# ChangeLog file for GDK
# This file is updated with Maddlog
+* Tue Mar 26 2024 Sjoerd Mullender <sjo...@acm.org>
+- Made some changes to how BAT descriptors are allocated. They are now
+ allocated in bulk, meaning fewer malloc/free calls during processing.
+- Removed macro BBP_cache and its associated code. Checking whether a
+ BAT is cached (loaded in memory) can be done by checking the BBPLOADED
+ bit in the BBP_status value. Getting a pointer to the BAT descriptor
+ can be done by using BBP_desc.
+
* Tue Feb 6 2024 Sjoerd Mullender <sjo...@acm.org>
- The SQL transaction ID is no longer saved in the BBP.dir file.

# This file is updated with Maddlog
+* Thu Mar 28 2024 Sjoerd Mullender <sjo...@acm.org>
+- Threads have their own list of free bats. The list was not returned
+ to the system when a thread exited, meaning that the free bats that
+ were in the list would not be reused by any thread. This has been
+ fixed.
+
* Mon Mar 18 2024 Sjoerd Mullender <sjo...@acm.org>
- Fixed a couple of deadlock situations, one actually observed, one
never observed.
