Re: New Unicode Versions Update for Pipeline

Normally the annual updates will be a major version update. Unicode 15.1 in 2023 was an unusual exception. Because of process changes that were being made, the initial plan for 2023 was a 15.1 release with limited scope of changes, including a very small number of new characters---see L2/22-270<https://www.unicode.org/L2/L2022/22270-rel-mgmt-recs.pdf> for details. Later, it became necessary to add CJK Extention I to the scope, but the scope was still constrained in general. The changes to UAX #29 were carefully considered in relation to capacity before they were approved for 15.1.

Subject: Re: New Unicode Versions Update for Pipeline
How does the whole version numbering thing work deciding between major and minor in the annual update? The last time there was a minor version update, it included a major change to the logic for grapheme segmentation rather than the usual updates to the data tables.
