LCJones and Brian Wolff: Thanks for taking the time to write a reply.

The comments were useful. I am still trying to navigate through the extensions update. I do want to stick with git.

Updating the extensions seems simple enough:

$ cd ParserFunctions/ $ git pull $ git checkout origin/REL1_27 HEAD is now at d0a5d10... Creating new REL1_27 branch

What has me confused is that on "https://.../thewiki/Special:Version" still shows the old 'ParserFunctions' version.

I then tried... --- thewiki/extensions$ mv OLD__ParserFunctions/ ParserFunctions/ thewiki/extensions$ git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/ParserFunctions.git thewiki/extensions$ ParserFunctions# git checkout origin/REL1_27 --- The last command -- gives me a result that reads HEAD is now at d0a5d10... Creating new REL1_27 branch

Interesting is that "Special:Version" still shows the old 'ParserFunctions' version. I'm still missing something.

I am fairly sure git pulled the newer extensions and I checked-out the right version... but an update is somehow missing.

It looks like MediaWiki isn't finding the new extensions -- I'm trying to go to 1.27.

https://www.mediawiki.org/wiki/Composer - talks of updating vendor.git. I did do that -- --- cd ...thewiki/vendor # git pull # git checkout origin/REL1_27 HEAD is now at f049e1a... Bump wikimedia/ip-set to 1.1.0 ---

Is it is related to 'composer.local.json' - which is discussed in connection with 'Composer'? I did try creating a "composer.local.json" from the sample. https://www.mediawiki.org/wiki/Composer ??? I haven't wrapped my head about this. Any thoughts?

Thanks, Michael
