GLib 是一个包含很多有用的 C 程序的开发包，例如树、哈希、列表等。GLib 之前是属于 GTK 工具包的一部分，现在独立出来成为单独项目。
GLib 2.36.0 改进记录：
- Signal handlers connected with g_signal_connect_object() are now automatically disconnected on target object destruction.
- GIO now has kqueue support for GFileMonitor (BSDs and Mac OS).
- UNIX signal sources now allow watching SIGUSR1 and SIGUSR2.
- In g_get_home_dir(), the $HOME variable is no longer ignored, and taken into consideration in favor of GECOS entries.
- GUnixFdSource was added as a new method to add file descriptors to the main loop.
- Further new APIs were added.
- Many bugs were fixed
