[gjs] Created tag 1.65.90

[Philip Chimento <pchimento src gnome org>]

The unsigned tag '1.65.90' was created.

Tagger: Philip Chimento <philip chimento gmail com>
Date: 1597203901 -0700

    Version 1.65.90
    
    - GJS now has an optional, Linux-only, dependency on libsysprof-capture-4
      instead of libsysprof-capture-3 for the profiler functionality.
    
    - New API: gjs_coverage_enable() allows the collection of code coverage metrics.
      If you are using GjsCoverage, it is now required to call gjs_coverage_enable()
      before you create the first GjsContext. Previously this was not necessary, but
      due to changes in SpiderMonkey 78 you must now indicate in advance if you want
      to collect code coverage metrics.
    
    - New JavaScript features! This version of GJS is based on SpiderMonkey 78, an
      upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 68.
      Here are the highlights of the new JavaScript features.
      For more information, look them up on MDN or devdocs.io.
    
      * New language features
        + A new regular expression engine, supporting lookbehind and named capture
          groups, among other things
    
      * New syntax
        + The ?? operator ("nullish coalescing operator") is now supported
        + The ?. operator ("optional chaining operator") is now supported
        + Public static class fields are now supported
        + Separators in numeric literals are now supported: for example, 1_000_000
    
      * New APIs
        + String.replaceAll() for replacing all instances of a string inside another
          string
        + Promise.allSettled() for awaiting until all Promises in an array have
          either fulfilled or rejected
        + Intl.Locale
        + Intl.ListFormat
        + Intl.RelativeTimeFormat.formatToParts()
    
      * 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/78#JavaScript
    
      * Backwards-incompatible changes
        + The Object.toSource() method has been removed
        + The uneval() global function has been removed
        + A leading zero is now never allowed for BigInt literals, making 08n and
          09n invalid similar to the existing error when legacy octal numbers like
          07n are used
        + The Function.caller property now has the value of null if the caller is a
          strict, async, or generator function, instead of throwing a TypeError
    
    - Backwards-incompatible change: Paths specified on the command line with
      the --coverage-prefix argument, are now always interpreted as paths. If they
      are relative paths, they will be resolved relative to the current working
      directory. In previous versions, they would be treated as string prefixes,
      which led to unexpected behaviour when the path of the script was absolute
      and the coverage prefix relative, or vice versa.
