hamsterdb 0.4.8 - Release Notes

This release comes with AES encryption, zlib compression, a C++ API wrapper and minor bug fixes.

Environments now support a configurable number of databases; the default is 16, but files with a pagesize of 16kb can have up to 508 databases. See parameter HAM_PARAM_MAX_ENV_DATABASES for ham_env_create_ex.
Added a new function ham_env_get_database_names(), which returns all database names in an environment.
Implemented zlib-based compression; a new function was added: ham_enable_compression() (can be disabled by specifying --disable-compression as a ./configure option)
Implemented AES encryption; a new function was added: ham_env_enable_encryption() (can be disabled by specifying --disable-encryption as a ./configure option)
Added a C++ API file (include/ham/hamsterdb.hpp) and two samples: samples/db6.cpp and samples/env3.cpp.

Fixed bug in configure.in; on some systems, the call to getpagesize() was not declared correctly.
When moving a cursor through duplicates and the cache was exhausted, an assert was triggered.
(Win32) The parameters for memory mapped I/O did not create private copies and therefore the file could be damaged if an operation aborted

The default pagesize for unix databases is now 16kb, not 4kb; benchmarks show that this is the fastest option, but still results in small files.

(Win64/Debug) The routines for memory mapped I/O fail; as a work-around, use the Release libraries, which are working fine.
