1402===================
1403
1404Xpra:
1405  New features:
1406    -- Clipboard sharing (with full X semantics).
1407    -- Icon support.
1408    -- Support for raw TCP sockets. Insecure if you don't know what
1409       you are doing.
1410
1411  Bug fixes:
1412    -- Xvfb doesn't support mouse wheels, so they still don't work in
1413       xpra. But now xpra doesn't crash if you try.
1414    -- Running FSF Emacs under xpra no longer creates an infinite loop.
1415    -- The directory that xpra was launched from is now correctly
1416       saved in ~/.xpra/run-xpra.
1417    -- Work around PyGtk weirdness that caused the server and client
1418       to sometimes ignore control-C.
1419    -- The client correctly notices keyboard layout changes.
1420    -- The client no longer crashes on keymaps in which unnamed keys
1421       are bound to modifiers.
1422    -- Workarounds are included for several buggy versions of Pyrex.
1423
1424Wimpiggy:
1425  -- Assume that EWMH-style icons have non-premultiplied alpha.
1426
1427Other:
1428  -- Add copyright comments to all source files.
1429
1430v0.0.5 (2008-11-02)
1431===================
1432
1433This release primarily contains cleanups and bugfixes for xpra.
1434
1435General:
1436  -- Logging cleanup -- all logging now goes through the Python
1437     logging framework instead of using raw 'prints'.  By default
1438     debug logging is suppressed, but can be enabled in a fine- or
1439     coarse-grained way.
1440
1441Xpra:
1442  -- Protocol changes; v0.0.5 clients can only be used with v0.0.5
1443     servers, and vice-versa.  Use 'xpra upgrade' to upgrade old
1444     servers without losing your session state.
1445  -- Man page now included.
1446  Important bug fixes:
1447  -- Qt apps formerly could not receive keyboard input due to a focus
1448     handling bug; now fixed.
1449  -- Fedora's pygtk2 has mysterious local hacks that broke xpra;
1450     a workaround is now included.
1451  UI improvements:
1452  -- 'xpra attach ssh:machine' now works out-of-the-box even if xpra
1453     is not present in the remote machine's PATH, or requires
1454     PYTHONPATH tweaks, or whatever.  (The server does still need to
1455     be running on the remote machine, though, of course.)
1456  -- Commands that connect to a running xpra server ('attach', 'stop',
1457     etc.) now can generally be used without specifying the name of
1458     the server, assuming only one server is running.  (E.g., instead
1459     of 'xpra attach :10', you can use 'xpra attach'; ditto for remote
1460     hosts, you can now use plain 'xpra attach ssh:remote'.)
1461  -- Mouse scroll wheels now supported.
1462  -- 'xpra start' can now spawn child programs directly (--with-child)
1463     and exit automatically when these children have exited
1464     (--exit-with-children).
1465  Other:
1466  -- More robust strategy for handling window stacking order.
1467     (Side-effect: the xpra client no longer requires you to be using
1468     an EWMH-compliant window manager.)
1469  -- The xpra client no longer crashes when receiving an unknown key
1470     event (e.g. a multimedia key).
1471  -- Very brief transient windows (e.g., tooltips) no longer create
1472     persistent "litter" on the screen.
1473  -- Windows with non-empty X borders (e.g., xterm popup menus) are
1474     now handled properly.
1475  -- Withdrawn windows no longer reappear after 'xpra upgrade'.
1476
1477Wimpiggy:
1478  -- Do not segfault when querying the tree structure of destroyed
1479     windows.
1480  -- Other bugfixes.
1481
1482Parti:
1483  -- No changes.
1484
1485v0.0.4 (2008-04-04)
1486===================
1487
1488Xpra:
1489  -- Protocol changes break compatibility with 0.0.3, but:
1490  -- New command 'xpra upgrade', to restart/upgrade an xpra server
1491     without losing any client state.  (Won't work when upgrading from
1492     0.0.3, unfortunately, but you're covered going forward.)
1493  -- Fix bug that left stray busy-looping processes behind on server
1494     when using ssh connections.
1495  -- Export window class/instance hints (patch from Ethan Blanton).
1496  -- Hack to make backspace key work (full support for keyboard maps
1497     still TBD).
1498  -- Added discussion of xmove to README.xpra.
1499
1500Wimpiggy:
1501  -- Make compatible with current Pyrex releases (thanks to many
1502     people for reporting this).
1503  -- Work around X server bug #14648 (thanks to Ethan Blanton for help
1504     tracking this down).  This improves speed dramatically.
1505  -- Reverse-engineer X server lifetime rules for NameWindowPixmap,
1506     and handle it properly.  Also handle it lazily.  This fixes the
1507     bug where window contents stop updating.
1508  -- Avoid crashing when acknowledging damage against an
1509     already-closed window.
1510  -- Improve server extension checking (thanks to 'moreilcon' for the
1511     report).
1512  -- Remove spurious (and harmless) assertion messages when a window
1513     closes.
1514  -- Make manager selection handling fully ICCCM-compliant (in
1515     particular, we now pause properly while waiting for a previous
1516     window manager to exit).
1517  -- Make algorithm for classifying unmapped client windows fully
1518     correct.
1519  -- Reduce required version of Composite extension to 0.2.
1520
1521Parti:
1522  -- Remove a stale import that caused a crash at runtime (thanks to
1523     'astronouth7303' for the report).
1524
1525General:
1526  -- Error out build with useful error message if required packages
1527     are missing.
1528
1529Parti 0.0.3 (2008-02-20)
1530========================
1531
1532Massive refactoring occurred for this release.
1533
1534wimpiggy: The WM backend parts of Parti have been split off into a
1535separate package known as wimpiggy.  As compared to the corresponding
1536code in 0.0.2, wimpiggy 0.0.3 adds:
1537  -- Compositing support
1538  -- Model/view separation for client windows (based on compositing
1539     support)
1540  -- Improved client hint support, including icon handling, strut
1541     handling, and more correct geometry handling.
1542  -- Keybinding support
1543  -- Event dispatching that doesn't leak memory
1544  -- Better interaction with already running window managers (i.e., a
1545     --replace switch as seen in metacity etc.)
1546
1547parti: This package will eventually become the real window manager,
1548but for now is essentially a testbed for wimpiggy.
1549
1550xpra: This is a new, independent program dependent on wimpiggy (which
1551is why wimpiggy had to be split out).  It implements 'screen for X' --
1552letting one run applications remotely that can be detached and then
1553re-attached without losing state.  This is the first release, but
1554while not perfect, it is substantially usable.
1555
1556general: The test runner was hacked to share a single X/D-Bus session
1557across multiple tests.  This speeds up the test suite by a factor of
1558~3, but seems to be buggy and fragile and may be reverted in the
1559future.
1560
1561Parti 0.0.2 (2007-10-26)
1562========================
1563
1564This release adds a mostly comprehensive test suite, plus fixes a lot
1565of bugs.  Still only useful for experimentation and hacking.
1566
1567'python setup.py sdist' sort of works now.
1568
1569Parti 0.0.1 (2007-08-10)
1570========================
1571
1572Initial release.
1573
1574Contains basic window manager functionality, including a fair amount
1575of compliance to ICCCM/EWMH, focus handling, etc., and doesn't seem to
1576crash in basic testing.
1577
1578Doesn't do much useful with this; only a simple placeholder layout
1579manager is included, and only skeleton of virtual desktop support is
1580yet written.
