    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:

        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]
      * context: use timeout with seconds to schedule a gc trigger [!239, Marco
        Trevisan]
