+Changes for next bugfix+ release (coming soon):
+
+- CPU and internal debugger
+  - VMX: Implemented TPR shadow VMEXIT
+  - Bugfixes for CPU emulation correctness (mostly for VMX support).
+  - Updates for Bochs internal debugger.
+  - Bugfixes for > 32-bit physical address space.
+
+- Cleanup configure options
+  - All paging related options now will be automatically determined according
+    to  --enable-cpu-level option. Related configure options
+        --enable-global-pages, --enable-large-pages,
+        --enable-pae, --enable-mtrr
+    are deprecated now. Only 1G paging option still remains unchanged.
+  - Deprecate --enable-daz configure option. Denormals-are-zeros MXCSR control
+    will be enabled automatically iff SSE2 is supported (like in hardware).
+  - Deprecate --enable-vme configure option, now it will be supported iff
+    CPU_LEVEL >= 5 (like in hardware).
