+Notes about GLib 2.6.0
+======================
+
+* GLib 2.6 introduces the concept of 'GLib filename encoding', which is the
+ on-disk encoding on Unix, but UTF-8 on Windows. All GLib functions
+ returning or accepting pathnames have been changed to expect
+ filenames in this encoding, and the common POSIX functions dealing
+ with pathnames have been wrapped. These wrappers are declared in the
+ header <glib/gstdio.h> which must be included explicitly; it is not
+ included through <glib.h>.
+
+ On current (NT-based) Windows versions, where the on-disk file names
+ are Unicode, these wrappers use the wide-character API in the C
+ library. Thus applications can handle file names containing any
+ Unicode characters through GLib's own API and its POSIX wrappers,
+ not just file names restricted to characters in the system codepage.
+
+ To keep binary compatibility with applications compiled against
+ older versions of GLib, the Windows DLL still provides entry points
+ with the old semantics using the old names, and applications
+ compiled against GLib 2.6 will actually use new names for the
+ functions. This is transparent to the programmer.
+
+ When compiling against GLib 2.6, applications intended to be
+ portable to Windows must take the UTF-8 file name encoding into
+ consideration, and use the gstdio wrappers to access files whose
+ names have been constructed from strings returned from GLib.
+
+* Likewise, g_get_user_name() and g_get_real_name() have been changed
+ to return UTF-8 on Windows, while keeping the old semantics for
+ applications compiled against older versions of GLib.
+
+* The GLib uses an '_' prefix to indicate private symbols that
+ must not be used by applications. On some platforms, symbols beginning
+ with prefixes such as _g will be exported from the library, on others not.
+ In no case can applications use these private symbols. In addition to that,
+ GLib+ 2.6 makes several symbols private which were not in any installed
+ header files and were never intended to be exported.
+
+* To reduce code size and improve efficiency, GLib, when compiled
+ with the GNU toolchain, has separate internal and external entry
+ points for exported functions. The internal names, which begin with
+ IA__, may be seen when debugging a GLib program.
+
+* On Windows, GLib no longer opens a console window when printing
+ warning messages if stdout or stderr are invalid, as they are in
+ "Windows subsystem" (GUI) applications. Simply redirect stdout or
+ stderr if you need to see them.
+
+* The child watch functionality tends to reveal a bug in many
+ thread implementations (in particular the older LinuxThreads
+ implementation on Linux) where it's not possible to call waitpid()
+ for a child created in a different thread. For this reason, for
+ maximum portability, you should structure your code to fork all
+ child processes that you want to wait for from the main thread.
+
+* A problem was recently discovered with g_signal_connect_object();
+ it doesn't actually disconnect the signal handler once the object being
+ connected to dies, just disables it. See the API docs for the function
+ for further details and the correct workaround that will continue to
+ work with future versions of GLib.
