+### New features

+- The CUDA/HIP pool uses fewer, and a user-controllable number of, cuBLAS/SOLVER and rocBLAS/SOLVER handles. This can significantly reduce GPU memory usage, especially on high core count systems. ([#1234](https://github.com/pika-org/pika/pull/1234))
+- The sender adaptor `transfer` has been renamed to `continues_on`, with a deprecation warning, to match the latest P2300 proposal. `transfer_just` and `transfer_when_all` have been deprecated. ([#1235](https://github.com/pika-org/pika/pull/1235))
