Fixed compiler error related to inline assembly on gcc 4.8.x
Fixed bug when ups_cursor_overwrite would overwrite a transactional record instead of the (correct) btree record
Fixed several bugs in the duplicate key consolidation
issue #80: fixed streamvbyte compilation for c++11
issue #79: fixed crc32 failure when reusing deleted blobs spanning multiple pages
Fixed a bug when recovering duplicates that were inserted with one of the UPS_DUPLICATE_INSERT_* flags
Minor improvements for the journalling performance
Fixed compilation issues w/ gcc 6.2.1 (Thanks, Roel Brook)

Hamsterdb 2.1.1 released Jul 3, 2013 (New Release)

· Removed internal (but exported) functions ham_env_get_device, ham_env_set_device
· Improved integration of tcmalloc, removed ham_env_set_allocator
· A small semantic change: when retrieving partial records with ham_db_find or ham_cursor_find, the partial size is now stored in record.partial_size and the original size is stored in record.size. Previously, the partial size was stored in record.size.
· Merged various MacOS related fixes
· Fixed build if remote functionality is disabled (i.e. because protobuffer or libcurl is missing)

Hamsterdb 2.1.0 released Mar 5, 2013 (New Release)

Semantic Changes:
· Extended keys are now disabled by default; use HAM_ENABLE_EXTENDED_KEYS to enable them
· Creating/Opening an Environment is now mandatory; ham_open/ham_create were removed
· ham_new, ham_delete, ham_env_new, ham_env_delete were removed as well and are no longer required

Renamed Macros/Functions:
· C++ API: renamed the namespace from "ham" to "hamsterdb"
· ham_check_integrity -> ham_db_check_integrity
· ham_get_error -> ham_db_get_error
· ham_set_prefix_compare_func -> ham_db_set_prefix_compare_func
· ham_set_compare_func -> ham_db_set_compare_func
· ham_find -> ham_db_find
· ham_insert -> ham_db_insert
· ham_erase -> ham_db_erase
· ham_get_key_count -> ham_db_get_key_count
· ham_get_parameter -> ham_db_get_parameter
· ham_get_env -> ham_db_get_env
· ham_close -> ham_db_close

Hamsterdb 2.0.5 released Dec 6, 2012 (New Release)

Bug fixes:
· (dotnet) Fixed invalid memory access when using Parameter[] in env.CreateDatabase or env.OpenDatabase (Thanks, Jason)
· Issue 16: Fixed the recovery process for temporary Transactions

Other Changes:
· Removed HAM_PARAM_GET_STATISTICS; ham/hamsterdb_stats.h is no longer public, and the functions are no longer exported
· The internal C++ implementation was moved into namespace "ham" in order to avoid conflicts with other applications
· Performance improvements when using record number databases with recovery
· Win32 files are now created with FILE_ATTRIBUTE_NOT_CONTENT_INDEXED

Hamsterdb 2.0.4 released Sep 3, 2012 (New Release)

New Features


Fixed linker error when libboost_thread-mt.lib is installed
Fixed compilation error in OSX Lion
Other Changes

(java) Fixed race condition when closing Cursors (thanks, Mark S.)
Fixed issue 8: Fixed data corruption when retrieving a record returns HAM_BLOB_NOT_FOUND (thanks, Artem)
Fixed several bugs (mainly related to misplaced asserts) when performing recovery
Fixed crash when reusing a page from the cache that was not correctly initialized (thanks, Jason)
Fixed crash when HAM_ENABLE_RECOVERY w/o HAM_ENABLE_TRANSACTIONS (thanks, Peter)
Fixed issue 7: approximate matching did not return the correct key (thanks, Artem)
Fixed MacOS compilation problem (thanks, Jason P.)

Hamsterdb 2.0.2 released May 7, 2012 (New Release)

· Fixed a buffer overrun in the freelist
· hamsterdb is now thread safe. The boost c++ library is now required for building
· enabled approx matching for ham_cursor_find
· hamsterdb is now thread-safe
· When using Transactions, the key->data and record->data pointers will point into memory managed by the Transaction, not by the Database

Hamsterdb 2.0.0 released Jan 25, 2012 (New Release)

· Changed interface ham_txn_begin, also for Wrapper APIs

· When recovery or transactions are enabled then for most operations the physical log is no longer required; this reduces I/O and improves performance

· dotnet: integrated the files, updated the interface
· java: integrated the files, updated the interface
· wince: moved to /contrib directory

Hamsterdb 1.1.8 released Dec 8, 2010 (New Release)

· configure.in will no longer overwrite -Ox flags; the default compilation option is now -O2
· bugfix with HAM_DIRECT_ACCESS and cursors which insert duplicates at the
· beginning of the duplicate list; if record size is
