At the time I have to use to versions for hardcoding subtitles from avi into mp4.
ffmpeg_v3 (version 302) and ffmpeg_vN (version N-38632-g4cda8aa)
ffmpeg_v3 -i input.avi -c:v libx264 -acodec libfaac -ar 48000 -b:a 160k -vf subtitles=input.ass output.mp4
Unknown encoder 'libfaac'
ffmpeg_vN -i input.avi -c:v libx264 -acodec libfaac -vf subtitles=input.ass -ar 48000 -b:a 160k output.mp4
No such filter: 'subtitles' / Error opening filters!
Is there a version which will do me both at once?

Provide more details, stop using outdated builds with outdated syntax. There is different aac encoder than libfaac available (higher quality) and there is special ass filter.
work either way. No need to explain or expand them.
You may google for.
You also are not telling me what I am supposed to use.
For the purpose of my question:
Due to GPL license reasons ffmpeg versions 2014 onwards do not
contain libfaac anymore.
I try to figure out whether there is version prior to that
which may have that as well as the subtitles filter.
I use batchfiles with my own command lines, working
on hundreds of files a month.
I may spare some time doing recoding and subtitling in one go.
If not I don't bother.

Is this supposed to be a 'No' to my question or what?
Well, at first you are the one that search for help not me - it should be clear from very beginning, second you should provide full information about problem not information that you believe is sufficient to solve the problem (as you can't solve problem by yourself there is a high chance that you are unable to select useful information).
Read how to provide full information about ffmpeg usage problem - don't like my links - google this by your self.
If you didn't change anything and suddenly something not working as before then i think problem is not in ffmpeg but in data - perhaps extension not matching file type?
libfaac is low quality aac encoder and ffmpeg improved own aac encoder so much that libfaac is no longer counted as usable aac encoder - unless you pursuing special functionality unique for libfaac then there is no sense to stuck with it - if you need libfaac then consider to compile own ffmpeg - wise people already advised you this path.
