On Help:Magic words#Statistics I can exactly determine when and where NUMBEROFVIEWS was introduced: Special:Code/MediaWiki/42721 blames CoreParserFunctions.php in SVN revision 42721 (2008-10-28). Now I want to figure out if, when, and where this magic word was removed or conditionally disabled here. How can I solve this without a copy of the sources on my box. If NUMBEROFVIEWS turns out to be removed Wikitext_parser/Core_parser_functions#numberofviews also has to be updated.

I recall this commit (now that I found it) but I found it using git bisect.
Thanks, I've updated the help and the parser pages. There's now an interesting green + red version box for NUMBEROFVIEWS, instead of only red as for __END__. How could I find out when CoreParserFunctions.php was modified? And how could I check my wild guess 1.23 as the last version with a NUMBEROFVIEWS?
1.24 is the latest version that will have it. You can tell by the inclusion of the RELEASE-NOTES in the linked change request.
Okay, I found 1.25, fixed s/1.23/1.24/ on the help page, and the colours are apparently okay when something (no idea what) on the translation side happens.
