1.1.13

此版本修复了一个性能回归时，中止交易。中止期间，hamsterdb试图从事务日志重新创建的网页，即使他们没有在当前事务中的修改。这是正确的，但不必要的，造成性能下降。来源和预编译的Win32二进制文件可供下载。
This release fixes a performance regression when aborting Transactions. During abort, hamsterdb tried to re-create pages from the transaction log, even if they were not modified in the current Transaction. This was correct but unnecessary and caused a performance drop.
