 ## [Unreleased](https://github.com/gnss-sdr/gnss-sdr/tree/next)
 
+### Improvements in Portability:
+
+- Improved detection of the BLAS library under macOS / Macports (the `lapack`
+  port dependency installed with the `+openblas` variant does not install `blas`
+  but `openblas`, which is used as a replacement if `blas` is not found).
+- Removed duplicated files in the Secure User Plane Location implementation,
+  which caused issues when linking with some compilers.
+- Added support for Xilinx's Zynq UltraScale+ devices (requires the
+  `-DENABLE_FPGA=ON` building option).
+
+### Improvements in Usability:
+
+- Fixed large GLONASS velocity errors when using the
+  `GLONASS_L1_CA_DLL_PLL_C_Aid_Tracking` and
+  `GLONASS_L2_CA_DLL_PLL_C_Aid_Tracking` implementations.

+
 ### Improvements in Availability:
 
 - Compute PVT solutions when using GPS L5 signals even if the satellite is
   reported as not healthy in the CNAV message.
 
+### Improvements in Portability:
+
+- Updated `cpu_features` library to v0.7.0. The building option
+  `ENABLE_OWN_CPUFEATURES` has been replaced by `ENABLE_CPUFEATURES`, defaulting
+  to `ON`.
+- Fixed building against GNU Radio v3.10.2.0.
+
 ### Improvements in Reliability:
 
 - Fix some defects detected by Coverity Scan 2021.12.1.
 
+### Improvements in Usability:
+
+- Added a script at `src/utils/scripts/download-galileo-almanac.sh` that
+  downloads an XML file with the latest Galileo almanac published by the
+  European GNSS Service Centre at https://www.gsc-europa.eu/product-almanacs

+
+DESCRIPTION
+\tCross compile using a cross toolchain.
+
+\tYou MUST define the following variables before running this script:
+\t* TARGET:
+\t\tx86_64
+\t\taarch64-linux-gnu aarch64_be-linux-gnu
+\t\tarm-linux-gnueabihf armv8l-linux-gnueabihf arm-linux-gnueabi
+\t\tarmeb-linux-gnueabihf armeb-linux-gnueabi
+\t\tmips32 mips32el
+\t\tmips64 mips64el
+
+OPTIONS
+\t-h --help: show this help text
+\ttoolchain: download, unpack toolchain and generate CMake toolchain file
+\tbuild: toolchain + build the project using the toolchain file (note: remove previous build dir)
+\tqemu: download, unpack and build qemu
+\ttest: qemu + run all executable using qemu (note: don't build !)
+\tall: build + test (default)
+
+EXAMPLES
+* Using export:
+export TARGET=aarch64-linux-gnu
+$0
+
+* One-liner:
+TARGET=aarch64-linux-gnu $0"
