+How to build Qt for Symbian using the Linux makespec.
+
+Prerequisites:
+
+  - Working RVCT 2.2 native Linux compiler. The new publicly
+    available RVCT 4.0 compiler may work, but it hasn't been tested
+    yet.
+
+  - A working GnuPoc environment. See this page for details:
+    http://www.martin.st/symbian/
+    Download the latest version, unpack it and run the 'install_eka2_tools' script as
+    described in the last part under the EKA2 part. The part about the your own gcc
+    are not needed as we use the rvct compiler.
+    Make sure you do the part about Wine setup as well.
+
+  - Anderson Lizardo's patches for GnuPoc. Look for the
+    qt_s60_gnupoc_v10.patch on this page:
+    http://lizardo.wordpress.com/2009/09/24/installing-qt-for-s60-daily-snapshots-on-linux/
+    and carry out the instructions under point 8: Installing Open C.
+
+Compiling:
+
+ 1. First a few environment variables need to be set:
+
+        export RVCT22LIB=<rvct-dir>/lib/armlib
+        export EPOCROOT=<s60-root>
+        export PATH=$PATH:<s60-root>/epoc32/tools:<rvctInstallDir>/bin
+        export PATH=$PATH:<qt-root>/bin
+
+    Replace the s60-root with the installation directory of your SDK,
+    and the qt-root with the root of your Qt repository.
+    These are good candidates for putting in a script somewhere.
+
+ 2. Run configure. It needs a bit more switches than usual, so here's
+    the full line:
+
+        ./configure -developer-build -platform linux-g++ -xplatform \
+            symbian/linux-armcc -little-endian -host-little-endian \
+            -arch symbian
+
+ 3. Compile Qt
+
+        cd src
+        make
+
+    and then wait for a while.
+
+ 4. Package and install Qt
+
+        cd s60installs
+
+    Edit Qt_template.pkg and change the first 0x2xxxxxxx to
+    0xExxxxxxx. Then execute:
+
+        makesis Qt_template.pkg
+        signsis Qt_template.sis Qt_template.sisx selfsigned.cer selfsigned.key
+
+    Then put Qt_template.sisx on a memory card and install it from
+    the phone file manager.
+
+    Alternatively, you can use the runonphone tool found in the tools
+    directory of Qt. To build, this requires a separately configured
+    Qt installation for Linux, unfortunately. To use it, you also
+    need have App TRK running on the phone. At the time of writing,
+    only bleeding edge Linux kernels are able to autodetect the USB
+    serial port on the phone, but you can force detection by running:
+
+        modprobe usbserial vendor=0xXXXX product=0xXXXX
+
+    The XXXXs should be replaced with the two values listed for your
+    device when executing "lsusb". In most distributions, this will
+    lead to the creation of two devices: /dev/ttyUSB0 and
+    /dev/ttyUSB1. The latter is usually the one that App TRK responds
+    to. Then execute:
+
+        runonphone -p /dev/ttyUSB1 -s Qt_template.sisx dummy.exe
+
+    The dummy.exe argument is irrelevant, since we are not executing
+    anything yet.
+
+ 5. Compile some helloworld application (I leave the details to you
+    ;-)
+
+        qmake
+        make
+
+ 6. Package, install and run application.
+
+        makesis helloworld_template.pkg
+        signsis helloworld_template.sis helloworld_template.sisx \
+            <QTDIR>/src/s60installs/selfsigned.cer \
+            <QTDIR>/src/s60installs/selfsigned.key
+
+    Then either install by memory card, or install and run like this:
+
+        runonphone -p /dev/ttyUSB1 -s helloworld_template.sisx \
+            helloworld.exe
+
+ 7. Enjoy "hello world" on the phone!

+        WebKit needs a mechanism to catch stale HashMap entries
+
+        It is very difficult to catch stale pointers that are HashMap keys - since a pointer's hash
+        is just its value, it is very unlikely that any observable problem is reproducible.
+
+        This extends hash table consistency checks to check that pointers are referencing allocated
+        memory blocks, and makes it possible to invoke the checks explicitly (it is not feasible
+        to enable CHECK_HASHTABLE_CONSISTENCY by default, because that affects performance too much).
+
+        * wtf/HashMap.h: (WTF::::checkConsistency): Call through to HashTable implementation. We can
+        add similar calls to HashSet and HashCountedSet, but I haven't seen hard to debug problems
+        with those yet.
+

+        Make naming & behaviour of UString[Impl] methods more consistent.
+        https://bugs.webkit.org/show_bug.cgi?id=33702
+
+        UString::create() creates a copy of the UChar* passed, but UStringImpl::create() assumes
+        that it should assume ownership of the provided buffer (with UString::createNonCopying()
+        and UStringImpl::createCopying() providing the alternate behaviours).  Unify on create()
+        taking a copy of the provided buffer.  For non-copying cases, use the name 'adopt', and
+        make this method take a Vector<UChar>&.  For cases where non-copying construction was being
+        used, other than from a Vector<UChar>, change the code to allocate the storage along with
+        the UStringImpl using UStringImpl::createUninitialized().  (The adopt() method also more
+        closely matches that of WebCore::StringImpl).
+
+        Also, UString::createUninitialized() and UStringImpl::createUninitialized() have incompatible
+        behaviours, in that the UString form sets the provided UChar* to a null or non-null value to
+        indicate success or failure, but UStringImpl uses the returned PassRefPtr<UStringImpl> to
+        indicate when allocation has failed (potentially leaving the output Char* uninitialized).
+        This is also incompatible with WebCore::StringImpl's behaviour, in that
+        StringImpl::createUninitialized() will CRASH() if unable to allocate.  Some uses of
+        createUninitialized() in JSC are unsafe, since they do not test the result for null.
+        UStringImpl's indication is preferable, since we may want a successful call to set the result
+        buffer to 0 (specifically, StringImpl returns 0 for the buffer where createUninitialized()
+        returns the empty string, which seems reasonable to catch bugs early).  UString's method
+        cannot support UStringImpl's behaviour directly, since it returns an object rather than a
+        pointer.
+            - remove UString::createUninitialized(), replace with calls to UStringImpl::createUninitialized()
+            - create a UStringImpl::tryCreateUninitialized() form UStringImpl::createUninitialized(),
+              with current behaviour, make createUninitialized() crash on failure to allocate.
+            - make cases in JSC that do not check the result call createUninitialized(), and cases that do
+              check call tryCreateUninitialized().
+
+        Rename computedHash() to existingHash(), to bring this in line wih WebCore::StringImpl.

+        Three quick fixes to UStringImpl.
+            - The destroy() method can be switched back to a normal destructor; since we've switched
+              the way we protect static strings to be using an odd ref-count the destroy() won't abort.
+            - The cost() calculation logic was wrong.  If you have multiple JSStrings wrapping substrings
+              of a base string, they would each report the full cost of the base string to the heap.
+              Instead we should only be reporting once for the base string.
+            - Remove the overloaded new operator calling fastMalloc, replace this with a 'using' to pick
+              up the implementation from the parent class.

+
+        <rdar://problem/7296920> REGRESSION: WebKit fails to start PeaceKeeper benchmark
+
+        Test: fast/js/webcore-string-comparison.html
+
+        In r49365, some code was moved from JSString.cpp to JSString.h, and as a result, WebCore
+        got a way to directly instantiate JSStrings over DLL borders. Since vftable for JSString was
+        not exported, objects created from WebCore got a different vptr, and JavaScriptCore
+        optimizations that relied on vptr of all JSString objects being equal failed.
+
+        * config.h: Added a JS_EXPORTCLASS macro for exporting classes. It's currently the same as

+

+        conway benchmark spends half it's time in op_less (jump fusion fails)
+        https://bugs.webkit.org/show_bug.cgi?id=32190
+
+        <1% speedup on SunSpider and V8
+        2x speedup on "conway" benchmark
+        
+        Two optimizations:
+        1) Improve codegen for logical operators &&, || and ! in a condition context
+        
+        When generating code for combinations of &&, || and !, in a
+        condition context (i.e. in an if statement or loop condition), we
+        used to produce a value, and then separately jump based on its
+        truthiness. Now we pass the false and true targets in, and let the
+        logical operators generate jumps directly. This helps in four
+        ways:
+
+        a) Individual clauses of a short-circuit logical operator can now
+        jump directly to the then or else clause of an if statement (or to
+        the top or exit of a loop) instead of jumping to a jump.
+        
+        b) It used to be that jump fusion with the condition of the first
+        clause of a logical operator was inhibited, because the register
+        was ref'd to be used later, in the actual condition jump; this no
+        longer happens since a jump straight to the final target is
+        generated directly.
+
+        c) It used to be that jump fusion with the condition of the second
+        clause of a logical operator was inhibited, because there was a
+        jump target right after the second clause and before the actual
+        condition jump. But now it's no longer necessary for the first
+        clause to jump there so jump fusion is not blocked.
+
+        d) We avoid generating excess mov statements in some cases.
+        
+        As a concrete example this source:
+        
+        if (!((x < q && y < q) || (t < q && z < q))) {
+            // ...
+        }
+        
+        Used to generate this bytecode:
+        
+        [  34] less              r1, r-15, r-19
+        [  38] jfalse            r1, 7(->45)
+        [  41] less              r1, r-16, r-19
+        [  45] jtrue             r1, 14(->59)
+        [  48] less              r1, r-17, r-19
+        [  52] jfalse            r1, 7(->59)
+        [  55] less              r1, r-18, r-19
+        [  59] jtrue             r1, 17(->76)
+        
+        And now generates this bytecode (also taking advantage of the second optimization below):
+        
+        [  34] jnless            r-15, r-19, 8(->42)
+        [  38] jless             r-16, r-19, 26(->64)
+        [  42] jnless            r-17, r-19, 8(->50)
+        [  46] jless             r-18, r-19, 18(->64)
+        
+        Note the jump fusion and the fact that there's less jump
+        indirection - three of the four jumps go straight to the target
+        clause instead of indirecting through another jump.
+        
+        2) Implement jless opcode to take advantage of the above, since we'll now often generate
+        a less followed by a jtrue where fusion is not forbidden.

+        Part 1/3 of <rdar://problem/7377477> REGRESSION: Many web pages fail to render after interesting script runs in isolated world
+
+        Some clients of the JavaScriptCore API expect to be able to make callbacks over the JSC API,
+        and for this to automagically cause execution to take place in the world associated with the
+        global object associated with the ExecState (JSContextRef) passed.  However this is not how
+        things work - the world must be explicitly set within WebCore.
+
+        Making this work just for API calls to evaluate & call will be a far from perfect solution,
+        since direct (non-API) use of JSC still relies on WebCore setting the current world correctly.
+        A better solution would be to make this all work automagically all throughout WebCore, but this
+        will require more refactoring.
+
+        Since the API is in JSC but worlds only exist in WebCore, add callbacks on the JSGlobalData::ClientData
+        to allow it to update the current world on entry/exit via the JSC API.  This is temporary duck
+        tape, and should be removed once the current world no longer needs to be explicitly tracked.

-                  which to store the production's value. The callee must honor dst.
-
-    The dst argument provides for a crude form of copy propagation. For example,

-
-    becomes
-    
-        load r[x], 1

-    instead of 
-
-        load r0, 1
-        mov r[x], r0
-    
-    because the assignment node, "x =", passes r[x] as dst to the number node, "1".

+// (since appending to the string is likely more common) - and as such resolving

+Behavior and Animation syntax
+-----------------------------

+To make it more obvious that these are not regular value assignments a new "on"
+syntax has been introduced:

 matchProperties and matchTargets have been renamed back to properties and targets.
 The semantics are explained in the PropertyAnimation::properties documentation
 and the animation overview documentation.
 
-Behavior and Animation syntax
------------------------------
+Easing curves and their parameters are now specified via dot properties:
+* easing.type : enum
+* easing.amplitude : real
+* easing.overshoot : real
+* easing.period : real
+For example:
+PropertyAnimation { properties: "y"; easing.type: "InOutElastic"; easing.amplitude: 2.0; easing.period: 1.5 }
+
+C++ API
+-------
+QML_DEFINE_... definition macros, previously global macros, are replaced by
+qmlRegisterType registration functions, which must be called explicitly.
+C++ API users should also consider using the QmlExtensionPlugin (previously
+named QmlModulePlugin) as a cleaner mechanism for publishing libraries of QML
+types, or the upcoming application plugin features of the qmlviewer /
+qmlruntime / qml.
+
+QmlView
+-------
+The API of QmlView has been narrowed and its role as a convenience class
+reinforced.
+- remove addItem()
+- remove clearItems() - use 'delete root()'
+- remove reset()
+- resizeContent -> enum ResizeMode { SizeViewToRootObject, SizeRootObjectToView }
+- remove setQml(), qml()
+- rename setUrl(), ur() to setSource(), source()
+- root() -> rootObject(),  returns QGraphicsObject rather than QmlGraphicsItem
+- remove quit() signal -> use quit() signal of engine()
+- initialSize() signal removed
+- Added status() to determine status of the internal QmlComponent
+- removed execute() - setSource() will also execute the QML.
 
-Previously animations and behaviors could be "assigned" to properties like this:
-    Item { x: Behavior {}; y: NumberAnimation {} }
-To make it more obvious that these are not regular value assignments a new "on"
-syntax has been introduced:
-    Item { Behavior on x {}; NumberAnimation on y {} }
-Only the syntax has changed, the behavior is identical.

 The changes below are pre-4.6.0 release.

+\enum QDeclarativeEngine::ObjectOwnership
+
+Ownership controls whether or not QML automatically destroys the QObject when the object 
+is garbage collected by the JavaScript engine.  The two ownership options are:
+
+\list
+\o CppOwnership - The object is owned by C++ code, and will never be deleted by QML.  The
+JavaScript destroy() method cannot be used on objects with CppOwnership.  This option
+is similar to QScriptEngine::QtOwnership.
+
+\o JavaScriptOwnership - The object is owned by JavaScript.  When the object is returned to QML
+as the return value of a method call or property access, QML will delete the object if there
+are no remaining JavaScript references to it and it has no QObject::parent().  This option
+is similar to QScriptEngine::ScriptOwnership.
+\endlist
+
+Generally an application doesn't need to set an object's ownership explicitly.  QML uses
+a heuristic to set the default object ownership.  By default, an object that is created by
+QML has JavaScriptOwnership.  The exception to this are the root objects created by calling
+QDeclarativeCompnent::create() or QDeclarativeComponent::beginCreate() which have 
+CppOwnership by default.  The ownership of these root-level objects is considered to have
+been transfered to the C++ caller.
+
+Objects not-created by QML have CppOwnership by default.  The exception to this is objects
+returned from a C++ method call.  The ownership of these objects is passed to JavaScript.
+
+Calling setObjectOwnership() overrides the default ownership heuristic used by QML.

-    \qmlclass WorkerListModel QDeclarativeWorkerListModel
-    \brief The WorkerListModel element provides a threaded list model.
-
-    Use WorkerListModel together with WorkerScript to define a list model 
-    that is controlled by a separate thread. This is useful if list modification 
-    operations are synchronous and take some time: using WorkerListModel
-    moves these operations to a different thread and avoids blocking of the
-    main GUI thread.
-
-    The thread that creates the WorkerListModel can modify the model for any
-    initial set-up requirements. However, once the model has been modified by
-    the associated WorkerScript, the model can only be modified by that worker
-    script and becomes read-only to all other threads.
-    
-    Here is an example application that uses WorkerScript to append the
-    current time to a WorkerListModel:
-
-    \snippet examples/declarative/workerlistmodel/timedisplay.qml 0
-
-    The included file, \tt dataloader.js, looks like this:
-
-    \snippet examples/declarative/workerlistmodel/dataloader.js 0
-
-    The application's \tt Timer object periodically sends a message to the
-    worker script by calling \tt WorkerScript::sendMessage(). When this message
-    is received, \tt WorkerScript.onMessage() is invoked in
-    \tt dataloader.js, which appends the current time to the worker list
-    model.
-
-    Note that unlike ListModel, WorkerListModel does not have \tt move() and
-    \tt setProperty() methods.

     \brief The AnchorChanges element allows you to change the anchors of an item in a state.
 
-    AnchorChanges will 'inject' \c x, \c y, \c width, and \c height changes into the transition,
-    so you can animate them as you would normally changes to these properties:
+    In the following example we change the top and bottom anchors of an item:
+    \qml
+    AnchorChanges {
+        target: content; top: window.top; bottom: window.bottom
+    }
+    \endqml
+
+    AnchorChanges can be animated using AnchorAnimation.
     \qml
     //animate our anchor changes
-    NumberAnimation { targets: content; properties: "x,y,width,height" }
+    AnchorAnimation {}
     \endqml
 
     For more information on anchors see \l {anchor-layout}{Anchor Layouts}.
