Unreleased

  • The Docker image is now based on Ubuntu instead of Alpine.

v0.0.90

  • The next.jdbc namespace and PostgresQL driver, introduced in v0.0.89, are no longer part of the standardly distributed bb binary. This is now available behind a feature flag. See feature flag documentation.

v0.0.79

  • babashka.curl#9: Functions in babashka.curl like get, post, etc. now always return a map with :status, :body, and :headers.

v0.0.71

v0.0.44 - 0.0.45

  • #173: Rename *in* to *input* (in the user namespace). The reason for this is that it shadowed clojure.core/*in* when used unqualified.
