Here we describe the status of LLVM, including major improvements 19from the previous release, improvements in various subprojects of LLVM, and 20some of the current users of the code. All LLVM releases may be downloaded 21from the `LLVM releases web site <https://llvm.org/releases/>`_. 22 23For more information about LLVM, including information about the latest 24release, please check out the `main LLVM web site <https://llvm.org/>`_. If you 25have questions or comments, the `LLVM Developer's Mailing List 26<https://lists.llvm.org/mailman/listinfo/llvm-dev>`_ is a good place to send 27them. 28 29Note that if you are reading this file from a Git checkout or the main 30LLVM web page, this document applies to the *next* release, not the current 31one.

NOTE 37 For small 1-3 sentence descriptions, just add an entry at the end of 38 this list. If your description won't fit comfortably in one bullet 39 point (e.g. maybe you would like to give an example of the 40 functionality, or simply have a lot to talk about), see the `NOTE` below 41 for adding a new subsection. 42 43 44..
