 Change Log for Releases
 ==============================
 
+## 004.007.000.000
+* Highlights / Main Changes
+  - Major updates to rfnoc_image_builder (a98ce26). This change adds support for
+    defining transport adapters in the image builder YAML files, adding custom
+    modules, and more.
+  - Updated embedded OS on file system images for E3xx, N3xx, and X4xx devices
+    to Yocto 4.0 (kirkstone).
+* New Features
+  - General
+    - Allow installing only Python-based utilities (e.g., rfnoc_image_builder)
+      by adding the ENABLE_PYMOD_UTILS option to CMake.
+    - Added ability to query dot representation of RFNoC graph
+  - Python support
+    - Added DRAMReceiver class and amend rx_to_file.py example to use new class.
+      This supplements the DRAMTransmitter class and simplifies using the DRAM-backed 
+      RFNoC replay block to when signal bandwidth exceeds available streaming bandwidth.
+  - CMake
+    - We now search for a system version of Pybind11 before falling back to the
+      bundled version. The system version is preferred, and the bundled version
+      may be removed in a future release.
+   - RFNoC
+    - Image builder: Major update, which adds support for defining transport
+      adapters in the image builder YAML files, adding custom modules, choosing
+      custom directories for build, IP, and intermediate files, building IP
+      only, saving Vivado projects, and more. Image core YAML files created with
+      this version are not compatible with previous versions, and vice versa!
+    - Added support for defining custom register spaces in RFNoC blocks.
+    - Added license checking subsystem. This allows creating RFNoC blocks that
+      require a license key to operate.
+    - Add device DNA feature for X310, X410, X440. This allows reading back the
+      FPGA's DNA, which is a unique identifier.
+  - X440
+    - Added new guided log info mode to provide more information about the Nyquist 
+      zone in which the chosen frequency is located. These additional info logs
+      are enabled by default. For disabling the guided mode, add the entry 
+      `guided_mode=false` to the UHD config file in the "Global" section.
+  - Examples
+    - rfnoc-example now also generates Python bindings for OOT block control functions.
+* Dependencies changes
+  - Increase minimum required version
+    - Python to 3.7.0
+    - Pybind11 to 2.7.0
+* Bug Fixes
+  - General UHD
+    - Fix issue with undefined HOME or XDG_CONFIG_HOME
+    - Fix compilation error with boost 1.85.0 (closed issue 740)
+    - Fixed cmake find_library for UHD to fail if the library is not found 
+    - Fixed setters for ALL_CHANS in multi_usrp
+    - Demote safe call logging to warning
+    - Fix outstanding clang-format issues
+    - fix compiling with gcc 13.2
+  - Python support
+    - YAML files are now listed as part of the package
+    - Fix setting start_time having no effect
+  - RFNoC
+    - Add EOB to source port of null_src_sink block
+    - Fix RFNoC graph action queue lockup on action exceptions
+    - FIR filters now uses newer IP revisions
+    - Reverse FIR filter coefficients now get embedded in DSPE48
+  - B2xx
+    - Fixed FRAC2 calculation (closed issue 684). 
+    - Fix DC truncation bias by adding rounding to DDC chain
+  - X310
+    - Fix warning about duplicate reg
+    - ubx
+      - update ubx xcvr mode options
+      - write output power to correct LO
+      - Fix width of gain register
+  - MPM
+    - Deactivate explicit DAD (Duplicate Address Detection) on int0 interface
+      since this is the default behavior of systemd v250.5 (Yocto release kirkstone) 
+      for static IPv4 addresses if the IP address is a link local address.
+    - Correct outdated mender command in prints of usrp_update_fs utility
+    - No longer import from from rpc_server when already importing usrp_mpm
+  - X400 Platform
+    - Add PPS interface to X410/X440 BSP
+    - Add netlist make flow
+    - Update PS DRAM speed bin
+    - Replace Ethernet transport adapter
+  - X410
+    - Set Locale for ZBX Lattice build
+    - Improve Lattice make flow
+  - X440
+    - Fix error in master clock table for 1000MHz mcr.
+    - Place SPI into IOB on X440
+    - mpm
+      - Add error for recurring TA node inst values
+      - Fix warning about different converter rates
+      - Fix MTS skip for dual-rate
+      - Use greatest converter rate for sysref rate
+      - Add warning for bad conv rate order
+      - Enable multiple LMK VCO rates per MCR
+  - Examples
+    - Fix rx_samples_to_file failure for multichannel fullpath.
+    - Fixed bugs observing cmd argument -c in remote_rx.py example.
+    - Updated tx_waveforms examples now also use timed commands during frequency tuning.
+      On X440 this allows reproducing specified channel to channel phase alignments. 
+* Validated OS Environments
+  (Versions for build and runtime dependencies can be determined from the
+   docker container definitions in the UHD repository at .ci/docker/...)
+  - Linux 
+    - Ubuntu: bionic (18.04), focal (20.04), jammy (22.04), noble (24.04)
+    - Fedora: 34, 35, 36 
+  - Windows: 10 21H2, 11 21H2
+  - MacOS: Monterey (12.6)
