to ECMAScript standards. For complete
information, read the Firefox developer release notes:

https://developer.mozilla.org/en-US/Firefox/Releases/59#JavaScript
https://developer.mozilla.org/en-US/Firefox/Releases/60#JavaScript
* Backwards-incompatible changes
+ Conditional catch clauses have been removed, as they were a Mozilla
extension which will not be standardized. This requires some attention in
GJS programs, as previously we condoned code like `catch (e if
e.matches(Gio.IOError, Gio.IOError.EXISTS))` with a comment in
overrides/GLib.js, so it's likely this is used in several places.
+ The nonstandard `for each (... in ...)` loop was removed.
+ The nonstandard legacy lambda syntax (`function(x) x*x`) was removed.
+ The nonstandard Mozilla iteration protocol was removed, as well as
nonstandard Mozilla generators, including the Iterator and StopIteration
objects, and the Function.prototype.isGenerator() method.
+ Array comprehensions and generator comprehensions have been removed.
+ Several nonstandard methods were removed: ArrayBuffer.slice() (but not
the standard version, ArrayBuffer.prototype.slice()),
Date.prototype.toLocaleFormat(), Function.prototype.isGenerator(),
Object.prototype.watch(), and Object.prototype.unwatch().
- Many of the above backwards-incompatible changes can be caught by scanning
your source code using https://gitlab.gnome.org/ptomato/moz60tool, or
https://extensions.gnome.org/extension/1455/spidermonkey-60-migration-validator/
- Deprecation: the custom ByteArray is now discouraged. Instead of ByteArray,
use Javascript's native Uint8Array. The ByteArray module still contains
functions for converting between byte arrays, strings, and GLib.Bytes
instances.
The old ByteArray will continue to work as before, except that Uint8Array
will now be returned from introspected functions that previously returned a
ByteArray. To keep your old code working, change this:
let byteArray = functionThatReturnsByteArray();
to this:
let byteArray = new ByteArray.ByteArray(functionThatReturnsByteArray());
To port to the new code:
* ByteArray.ByteArray -> Uint8Array
* ByteArray.fromArray() -> Uint8Array.from()
* ByteArray.ByteArray.prototype.toString() -> ByteArray.toString()
* ByteArray.ByteArray.prototype.toGBytes() -> ByteArray.toGBytes()
* ByteArray.fromString(), ByteArray.fromGBytes() remain the same
* Unlike ByteArray, Uint8Array's length is fixed. Assigning an element past
the end of a ByteArray would lengthen the array. Now, it is ignored.
Instead use Uint8Array.of(), for example, this code:
let a = ByteArray.fromArray([97, 98, 99, 100]);
a[4] = 101;
should be replaced by this code:
let a = Uint8Array.from([97, 98, 99, 100]);
a = Uint8Array.of(...a, 101);
The length of the byte array must be set at creation time. This code will
not work anymore:
let a = new ByteArray.ByteArray();
a[0] = 255;
Instead, use "new Uint8Array(1)" to reserve the correct length.
