+    *** Release 11.3.0 ***
+
+    Noteworthy changes compared to the previous release, 11.2.1:
+
+    New features:
+        - Implement "TSC Frequency" feature of the Limine boot protocol.
+        - Add PIT-based TSC calibration for BIOS.
+        - Do not clear framebuffer in quiet mode.
+
+    Bug fixes:
+        - Make "Keep IOMMU" Limine boot protocol feature x86-64-only.
+        - Do not clear framebuffer on modeset as Flanterm immediately repaints
+          it, wasting time.
+        - Allow menu recovery on overflow panics in the multiboot protocols.
+        - Significantly improve TSC calibration accuracy.
+
+    Miscellaneous:
+        - Do not force-start uninitialised GOP outputs if a framebuffer is
+          already available, for compatibility with quirky firmwares (Apple
+          Macs).
+        - Call Apple set_os protocol on UEFI to try to keep iGPU alive on
+          dual-GPU Apple Macs.
+        - Migrated to GitHub alongside with several subprojects.
+        - Build limine.exe using i486 MinGW from osdev0/mingw-binary-builds
+          in binary builds for better compatibility.
