Thanks. I wasn’t aware of the caching for platformio installation.
I changed all my projects to update libraries - and after I noted that this does not update the platforms/frameworks, also a line to update these (just
platformio update) - as travis install all libraries globally, this also updates these, so there is no need for an extra
platformio lib -g update.
I think it would be helpful to add the update to the template for project and library of .travis.yml ?
