 * Require Octave 7.x or later.
+* Fix Octave 7.x and 8.x compatibility in installation and package loading.
+* Fix `string.missing()` and to actually return a missing value, instead of "".
 * Remove `(fill,rm,standardize)missing` functions, deferring to the Statistics package.
+* Fix `table` "preallocation" constructor to use 0s and ""s for fill values, unless missings are requested using an alternate pseudotype. (For compatibility with Matlab.)
 * Fix `x(ix) = []` element deletion for string, datetime, table, and other classes.
+* Add idempotent one-arg constructor forms for string, datetime, categorical. (But not table.)
 * Add `istable` function.
+* Add `NaS` and `NaC` functions.
 * Rename `+tablicious` package to `+tblish`; merge `+octave` package into `+tblish`.
 * Move `+table_examples` package to `+tblish/+examples`.
+* Make internal-use properties on the main classes Access = private, now that the code is a little more mature.
+* Fix the doco generation, including publishing to GitHub Pages.
