 Change Log for Releases
 ==============================
 
+## 004.next
+* New Features
+  - X4xx: Extended existing GPIO SPI support beyond 32 bits, to 64-bit transfers.
+  - FPGA tools: Added support for DCP files as source inputs.
+  - example: `benchmark_rate` can optionally wait for TX end-of-burst
+    acknowledgements with a configurable timeout (`--tx_eob_ack_timeout`).
+* Bug Fixes
+  - X4xx: Corrected the RFDC NCO reset sequence and adjusted its default wait time.
+  - B3xx: Corrected the GPS timepulse polarity.
+  - B2xx: Added missing firmware descriptors for B200-mini and B205-mini variants.
+  - MultiUSRP API: RFNoC-backed `set_master_clock_rate()` now updates connected
+    DDC/DUC rates while preserving the requested TX/RX sample rates.
+  - FPGA DSP: Fixed halfband temporal decimation.
+  - FPGA DSP: Improved resource usage, CIC flow-control and reset handling.
+  - RFNoC: The image builder now handles GRC builds with empty parameters and
+    correctly processes the `--CHECK` image-build option.
+  - MPM: Improved X4xx device discovery responsiveness by caching transport
+    information and refreshing it when network interfaces or addresses change.
+  - MPM: RPC requests made during a device reset now return a transient
+    `UNAVAILABLE` status so clients can retry.
+* API Changes
+  - Added explicit 32-bit and 64-bit SPI transaction methods to the C++ API
+    and RFNoC Python bindings. 64-bit transactions are only available on some
+    devices.
+* FPGA
+  - Updated FPGA build flow and test benches to Vivado 2025.2.
