 Changes to TableGen
 -------------------
 
-* Added constructs for debugging TableGen files:
-
-  * `dump` keyword to dump messages to standard error, see
-     https://github.com/llvm/llvm-project/pull/68793.
-  * `!repr` bang operator to inspect the content of values, see

 Changes to Interprocedural Optimizations
 ----------------------------------------
 
 Changes to the AArch64 Backend
 ------------------------------
 
-* Added support for Cortex-A520, Cortex-A720 and Cortex-X4 CPUs.
-
-* Neoverse-N2 was incorrectly marked as an Armv8.5a core. This has been
-  changed to an Armv9.0a core. However, crypto options are not enabled
-  by default for Armv9 cores, so `-mcpu=neoverse-n2+crypto` is now required
-  to enable crypto for this core. As far as the compiler is concerned,
-  Armv9.0a has the same features enabled as Armv8.5a, with the exception
-  of crypto.
-
 Changes to the AMDGPU Backend
 -----------------------------
 
-* `llvm.sqrt.f32` is now lowered correctly. Use `llvm.amdgcn.sqrt.f32`
-  for raw instruction access.
-
-* Implemented `llvm.stacksave` and `llvm.stackrestore` intrinsics.
-
-* Implemented :ref:`llvm.get.rounding <int_get_rounding>`

 Changes to the RISC-V Backend
 -----------------------------
 
-* The Zfa extension version was upgraded to 1.0 and is no longer experimental.
-* Zihintntl extension version was upgraded to 1.0 and is no longer experimental.
-* Intrinsics were added for Zk*, Zbb, and Zbc. See https://github.com/riscv-non-isa/riscv-c-api-doc/blob/master/riscv-c-api.md#scalar-bit-manipulation-extension-intrinsics
-* Default ABI with F but without D was changed to ilp32f for RV32 and to lp64f for RV64.
-* The Zvbb, Zvbc, Zvkb, Zvkg, Zvkn, Zvknc, Zvkned, Zvkng, Zvknha, Zvknhb, Zvks,
-  Zvksc, Zvksed, Zvksg, Zvksh, and Zvkt extension version was upgraded to 1.0
-  and is no longer experimental.  However, the C intrinsics for these extensions
-  are still experimental.  To use the C intrinsics for these extensions,
-  ``-menable-experimental-extensions`` needs to be passed to Clang.
-* XSfcie extension and SiFive CSRs and instructions that were associated with
-  it have been removed. None of these CSRs and instructions were part of
-  "SiFive Custom Instruction Extension" as SiFive defines it. The LLVM project
-  needs to work with SiFive to define and document real extension names for
-  individual CSRs and instructions.
-* ``-mcpu=sifive-p450`` was added.
-* CodeGen of RV32E/RV64E was supported experimentally.
-* CodeGen of ilp32e/lp64e was supported experimentally.
-* Support was added for the Ziccif, Ziccrse, Ziccamoa, Zicclsm, Za64rs, Za128rs
-  and Zic64b extensions which were introduced as a part of the RISC-V Profiles
-  specification.
-* The Smepmp 1.0 extension is now supported.
-* ``-mcpu=sifive-p670`` was added.
-
 Changes to the WebAssembly Backend
 ----------------------------------
 
 Changes to the Windows Target
 -----------------------------
 
-* The LLVM filesystem class ``UniqueID`` and function ``equivalent()``
-  no longer determine that distinct different path names for the same
-  hard linked file actually are equal. This is an intentional tradeoff in a
-  bug fix, where the bug used to cause distinct files to be considered
-  equivalent on some file systems. This change fixed the issues
-  https://github.com/llvm/llvm-project/issues/61401 and
-  https://github.com/llvm/llvm-project/issues/22079.
-
 Changes to the X86 Backend
 --------------------------
 
-* The ``i128`` type now matches GCC and clang's ``__int128`` type. This mainly
-  benefits external projects such as Rust which aim to be binary compatible
-  with C, but also fixes code generation where LLVM already assumed that the
-  type matched and called into libgcc helper functions.
-* Support ISA of ``USER_MSR``.
-* Support ISA of ``AVX10.1-256`` and ``AVX10.1-512``.
-* ``-mcpu=pantherlake`` and ``-mcpu=clearwaterforest`` are now supported.
-* ``-mapxf`` is supported.
-* Marking global variables with ``code_model = "small"/"large"`` in the IR now
-  overrides the global code model to allow 32-bit relocations or require 64-bit
-  relocations to the global variable.
-* The medium code model's code generation was audited to be more similar to the
-  small code model where possible.
-
 Changes to the OCaml bindings
 -----------------------------
 
 Changes to the Python bindings
 ------------------------------
 
-* The python bindings have been removed.
-
-
 Changes to the C API
 --------------------
 
-* Added ``LLVMGetTailCallKind`` and ``LLVMSetTailCallKind`` to
-  allow getting and setting ``tail``, ``musttail``, and ``notail``
-  attributes on call instructions.
-* The following functions for creating constant expressions have been removed,
-  because the underlying constant expressions are no longer supported. Instead,
-  an instruction should be created using the ``LLVMBuildXYZ`` APIs, which will
-  constant fold the operands if possible and create an instruction otherwise:
-
-  * ``LLVMConstAnd``
-  * ``LLVMConstOr``
-  * ``LLVMConstLShr``
-  * ``LLVMConstAShr``
-  * ``LLVMConstZExt``
-  * ``LLVMConstSExt``
-  * ``LLVMConstZExtOrBitCast``
-  * ``LLVMConstSExtOrBitCast``
-  * ``LLVMConstIntCast``
-  * ``LLVMConstFPTrunc``
-  * ``LLVMConstFPExt``
-  * ``LLVMConstFPToUI``
-  * ``LLVMConstFPToSI``
-  * ``LLVMConstUIToFP``
-  * ``LLVMConstSIToFP``
-  * ``LLVMConstFPCast``
-
-* Added ``LLVMCreateTargetMachineWithOptions``, along with helper functions for
-  an opaque option structure, as an alternative to ``LLVMCreateTargetMachine``.
-  The option structure exposes an additional setting (i.e., the target ABI) and
-  provides default values for unspecified settings.
-
-* Added ``LLVMGetNNeg`` and ``LLVMSetNNeg`` for getting/setting the new nneg flag
-  on zext instructions, and ``LLVMGetIsDisjoint`` and ``LLVMSetIsDisjoint``
-  for getting/setting the new disjoint flag on or instructions.
-
-* Added the following functions for manipulating operand bundles, as well as
-  building ``call`` and ``invoke`` instructions that use operand bundles:
-
-  * ``LLVMBuildCallWithOperandBundles``
-  * ``LLVMBuildInvokeWithOperandBundles``
-  * ``LLVMCreateOperandBundle``
-  * ``LLVMDisposeOperandBundle``
-  * ``LLVMGetNumOperandBundles``
-  * ``LLVMGetOperandBundleAtIndex``
-  * ``LLVMGetNumOperandBundleArgs``
-  * ``LLVMGetOperandBundleArgAtIndex``
-  * ``LLVMGetOperandBundleTag``
-
-* Added ``LLVMGetFastMathFlags`` and ``LLVMSetFastMathFlags`` for getting/setting
-  the fast-math flags of an instruction, as well as ``LLVMCanValueUseFastMathFlags``
-  for checking if an instruction can use such flags
-
 Changes to the CodeGen infrastructure
 -------------------------------------
 
-* A new debug type ``isel-dump`` is added to show only the SelectionDAG dumps
-  after each ISel phase (i.e. ``-debug-only=isel-dump``). This new debug type
-  can be filtered by function names using ``-filter-print-funcs=<function names>``,
-  the same flag used to filter IR dumps after each Pass. Note that the existing
-  ``-debug-only=isel`` will take precedence over the new behavior and
-  print SelectionDAG dumps of every single function regardless of
-  ``-filter-print-funcs``'s values.
-
-* ``PrologEpilogInserter`` no longer supports register scavenging
-  during forwards frame index elimination. Targets should use
-  backwards frame index elimination instead.
-
-* ``RegScavenger`` no longer supports forwards register
-  scavenging. Clients should use backwards register scavenging
-  instead, which is preferred because it does not depend on accurate
-  kill flags.
-
 Changes to the Metadata Info
 ---------------------------------
-* Added a new loop metadata `!{!"llvm.loop.align", i32 64}`
 
 Changes to the Debug Info
 ---------------------------------
 
 Changes to the LLVM tools
 ---------------------------------
 
-* llvm-symbolizer now treats invalid input as an address for which source
-  information is not found.
-* llvm-readelf now supports ``--extra-sym-info`` (``-X``) to display extra
-  information (section name) when showing symbols.
-
-* ``llvm-nm`` now supports the ``--line-numbers`` (``-l``) option to use
-  debugging information to print symbols' filenames and line numbers.
-
-* llvm-symbolizer and llvm-addr2line now support addresses specified as symbol names.
-
-* llvm-objcopy now supports ``--gap-fill`` and ``--pad-to`` options, for
-  ELF input and binary output files only.
-
 Changes to LLDB
 ---------------------------------
 
-* ``SBWatchpoint::GetHardwareIndex`` is deprecated and now returns -1
-  to indicate the index is unavailable.
-* Methods in SBHostOS related to threads have had their implementations
-  removed. These methods will return a value indicating failure.
-* ``SBType::FindDirectNestedType`` function is added. It's useful
-  for formatters to quickly find directly nested type when it's known
-  where to search for it, avoiding more expensive global search via
-  ``SBTarget::FindFirstType``.
-* ``lldb-vscode`` was renamed to ``lldb-dap`` and and its installation
-  instructions have been updated to reflect this. The underlying functionality
-  remains unchanged.
-* The ``mte_ctrl`` register can now be read from AArch64 Linux core files.
-* LLDB on AArch64 Linux now supports debugging the Scalable Matrix Extension
-  (SME) and Scalable Matrix Extension 2 (SME2) for both live processes and core
-  files. For details refer to the
-  `AArch64 Linux documentation <https://lldb.llvm.org/use/aarch64-linux.html>`_.
-* LLDB now supports symbol and binary acquisition automatically using the
-  DEBUFINFOD protocol. The standard mechanism of specifying DEBUFINOD servers in
-  the ``DEBUGINFOD_URLS`` environment variable is used by default. In addition,
-  users can specify servers to request symbols from using the LLDB setting
-  ``plugin.symbol-locator.debuginfod.server_urls``, override or adding to the
-  environment variable.
-
-
-* When running on AArch64 Linux, ``lldb-server`` now provides register
-  field information for the following registers: ``cpsr``, ``fpcr``,
-  ``fpsr``, ``svcr`` and ``mte_ctrl``. ::
-
-    (lldb) register read cpsr
-          cpsr = 0x80001000
-               = (N = 1, Z = 0, C = 0, V = 0, SS = 0, IL = 0, <...>
-
-  This is only available when ``lldb`` is built with XML support.
-  Where possible the CPU's capabilities are used to decide which
-  fields are present, however this is not always possible or entirely
-  accurate. If in doubt, refer to the numerical value.
-
 Changes to Sanitizers
 ---------------------
-* HWASan now defaults to detecting use-after-scope bugs.
 
 Other Changes
 -------------
 
-* The ``Flags`` field of ``llvm::opt::Option`` has been split into ``Flags``
-  and ``Visibility`` to simplify option sharing between various drivers (such
-  as ``clang``, ``clang-cl``, or ``flang``) that rely on Clang's Options.td.
-  Overloads of ``llvm::opt::OptTable`` that use ``FlagsToInclude`` have been
-  deprecated. There is a script and instructions on how to resolve conflicts -
-  see https://reviews.llvm.org/D157150 and https://reviews.llvm.org/D157151 for
-  details.
-
-* On Linux, FreeBSD, and NetBSD, setting the environment variable
-  ``LLVM_ENABLE_SYMBOLIZER_MARKUP`` causes tools to print stacktraces using
-  :doc:`Symbolizer Markup <SymbolizerMarkupFormat>`.
-  This works even if the tools have no embedded symbol information (i.e. are
-  fully stripped); :doc:`llvm-symbolizer <CommandGuide/llvm-symbolizer>` can
-  symbolize the markup afterwards using ``debuginfod``.
