+# Report from the Wrocław 2024 ISO C++ Committee meeting
+
+The Wrocław 2024 meeting was another efficient step in the standardization of this library.
+We've spent the entire day on the joint LEWGI and SG6 discussion and got lots of feedback.
+We've also introduced `std::fixed_string` to LEWG for C++26.
+
+<!-- more -->
+
+## [P3045R4: Quantities and units library](https://wg21.link/p3045r4)
+
+We have presented the following chapters of our proposal to LEWGI and SG6. We reviewed all
+the usage examples, discussed composing symbols for derived dimensions and units, and looked into
+formatting specifications for quantities. We also discussed the minimal scope of the proposal.
+
+We got plenty of feedback on:
+
+- the paper itself,
+- naming of specific entities in the library,
+- usage examples,
+- text output and formatting.
+
+We were also asked to extend the library to provide text output support for quantity points.
+
+You can expect all of those changes to appear in the next release.
+
+
+## [P30942R5: `std::basic_fixed_string`](https://wg21.link/p3094r5)
+
+The paper was well received. However, Barry Revzin submitted
+[P3380](https://wg21.link/p3380) paper in September. This started a discussion about the scope of
+this proposal. Should we:
+
+- limit it to just a non-mutating interface (as proposed) and maybe rename it to
+  `std::string_literal`,
+- add range slicing interface (as we support composition already),
+- add some basic mutation interface through non-const `operator[]`,
+- refactor to fully blown `std::inplace_string` if [P3380](https://wg21.link/p3380) successfully
+ progresses through EWG.
