-
-* Security fixes:
- * Fix CVE-2007-1667: Multiple integer overflows in the XGetPixel() and
- XInitImage() functions.
- * 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
- lock (as in XLockDisplay) before calling exit(3). This blocks Xlib calls
- from threads other than the one calling exit(3) while still allowing the
- exit handlers to call Xlib.
-
-* Xlib/XCB: Avoid re-crashing after _XIOError.
-
-* Xlib/XCB: Only remove pending_requests when there are provably no more responses.
-
-* 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.
-
-* Manpage fixes:
- * Add man pages for XKB APIs.
- (Volunteer needed to convert prototypes in man pages to ANSI C style...)
- * Protect C comments and #defines in XKB man pages from being mangled by cpp
- * Fix typo in nroff macro in XkbAddGeomOverlayKey.man
- * Bug #9695: Fixed a few argument types in the XOpenIM manpage.
- * Markup tweak for XOpenIM.
- * Bug #9696: refer to XDefineCursor() instead of XDefineCusor().
- * Bug #9697: Fixed documentation of XVisualInfo struct. The "depth" member
- was said to be unsigned int, but it's signed.
-
-* nls fixes:
- * Update el_GR.UTF-8/Compose.pre to match changes in xkeyboard-config cvs.
- * For nls/*.pre, allow people to comment lines by starting them with '##'.
-
-* Build system fixes:
- * Add autogen.sh to EXTRA_DIST.
- * Makefile.am: make ChangeLog hook safer
- * Don't distribute the configure-generated XlibConf.h in tarballs.

-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
