Note: because of core stable10 "drop PHP 5.6" all apps have had min-version bumped to 10.2
That includes here https://github.com/owncloud/search_elastic/pull/79/files#diff-224bb875c5d3cfcd7621135069013242

If this release needs to be installable on ownCloud core 10.0 and/or 10.1 then min-version will need to be temporarily adjusted, and:

• see if any "require" dependencies in composer.json would be different if PHP platform is backed up to 5.6 (if so, then put 5.6 back and regenerate composer.lock)
• test against actual core 10.1 and/or 10.0.10 releases (not just against current core stable10)

@phil-davis The customer for this consulting Release has the latest Oracle Linux with php72 and wants to install it on 10.0.10

[phil-davis]

Then it is not going to "explode" because the target installation will be running PHP 7.2
But it will need core min-version set back to 10.0 so that the app will let itself be enabled.

@PVince81 hear is the first example of this need to release apps "backwards" to 10.* - "standard" process needs to be sorted out?
