README.md line 19 at r1 (raw file):

Intel no longer accepts patches to this project.
If you have an ongoing need to use this project, are interested in independently developing it, or would like to maintain patches for the open source software community, please create your own fork of this project.
You will find more information [here](https://pmem.io/blog/2022/11/update-on-pmdk-and-our-long-term-support-strategy/).

Can we apply this kind of formatting: https://github.com/pmem/libpmemobj-cpp?
Without it, the announcement is almost invisible.
