> (see C++ > MSVC Build Tools 14.51 > Standard Library (STL) > Other notable
> changes) removed support for some old, deprecated and non-standard STL
> extensions, including `hash_map` and `hash_set`. Both of these were used in
> `GlassClipboard`'s Windows part. Because of this change, JavaFX does not
> build under Visual Studio 2026 18.6 and later.
>
> This commit replaces deprecated `hash_map` and `hash_set` with STL-equvalent
> `unordered_map` and `unordered_set`. `GlassClipboard` also used (also
> deprecated) `hash_value` template function to calculate hashes for
> non-standard WinAPI object `_bstr_t` and `FORMATETC` ~~(the latter was
> implicitly generated by the extension)~~. Those were also replaced with
> STL-endorsed `std::hash` specializations. No other changes were necessary.
>
> All tests on Windows 11 pass successfully after this change and manual
> testing showed no regressions.

Lukasz Kostyra has updated the pull request incrementally with one additional
commit since the last revision:
Restore old FORMATETC hash implementation
It was somewhere else in the file and I missed it when rewriting the
file to std::unordered_{map,set}.
