+
+* Security fixes:
+ * Fix CVE-2007-1667: Multiple integer overflows in the XGetPixel() and

+ * Bug #9279: Fixed a file descriptor leak.
+
+* Xlib/XCB: Ensure _XReadEvents reads at least one new event and blocks for
+ exactly one event. Large performance improvement for XIfEvent and similar.
+
+* Hold XCB's Xlib lock even when only the user lock (XLockDisplay) is held.
+ An Xlib client can query Display state, such as with NextRequest, while it
+ holds only the Xlib user lock (between XLockDisplay and XUnlockDisplay), so
+ XCB requests in other threads should be blocked when the Xlib user lock is
+ held. We acquire the lock even when XInitThreads was not called, so that
+ pure XCB code can use multiple threads even in an otherwise single-threaded
+ Xlib application.
+
+* Allow re-entrant Xlib calls from _XIOError.
+ Some libraries try to clean up X resources from atexit handlers, _fini, or
+ C++ destructors. To make these work, downgrade the Display lock to a user

+
+* For NetBSD, define XTHREADLIB and XTHREAD_CFLAGS.
+
+* Bug #7703: Fixed XSetSizeHints() et al wrt use of uninitialized data.
+ Now only those fields of the respective hint struct are set that
+ are actually valid in the input data.
+
+* Bug #10292: Fixed a memory leak related to XOpenDisplay() in the XCB code.
+
+* Bug #7713: Initialize all of the event's fields before sending it.
+
+* Bug #10562: Define _GNU_SOURCE on glibc systems.
+
+* Use unistd.h to get getresuid() and friends, now that we have _GNU_SOURCE
+ defined.
+
+* Switched function definitions from K&R to ANSI style.
+
+* Many constness fixes.
+
+* Fixed a few warnings.
+
+* Fix 64bit issues with reallocation.

+
+Version 1.1.1 - 2006-11-30
+
+The "xcompmgr is hard, let's go releasing" release
+
+* Fix Bug #9154 and friends, to unbreak xcompmgr:
+ Always process an event for _XReadEvents, even if an error occurs.
+ Previously, process_responses (in the wait_for_first_event case called
+ from _XReadEvents) considered any return from xcb_wait_for_event
+ sufficient to think it had processed an event. If xcb_wait_for_event
+ returned an error, and no more events occurred before process_responses
+ called xcb_poll_for_event, process_responses would try to return with
+ dpy->head NULL, and would fail an assertion for the _XReadEvents
+ postcondition. Now, process_responses continues using xcb_wait_for_event
+ until it gets an event.
+
+* Bug #9153: Fix access to freed memory.
+ The fix for bug #8622 introduced a smaller bug where _XReply would
+ read memory shortly after freeing it. This patch caches the needed
+ value in a stack-allocated variable before the heap-allocated memory
+ is freed.
+
+* libx11 doesn't use inputproto in public headers; don't require it in x11.pc.
+ Based on a Debian patch.
+
+* Debian bug #354315: Clarify return value in XGetWindowAttributes man page.
+ Patch by Debian user Ross Combs.
+
+
+Version 1.1 - 2006-11-23
+
+* Add note in man-page that XListFontsWithInfo is not thread-safe. _XReply
+ drops the Display lock, so the value of dpy->request may change before
+ _XReply is called again. Jamey Sharp discovered this by inspection a few
+ years ago.
+
+* Fix Bug #8622, by fixing the response processing order for threaded apps.
+ process_responses (the common code for _XReply, _XReadEvents, and
+ _XEventsQueued) now handles responses in order, by adding condition variables
+ to the list of outstanding requests in dpy->xcb->pending_requests, and
+ blocking on them when those requests should get processed, to allow _XReply
+ to process them; if actually called from _XReply, it returns when _XReply's
+ request should get processed. _XReply broadcasts on its condition variable
+ after it has read its reply and re-acquired the display lock.
+
+* Don't hold the display lock around callbacks to the application. This avoids
+ recursive locking of the display lock (which triggers an XCB locking
+ assertion), particularly with emacs.
+
+* Add xcb-xlib dependency to x11.pc when built against XCB.
+
+* Allocate the right amount of memory for dpy->lock_fns. Fixes a crash on
+ startup with gdk.
+
+
+Version 1.1 RC2 - 2006-11-02
+
+Benno Schulenberg:
+ nls: remove duplicate compose entries (bug #2286)
+ nls: remove shadowed compose entries (bug #2286)
+ nls (en_US): remove long compositions that override shorter (bug #2286)
+
+Caolan McNamara:
+ XKB geometry: fix leaks in GetKeyboardByName (bug #8099)
+
+David Nusinow:
+ Dynamically generate internal manpage section using __libmanpagesuffix__ so that it actually matches the section if you don't use 3X11
+
+Jamey Sharp:
+ Add correct Display locking to XKB functions.
+ XKB bugfix: SyncHandle must be called after UnlockDisplay, not before.
+ XCB: check for and handle I/O errors in _XGetXCBBuffer.
+
+Matthias Hopf:
+ Fix double open of compose file.
+
+
+Version 1.1 RC1 - 2006-10-06
+
+This release includes the Xlib/XCB work, which uses XCB as the Xlib transport
+layer, and allows a client to use both Xlib and XCB on the same connection.
+This allows clients to transition from Xlib to XCB incrementally.
+
+Clients which link only to libX11, and do not use XCB, should not notice any
+differences in this release. Clients desiring XCB interoperability should
+additionally #include <X11/Xlib-xcb.h>, link to libX11-xcb, use
+XGetXCBConnection(dpy) to obtain the underlying XCB connection, and then use
+XCB functions directly on that connection.
+
+Note that while a client can issue requests and handle their replies or errors
+with either Xlib or XCB, only one can own and handle the event queue. By
+default, Xlib must own the event queue, for compatibility with legacy Xlib
+clients. Clients can use the function XSetEventQueueOwner immediately after
+XOpenDisplay to let XCB own the event queue instead. Clients may not call
+this function after processing any responses, as this will potentially lose
+responses.
+
+We expect to have an RC2 release corresponding to the Xorg RC2 schedule, which
+should include additional internal architecture enhancements, but no
+user-visible changes. 1.0 final should match RC2.
+
+Other smaller changes in this release:
+* correct ChangeLog generation
+* support running lint and sparse
+* Autoconf 2.60
+* fix man page for XUrgencyHint
+* improve man pages for XGrabButton, XGrabKey, XGetWindowProperty
+* new locales: as_IN.UTF-8, kn_IN.UTF-8, ml_IN.UTF-8, or_IN.UTF-8,
+ te_IN.UTF-8, ur_IN.UTF-8
+* on systems with both UNIXCONN and LOCALCONN, try unix if local fails
+* fix sparse warnings
+* ansify static functions
