release 2.1.6

[Christoph Rupp]

Hi,

hamsterdb 2.1.6 is released.

Changes include a bugfix for issue #30, which is a regression that appeared in 2.1.5. The file size grew way too much whenever the cache was purged. This mostly happens when the cache size is very small.

Also, the physical write ahead-log and the logical journal were merged, and the files are now buffered. If you use Transactions or Recovery then performance will increase.

Best regards
Christoph
