A tool upgrade from v4.1 to v4.2. Contains some bug fixes and enhancements, for example: XML format reporting enhanced, better analysis of inline methods in class/struct declarations, more robust handling of conditional compilation blocks in the source files to be measured, many improvements in the HTML format reporting, improved CMT++ GUI (at Windows), introduced Visual Studio 2005 IDE integration. More cmtdesc.html.

The add-on package is extended so that the code under test can be also C code. Previously only C++ code was supported. The procedures to do builds with CTC++ are adjusted to the main CTC++ v6.4 level (use of 'ctcwrap'). Some optimisations in the run-time behavior are implemented. More ctcsymbi.html.

Introduced 'ctcwrap' capability also on Windows platform. It facilitates extremely simple way to do "ctc-builds" with existing makefiles and other build arrangements. The IDE integrations to Visual Studio .NET 2003 and to Visual Studio 2005 are  renewed, making the usage simpler and more powerful.  Introduced a "power-user capability" to aggregate coverage data in a controlled way of separate/independent "ctc-builds" and their test sessions. Some bugs have been fixed. Among them is strengthening CTC++ capability to instrument Visual C++ code, which contains "attributes" (certain Microsoft extensions that are written in brackets). More ctcdesc.html.

Optimizations at the target run-time behavior. Introduced model implementations for the low-level data transfer routines. Clarified and improved the documentation. More hota.

The CTC++ for Symbian Target Devices add-on v3.1 package has been upgraded to work on Symbian OS v9.x (EKA2 kernel) based devices. See the description of this add-on package. Target support for the previous Symbian OS level upto v8 (EKA1 kernel) has been discontinued. Support for the EPOC emulator (Symbian OS before and after v9) use in the CTC++/Windows version continues unchanged.

Various enhancements and bug fixes on some demanding use cases. Introduced Visual Studio 2005 IDE integration. The HTML report is enhanced  (report sorting, directory level summaries, etc.). Introduced 'ctcwrap' integration on Unix makefiles and other commands.
