 ## Changes (including requirement changes)
 
+* 20240424-0: Made the following changes:
+  * [Add libairspyhf latest version document.](https://github.com/jj1bdx/airspy-fmradion/pull/80)
+    * Airspy HF+ Firmware R3.0.7 and R4.0.8 both work OK on libairspyhf 1.6.8.
+    * For the Firmware R4.0.8, use libairspy 1.8 to have full compatibility.
+  * [Use shared libraries for airspy, airspyhf, and rtl-sdr.](https://github.com/jj1bdx/airspy-fmradion/pull/79)
+  * Tested `airspy_set_packing()` for Airspy R2, but this increased CPU usage on Apple Silicon M2 Pro, so the change was not incorporated.
 * 20240316-0: Made the following changes:
   * Raspberry Pi 4 with Raspberry Pi OS 64bit lite is now officially tested.
   * *Note well: Raspberry Pi OS 32bit is not supported*.

+# libairspyhf and Airspy HF+ firmware versions
+
+## Airspy HF+ firmware version details
+
+* See [Airspy HF+ Firmware changelog](https://airspy.com/downloads/hfplus_changelog.txt) for the details.
+
+## libairspy version compatibility with Airspy HF+ firmware versions
+
+* R3.0.7 and R4.0.8 both work OK on libairspyhf 1.6.8.
+* For R4.0.8, use libairspy 1.8 to have full compatibility.
+
+## For macOS Homebrew
+
+To install the latest libairspyhf:
+
+```sh
+brew install airspyhf --HEAD
+
+```
+
+## pkgconfig precedence
+
+You may need to add precedence of `/usr/local/lib/pkg-config` for `PKG_CONFIG_PATH` when building airspy-fmradion, as:
+
+```
+export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH}"
+```
+
+## libairspyhf 1.8 udev rules for Linux
+
+You have to modify `/etc/udev/rules.d/52-airspyhf.rules` as:
+
+```
+ATTR{idVendor}=="03eb", ATTR{idProduct}=="800c", SYMLINK+="airspyhf-%k", TAG+="uaccess", MODE="660", GROUP="plugdev"
+```
+
+Otherwise Airspy HF+ device will not be recognized when plugged in.
+
+See [GitHub issue airspy/airspyhf#46](https://github.com/airspy/airspyhf/issues/46) for the details.
