Version 1.2.1 (14 August 2008)

• add support for the libstdc++ parallel_mode (successor of MCSTL), new make targets: library_g++_pmode, tests_g++_pmode, clean_g++_pmode (requires g++ 4.3.2 or later)
• new stxxl file type stxxl::mem_file (for debugging purposes only), helps debugging with valgrind because no memory cell ever leaves valgrind's control
• properly destroy the singleton objects (block manager, disk queue threads, logger, stats, config, ...) at program exit
• fixed a bug (recursive locking) in recursive block allocation
• added a test program for recursive block allocation
• sensible dependencies for nmake (MSVC): only rebuild files as necessary
• improve performance of createdisks
• human-readable output for I/O stats
• replace hard coded min/max values by std::numeric_limits<>::min/max in examples
• fix a case where only half of the available memory was used during recursive merging
• verify stxxl::set_seed() functionality in tests
• remove stxxl disk files created from default configuration (no .stxxl file found) and other temporary files at program end
• stop using deprecated functions, switch to the replacements instead
