+2011-05-25: Version 3.3.10
+
+ Fixed calls of strict mode function with an implicit receiver.
+
+ Fixed fast handling of arrays to properly deal with changes to the
+ Object prototype (issue 1403).
+
+ Changed strict mode poison pill to be the same type error function
+ (issue 1387).
+
+ Fixed a debug crash in arguments object handling (issue 1227).
+
+ Fixed a bug in deoptimization on x64 (issue 1404).
+
+ Performance improvements and bug fixes on all platforms.
+
+
+2011-05-23: Version 3.3.9

+ arrays.
+
+ Fixed bug in handling of switch statements in the optimizing
+ compiler.
+
+
+2011-05-18: Version 3.3.8
+
+ Added MarkIndependent to the persistent handle API. Independent
+ handles are independent of all other persistent handles and can be
+ garbage collected more frequently.
+
+ Implemented the get trap for Harmony proxies. Proxies are enabled
+ with the --harmony-proxies flag.
+
+ Performance improvements and bug fixes on all platforms.
+

+
+ Updated MIPS infrastructure files.
+
+ Added method IsCallable for Object to the API.
+ Patch by Peter Varga.
+
+
+2011-05-09: Version 3.3.5
+
+ Fixed build on FreeBSD. Patch by Akinori MUSHA.
+
+ Added check that receiver is JSObject on API calls.
+
+ Implemented CallAsConstructor method for Object in the API (Issue 1348).
+ Patch by Peter Varga.
+
+ Added CallAsFunction method to the Object class in the API (Issue 1336).
+ Patch by Peter Varga.
+
+ Added per-isolate locking and unlocking.

+
+
+2011-05-04: Version 3.3.4
+
+ Implemented API to disallow code generation from strings for a context
+ (issue 1258).
+
+ Fixed bug with whitespaces in parseInt (issue 955).
+
+ Fixed bug with == comparison of Date objects (issue 1356).
+
+ Added GYP variables for ARM code generation:
+ v8_can_use_vfp_instructions, v8_can_use_unaligned_accesses
+ and v8_use_arm_eabi_hardfloat.
+
+
+2011-05-02: Version 3.3.3
+
+ Added support for generating Visual Studio solution and project files
+ using GYP.
+
+ Implemented support for ARM EABI calling convention variation where
+ floating-point arguments are passed in registers (hardfloat).
+
+ Added Object::HasOwnProperty() to the API.
+
+ Added support for compressing startup data to reduce binary size. This
+ includes build time support and an API for the embedder to decompress
+ the startup data before initializing V8.
+
+ Reduced the profiling hooks overhead from >400% to 25% when using
+ ll_prof.

-This directory contains Microsoft Visual Studio project files for including v8
-in a Visual Studio/Visual C++ Express solution. All these project files have
-been created for use with Microsoft Visual Studio 2005. They can however also
-be used in both Visual Studio 2008 and Visual C++ 2008 Express Edition. When
-using the project files in the 2008 editions minor upgrades to the files will
-be performed by Visual Studio.
+The Microsoft Visual Studio project files for including V8 in a Visual
+Studio/Visual C++ Express solution has been retired. If a Visual
+Studio project/solution is needed there is the option of using GYP to
+generate these. Please look in the build directory in the root of the
+V8 project. It contains the required infrastructure and a README.txt
+file explaining how to get started.
-v8_base.vcproj
---------------
-Base V8 library containing all the V8 code but no JavaScript library code.
+Generating Visual Studio projects using GYP is how the Chromium
+project integrated V8 into the Windows build.
-v8.vcproj
----------
-V8 library containing all the V8 and JavaScript library code embedded as source
-which is compiled as V8 is running.
-
-v8_mksnapshot.vcproj
---------------------
-Executable v8_mksnapshot.exe for building a heap snapshot from a running V8.
-
-v8_snapshot_cc.vcproj
----------------------
-Uses v8_mksnapshot.exe to generate snapshot.cc, which is used in
-v8_snapshot.vcproj.
-
-v8_snapshot.vcproj
-------------------
-V8 library containing all the V8 and JavaScript library code embedded as a heap
-snapshot instead of source to be compiled as V8 is running. Using this library
-provides significantly faster startup time than v8.vcproj.
-
-The property sheets common.vsprops, debug.vsprops and release.vsprops contains
-most of the configuration options and are inhireted by the project files
-described above. The location of the output directory used are defined in
-common.vsprops.
-
-With regard to Platform SDK version V8 has no specific requriments and builds
-with either what is supplied with Visual Studio 2005 or the latest Platform SDK
-from Microsoft.
-
-When adding these projects to a solution the following dependencies needs to be
-in place:
-
- v8.vcproj depends on v8_base.vcproj
- v8_mksnapshot.vcproj depends on v8.vcproj
- v8_snapshot_cc.vcproj depends on v8_mksnapshot.vcproj
- v8_snapshot.vcproj depends on v8_snapshot_cc.vcproj and v8_base.vcproj
-
-A project which uses V8 should then depend on v8_snapshot.vcproj.
-
-If V8 without snapshot if preferred only v8_base.vcproj and v8.vcproj are
-required and a project which uses V8 should depend on v8.vcproj.
-
-Two sample project files are available as well. These are v8_shell_sample.vcproj
-for building the sample in samples\shell.cc and v8_process_sample.vcproj for
-building the sample in samples\process.cc. Add either of these (or both) to a
-solution with v8_base, v8, v8_mksnapshot and v8_snapshot set up as described
-solution with v8_base, v8, v8_mksnapshot and v8_snapshot set up as described
-above and have them depend on v8_snapshot.
-
-Finally a sample Visual Studio solution file for is provided. This solution file
-includes the two sample projects together with the V8 projects and with the
-dependencies configured as described above.
-
-Python requirements
--------------------
-When using the Microsoft Visual Studio project files Python version 2.4 or later
-is required. Make sure that python.exe is on the path before running Visual
-Studio. The use of Python is in the command script js2c.cmd which is used in the
-Custom Build Step for v8natives.js in the v8.vcproj project.
+The main build system for V8 is still SCons, see the V8 wiki page
+http://code.google.com/p/v8/wiki/BuildingOnWindows for details.
