Other build commands of the form `make && make -C tiledb ` will have to be replaced by `make `. You can preview the effects of this change by configuring with CMake and passing the -DTILEDB_CMAKE_IDE=ON option. + +## Configuration changes + +* Implement consolidation memory budget variables. [#5011](https://github.com/TileDB-Inc/TileDB/pull/5011) + +## New features + +* Enable array open v2 and query v3 by default. [#4974](https://github.com/TileDB-Inc/TileDB/pull/4974) +* Add stats counter `memory_budget_exceeded` for when a query goes over budget.
