+# Report from the Kona 2023 ISO C++ Committee meeting
+
+**Several groups in the ISO C++ Committee reviewed the [P1935: A C++ Approach to Physical Units](https://wg21.link/p1935)
+proposal in Belfast 2019 and Prague 2020. All those groups expressed interest in the potential
+standardization of such a library and encouraged further work. The authors also got valuable
+initial feedback that highly influenced the design of the V2 version of the mp-units library.**
+
+In the following years, we scoped on getting more feedback from the production and design and
+developed version 2 of the **mp-units** library that resolves many issues raised by the users and
+Committee members. The features and interfaces of this version are close to being the best we can
+get with the current version of the C++ language standard.
+
+<!-- more -->
+
+For the last ISO C++ Committee meeting, we provided three new proposals related to the
+standardization of the quantities and units library:
+
+- [P2980: A motivation, scope, and plan for a physical quantities and units library](https://wg21.link/p2980R1),
+- [P2981: Improving our safety with a physical quantities and units library](https://wg21.link/p2981R1),
+- [P2982: `std::quantity` as a numeric type](https://wg21.link/p2982R1).
+
+Those were reviewed and briefly discussed in several groups: Numerics (SG6), Safety & Security
+(SG23), and Library Evolution Working Group (LEWG). Most of the feedback was positive, and
+the Committee is interested in spending more time on such proposals.

+
+    Outcome: Strong consensus in favor
+
+Additionally, some concerns were raised about the large scope of the proposal. We were encouraged
+to come back with more details and design rationale in a unified paper. This is what we are working
+on now for the next Committee meeting that will happen in mid-March 2024 in Tokyo.
