Are you talking about Glib? yes, there are many changes since 2.32
(for now stable version is 2.34), from high level view, the changes
such as new thread creation functions, thread reference counting
functions, thread synchronization tools, etc. and many other functions
and macros has been removed.

In 2.32 and above to create a thread you will use the new
g_thread_new() or the g_thread_try_new() (previously with
g_thread_create()), to create synchronization tools for example a
rwlock then you call g_rwlock_init (previously g_rwlock_new() or
G_STATIC_RWLOCK_INIT), call g_thread_unref() after you finish with the
thread.

I don't understand why you call g_main_context_invoke() here but If
you want to call GTK+ functions from your thread, the safe method is
to wrap the functions to a GSourceFunc and call it with g_idle_add()
or g_idle_add_full() (from your thread function).
