<li>Allow applications to specify transaction handles to the DB->associate method call, so secondary index creation can be grouped with other Berkeley DB calls in a single transaction. [#4185]</li>
<li>Add a new flag, DB_AUTO_COMMIT, that wraps single database
operations inside a transaction. This flag is supported by the
<li>Fix bugs that could cause hash recovery to drop core. [#4978]</li>
<li>Use access method flags instead of interface flags to check for read-only access to a hash database with an application-specified hash function. [#5121]</li>
<li>Fix a bug where a hash database allocation of a new set of buckets may be improperly recovered by catastrophic recovery if the transaction is split across log files and the beginning segment of the transaction is not included in the set of logs to be recovered. [#5942]</li>
<li>Fix a bug where aborting particular hash allocations could lead to a database on which the verifier would loop infinitely. [#5966]</li>
<li>Fix a bug where a memory allocation failure could result in a system hang. [#5988]</li>
<li>Remove nelem from the Hash access method statistics (the value was incorrect once items had been added or removed from the database). [#6101]</li>
<li>Fix a bug where a page allocated by an aborted transaction might not be placed on the free list by recovery, if the file holding the page was created as part of recovery, and a later page was part of a hash bucket allocation. [#6184]</li>
<li>Fix a bug where allocated pages could be improperly recovered on systems that require explicit zero-ing of filesystem pages. [#6534]</li>
<li>No longer return a copy of the key if the DB_SET_RANGE flag is specified. [#4470]</li>
<li>Fix a bug where DBcursor->c_get (with DB_MULTIPLE or DB_MULTIPLE_KEY specified) could fail on a Queue database if the record numbers had wrapped. [#6397]</li>
<li>C++ DbLock::put is replaced by DbEnv::lock_put to match the C and Java API change in Release 4.0. [#5170]</li>
<li>Declared destructors and methods within Db and DbEnv classes to be virtual, making subclassing safer. [#5264]</li>
<li>Fixed a bug where Dbt objects with no flags set would not be filled with data by some operations. [#5706]</li>
<li>Added DbDeadlockException, DbRunRecoveryException, and DbLockNotGrantedException classes to C++, and throw them accordingly. [#6134]</li>
<li>Added C++ methods to support remaining conversions between C++ classes and C structs where appropriate. In particular, DbTxn/DB_TXN conversions and DbMpoolFile/DB_MPOOLFILE were added. [#6278]</li>
<li>Fix a bug in DbEnv::~DbEnv() that could cause memory corruption if a DbEnv was deleted without being closed. [#6342]</li>
<li>Reordered C++ class declarations to avoid a GCC g++ warning about function inlining. [#6406]</li>
<li>Fix a bug in the DbEnv destructor that could cause memory corruption when an environment was destroyed without closing first. [#6342]</li>
<li>Change DbEnv and Db destructor behavior to close the handle if it was not already closed. [#6342]</li>
<li>Added check for system property "sleepycat.Berkeley DB.libfile" that can be used to specify a complete pathname for the JNI shared library. This is needed as a workaround on Mac OS X, where libtool cannot currently create a library with a .jnilib extension which is what the current JDK expects by default. [#5664]</li>
<li>Fixed handling of JVM out of memory conditions, when some JNI methods return NULL. When the JVM runs out of memory, calls should consistently fail with OutOfMemoryErrors. [#5995]</li>
<li>Added Dbt.get_object and Dbt.set_object convenience routines to the Java API to make using serialization easier. [#6113]</li>
<li>Fixed a bug that prevented Java's Db.set_feedback from working, fixed document for Java's Db.set_feedback, some callback methods were misnamed. [#6137]</li>
<li>Fix a NullPointerException in Db.finalize() if the database had been closed. [#6504]</li>
<li>Marked DbEnv constructor with "throws DbException". [#6342]</li>

<li>Fix a bug where an abort of a transaction could fail if there was no disk space for the log. [#5740]</li>
<li>Fix a bug where the checkpoint log-sequence-number could reference a nonexistent log record. [#5789]</li>
<li>Fix a bug where subtransactions which allocated pages from the filesystem and subsequently aborted could cause other pages allocated by sibling transactions to not be freed if the parent transaction then aborted. [#5903]</li>
<li>Fix a bug where transactions doing multiple updates to a queue database which spanned a checkpoint could be improperly handled by recovery. [#5898]</li>
<li>Fix a bug where the -p option could not be specified with the -R or -r options. [#5037]</li>
