The PRs pandas-dev#55792 (Y), pandas-dev#52064 (Q), and pandas-dev#55553 (M) deprecated the single letter version of the aliases in favour of the -end version of them. This table was missed as part of that work.
The PRs pandas-dev#55792 (Y), pandas-dev#52064 (Q), and pandas-dev#55553 (M) deprecated the single letter version of the aliases in favour of the -end version of them. Add a note to the offset table about deprecations.
xref #9586, #52064
Deprecated the alias denoting year end frequency “Y” for offsets in favour of “YE".
