Yes, but in my case tomcat is provided by the distribution and I&#x27;ll see when an update is coming (and to be honest, like you said, tomcat is pretty boring, which is good in my opinion). By default, dokku&#x2F;herokuish will download the latest version of a buildpack, that&#x27;s what got me this time. As other commenters pointed out, I could lock down a specific commit for the buildpack, I&#x27;ll try that in the future.
