Hmm. This isn't a replacement for documentation. IMHO, it *must* be mentioned in the NEWS file (perhaps in the `experimental' section'.
Apart from not having time,
Well, this is a lame excuse: It would have been a matter of 10 seconds, namely to copy Thanh's announcement of the patch verbatim to the NEWS file.
there are many reasons for missing documentation. Perhaps the feature isn't finished and too `experimental'.
Hmm.
Or there are plans to redesign the interfaces. Documentation raises compatibility issues. On the other hand the author will have less feedback without documentation.
Indeed. How shall people try it without knowing this feature at all.
But either way, this decision is up to the author who implements the feature, not the user who wants to use it.
If I interpret the patch correctly, it wasn't Thanh who has applied it -- Thanh has done his job correctly providing the necessary details of how to use his new extension, but the applier missed to update the NEWS file. Werner
