   Windows 7. Earlier versions, including Windows Vista and XP are no longer
   supported.
 
+* With this release, the autoconf build system is deprecated. It will be removed
+  in the 3.9 release. Please migrate to using CMake. For more information see:
+  `Building LLVM with CMake <CMake.html>`_
+
+* The C API function LLVMLinkModules is deprecated. It will be removed in the
+  3.9 release. Please migrate to LLVMLinkModules2. Unlike the old function the
+  new one
+
+   * Doesn't take an unused parameter.
+   * Destroys the source instead of only damaging it.
+   * Does not record a message. Use the diagnostic handler instead.
+
+* The C API functions LLVMParseBitcode, LLVMParseBitcodeInContext,
+  LLVMGetBitcodeModuleInContext and LLVMGetBitcodeModule have been deprecated.
+  They will be removed in 3.9. Please migrate to the versions with a 2 suffix.
+  Unlike the old ones the new ones do not record a diagnostic message. Use
+  the diagnostic handler instead.
+
+* The deprecated C APIs LLVMGetBitcodeModuleProviderInContext and
+  LLVMGetBitcodeModuleProvider have been removed.
+
+* The deprecated C APIs LLVMCreateExecutionEngine, LLVMCreateInterpreter,
+  LLVMCreateJITCompiler, LLVMAddModuleProvider and LLVMRemoveModuleProvider
+  have been removed.
+
+* With this release, the C API headers have been reorganized to improve build
+  time. Type specific declarations have been moved to Type.h, and error
+  handling routines have been moved to ErrorHandling.h. Both are included in
+  Core.h so nothing should change for projects directly including the headers,
+  but transitive dependencies may be affected.
+
+* llvm-ar now suports thin archives.
+
+* llvm doesn't produce .data.rel.ro.local or .data.rel sections anymore.
+
+* aliases to available_externally globals are now rejected by the verifier.
+
+* the IR Linker has been split into IRMover that moves bits from one module to
+  another and Linker proper that decides what to link.
+
+* Support for dematerializing has been dropped.
