Currently 1.27 is compatible with 5.5-7.0. Security support for those will end on 31 Dec 2018 (5.6). 1.27 is supported until June 2019. It would be good to have 1.27 support 7.1 so there's an actual supported PHP version that can be used with it.
Main things needing backporting would be (I think):
| Subject | Repo | Branch | Lines +/- | |
|---|---|---|---|---|
| RELEASE-NOTES for PHP 7.1 backports | mediawiki/core | REL1_27 | +1 -0 |
| Status | Subtype | Assigned | Task | ||
|---|---|---|---|---|---|
| Resolved | Legoktm | T174262 Make MediaWiki 1.27 (LTS) compatible with PHP 7.1 | |||
| Resolved | Legoktm | T180403 PHP Error "non-numeric value encountered" in CoreParserFunctions if padleft/padright have invalid length values |

Probably worth a sanity check for any PHP 7 fixes/tasks that didn't make it into REL1_27 already

[mediawiki/core@REL1_27] RELEASE-NOTES for PHP 7.1 backports
Closing, because all 7.1 compat fixes in master were backported. If there are any other 7.1 incompatibilities, they can be tracked separately,
