It is not a serious problem, I just had to adjust the maxDate on old projects. But I believe it is a good time to update this default value.
For those who do not know how to solve, just edit all datepicker fields, and inform maxDate, for example:
published_at:
label: Published At
type: datepicker
maxDate: 2025-12-31
span : right
If this has already been resolved in newer versions just update the documentation.

This hasn't been the case since Build 326, almost 5 years ago: https://github.com/octobercms/october/commit/be7b3b3009b9ce9023b109e3476382b4f98b3b8b#diff-f69e3431ff35c5c2681d6889b53b21565772cbd1e7b3987f75c503f8c64d0fe6
