6. Push your changes and check
[travis-ci.org](https://travis-ci.org/) for your build results.
## Caches
Travis keeps the caches separate for different jobs. As soon as the job
description (in the `.travis.yml` configuration file) or its environment
settings change (adding a space character is enough), the cache is different
and will be rebuilt when the job runs.
This also means that changing a value inside a setup file will _not_
invalidate the cache - in that case you will have to manually delete the cache
through the Travis web interface. (Or add a space character in the job
configuration.)
Caches are automatically removed after approx. four weeks.
Your jobs will have to rebuild them once in a while.
