    Release Notes: KEDR now works with kernel versions 3.10-3.15 (as of -rc4). It is now possible to make LeakCheck show the current set of allocated but not freed blocks at any time, and discard the collected data (if requested). LeakCheck now also shows information about the processes which allocated the leaked memory blocks. The call stack is now output for each simulated failure to simplify the analysis. Many fixes were made to the LeakCheck and Fault Simulation subsystem.

      Release Notes: The most significant enhancement in this version is support for Linux kernel versions 3.7 and 3.8. Several bugs were fixed.

        Release Notes: This release works on kernel versions 3.3-3.6 too. LeakCheck has been redesigned: the analysis engine has been separated from data collection. The API it provides allows you to use the memory leak detector in more cases than before. Handling of the information about signatures of the processed functions has been revisited. 12 more functions that allocate or deallocate memory are now processed, as are the functions kfree_rcu() expands to. Many fixes have been made in LeakCheck, fault simulation, and other subsystems.

          Release Notes: Handling of intercepted function calls has been revisited to allow doing several kinds of analysis at the same time. The components responsible for fault simulation are now decoupled from call monitoring facilities. Several enhancements and fixes have been applied to the trace capturing utility. The stack trace-related API has been revisited and simplified. Handling of allocations and frees in the memory leak detector is now deferred via a work queue. This allows you to significantly reduce the time spent with locks held.

            Release Notes: The build system was enhanced. It now allows building KEDR for a kernel different from the one running on the build machine. It is also possible to build KEDR for a different system (e.g. for Chromium OS, x86-generic).

              Release Notes: The tracing subsystem has been completely rewritten. A memory leak detector has been implemented. It is now possible to restrict fault simulation to particular areas in the target module. Several fixes have been made for KEDR to be able to work on the versions 2.6.37 and 2.6.38 of the Linux kernel. Call monitoring for 20 more functions is now supported. Support for fault simulation for many of these functions as well as for vmalloc() group has also been provided. The issues concerning parallel builds (make -j N) have been fixed.
