PHP 7.4 is old (7.4.2)

In the documentation it says

X.Y versions are aliases for recent X.Y.Z releases pre-installed on the build images.

I have in my .travis.yml

dist: bionic
language: php
  - '7.4'

Today this results in PHP 7.4.2 being used. (See my job)

I can see that 7.4.29 is in your system so how about updating the 7.4 image. A PHP bug in that old version is causing my tests to fail.

Did a test run on focal:

7.4.6 (set by /home/travis/.phpenv/version

Thanks for taking a look. 7.4.6 is pretty elderly too. I would have anticipated an automated build would keep them much closer to the latest version.
