Version 1.52.5

- 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.

- Closed bugs and merge requests:

  * Ensure not to miss the force_gc flag [#150, !132, Carlos Garnacho]
  * Make GC much more aggressive [#62, !50, Giovanni Campagna, Georges Basile
    Stavracas Neto, Philip Chimento]
  * Queue GC when a GObject reference is toggled down [#140, !114, !127, Georges
    Basile Stavracas Neto]
  * Reduce memory overhead of g_object_weak_ref() [#144, !122, Carlos Garnacho,
    Philip Chimento]
  * context: Defer and therefore batch forced GC runs [performance] [!236,
    Daniel van Vugt]

    Trevisan]
