 ## VC Redist Lockdown
 To reduce the frequency of required reboots when updating VS (and VS Previews), we "lock down" the Visual C++ Redistributable containing the STL's `msvcp140.dll`. (Most of the STL is header-only, so most changes are unaffected.) Approximately twice a year, specific VS Previews will be "unlocked", so the VC Redist will contain updated DLLs. VS 2022 17.8 Preview 3 will be the next unlocked redist, then the next Long-Term Support release will be unlocked (it can be Preview 1 if we need).

 # Expected in VS 2022 17.9 Preview 2
-- Merged C++23 features:
-  * [P1169R4](https://wg21.link/P1169R4) [#4053](https://github.com/microsoft/STL/pull/4053) `static` `operator()`
-    + This updates CTAD (class template argument deduction) for `std::function` and `packaged_task` to work with a C++23 Core Language feature, currently supported for Clang only. When MSVC and IntelliSense implement this Core feature, this will automatically "light up" the STL's CTAD for them too.
-- Merged LWG issue resolutions:
-  * [LWG-3561](https://wg21.link/lwg3561) [#4066](https://github.com/microsoft/STL/pull/4066) Issue with internal counter in `discard_block_engine`
 - Fixed bugs:
-  * Fixed linker errors involving `stl_asan.lib` by disabling ASan annotations in the STL for unsupported platforms (e.g. ARM, ARM64, ARM64EC). [#4058](https://github.com/microsoft/STL/pull/4058)
-  * Fixed `deque` to handle highly unusual fancy pointers. [#4049](https://github.com/microsoft/STL/pull/4049)
-  * Fixed `not_fn()` to return a perfect forwarding call wrapper in C++20 mode as required by [P0356R5](https://wg21.link/P0356R5). [#4057](https://github.com/microsoft/STL/pull/4057)
-  * Fixed `deque::shrink_to_fit()` to avoid requiring the allocator to be default constructible. [#4071](https://github.com/microsoft/STL/pull/4071)
   * Fixed `allocate_shared()` for unbounded arrays to handle fancy pointers. [#4074](https://github.com/microsoft/STL/pull/4074)
-- Improved performance:
-  * Improved debug codegen for `deque` by using unchecked iterators internally. [#4071](https://github.com/microsoft/STL/pull/4071)
-- Enhanced behavior:
-  * Improved `source_location::function_name()`: [#4055](https://github.com/microsoft/STL/pull/4055)
-    + It will return detailed information for Clang 17.
-    + Added an "escape hatch" for all compilers: define `_USE_DETAILED_FUNCTION_NAME_IN_SOURCE_LOCATION` to `0`.
-    + For example, given `template <typename T> void cats()` called with `cats<vector<int>>()`, MSVC's detailed info (implemented in VS 2022 17.6) is `"void __cdecl cats<class std::vector<int,class std::allocator<int> >>(void)"`. Clang 17's detailed info is `"void __cdecl cats(void) [T = std::vector<int>]"`. The escape hatch will return the basic info `"cats"`.
-  * Silenced `/Wall` warning C4868 "compiler may not enforce left-to-right evaluation order in braced initializer list" throughout the STL. [#4067](https://github.com/microsoft/STL/pull/4067)
-    + *Note:* `/Wall` is not intended for regular production use, as it contains a large number of extremely noisy and low-value warnings. In general, the STL does not attempt to be `/Wall` clean.
 - Improved test coverage:
-  * Added an ASan-Daily-CI pipeline. [#3987](https://github.com/microsoft/STL/pull/3987) [#3989](https://github.com/microsoft/STL/pull/3989) [#4029](https://github.com/microsoft/STL/pull/4029) [#4052](https://github.com/microsoft/STL/pull/4052) [#4068](https://github.com/microsoft/STL/pull/4068) [#4069](https://github.com/microsoft/STL/pull/4069) [#4075](https://github.com/microsoft/STL/pull/4075)
-- Code cleanups:
-  * Ported a `<format>` table generator script from C++ to Python. [#3994](https://github.com/microsoft/STL/pull/3994)
-- Updated `_MSVC_STL_UPDATE`. [#4062](https://github.com/microsoft/STL/pull/4062)
