It has been 1.5 years since the last major update on the ISO C++ standardization
progress here. It is not that I got lazy 
, but there was really not much
to share.
This time, things were different. We achieved a nearly unprecedented success — one probably not even expected by most, definitely not by me! 🎉

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.
We made significant progress in the standardization of this library during the ISO C++ Committee meeting in St. Louis.
The Tokyo 2024 meeting was a very important step in the standardization of this library. Several WG21 groups reviewed proposals, and the feedback was really good.
Several groups in the ISO C++ Committee reviewed the P1935: A C++ Approach to Physical Units 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. This resulted in version 2 of the mp-units library that resolved many issues the users and Committee members raised. 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.
