Approach is good, just some comments to make it cleaner.

Trailing white spaces seems to be only remaining thing left.

| 6. `yearqtr()` and `yearmon()` now gain an optional format specifier [#7694](https://github.com/Rdatatable/data.table/issues/7694). 'numeric' is the default, which preserves the original behavior, but 'character' formats `yearqtr()` as YYYYQ# (e.g. 2025Q2) and `yearmon()` as YYYYM## (e.g. 2025M02, 2025M10). Thanks to @jan-swissre for the report and @LunaticSage218 for the implementation. | ||

also needs your name or github tag for thanking yourself.
For the news phrasing itself, maybe something like?
Verbose outputs from `frolladaptivefun()` and `frollfun()` are now clearer and more user friendly

Closes #7021.
Previously, the frolladaptivefun and rfollfun algo verbose messages were not super user friendly, displaying messages like:
frolladaptivefun: algo 0 not implemented, fall back to 1The wanted adjustment was for it to instead produce:
frolladaptivefun: algo fast not implemented, fall back to exactThere was also:
frollfun: processing fun 0 algo 0 took...and the desired result was instead:
frollfun: processing fun mean algo fast took...We adjusted for the desired functionality by creating an array of strings called rfunNames, using the rfun enum as an index to select the proper display type for the running function and then displaying fast or exact dependent on the value of value (0 for fast, 1 for exact).
Here is an example of the current output (from running tests) with the changed files in this PR:
frolladaptivefun: processing fun MIN algo exact took 0.000sfrolladaptivefun: algo fast not implemented, fall back to exactWe have additionally adjusted the NEWS.md file and the corresponding tests in inst/tests/froll.Rraw.
