### Berkeley DB 4.4.20 Change Log

### Changes since Berkeley DB 4.4.16:

1. Add support for Visual Studio 2005. [#13521]
2. Fix a bug with in-memory transaction logs when files wrapped around the buffer. [#13589]
3. Fix a bug where we needed to close replications open files during replication initialization. [#13623]
4. Fix a bug which could leave locks in the environment if database compaction was run in a transactional environment on a non-transactional database. This might have also have triggered deadlocks if the database was opened transactionally. [#13680]
5. Fix a bug where setting the DB_REGISTER flag could result in unnecessarily running recovery, or corruption of the registry file on Windows systems. [#13789]
6. Fix a bug in Database.compact that could cause JVM crashes or NullPointerException. [#13791]
7. Fix a bug that would cause a trap if an environment was opened specifying DB_REGISTER and the environment directory could not be found. [#13793]
8. Fix a buffer overflow bug when displaying process and thread IDs in the Berkeley DB statistics output. [#13796]
9. Fix a bug where if there is insufficient memory for a database key in a DBT configured to return a key value into user-specified memory, the cursor is moved forward to the next entry in the database, which can cause applications to skip key/data pairs. [#13815]
10. Fix a bug that could cause the loss of an update to a QUEUE database in a hot backup. [#13823]
11. Fix a bug where retrieval from a secondary index could result in a core dump. [#13843]
12. Fix a bug that could cause part of the free list to become unlinked if a btree compaction was rolled back due to a transaction abort. [#13891]
13. Fix a bug with in-memory logging that could cause a race condition to corrupt the logs. [#13919]
