C23 (C standard revision)

[3] The freely available draft most similar to the one published is document N3220[4] (see Available texts, below).

The common names "C17" and "C23" reflect these values, which are frozen prior to final adoption, rather than the years in the ISO standards identifiers (9899:2018 and 9899:2024).

[6] Some old obsolete features are either removed or deprecated from the working draft of C23: The following compilers implement an experimental compiler flag to support this standard: Like other editions of the C standard, the official ISO text of the standard is not freely available.

The latest working draft pre-C23 that was made public was N3096,[6] dated 2023-04-01.

While this document is officially described[72] as a draft of the future version "C2Y" of the standard, the accompanying "Editor's Report" specifies that N3220 differs from the draft C23 standard N3219 only by a fix to one footnote in Annex K.[72]
