Early adopters of the package will note two changes made shortly before the release of the package to CRAN:
The configuration options .gander_fn and
.gander_args have been transitioned to one option,
.gander_chat. That option takes an ellmer Chat, e.g.
options(.gander_chat = ellmer::chat_claude()). If you’ve
configured an ellmer model using the previous options, you’ll get an
error that automatically translates to the new code you need to
use.
There is no longer a default ellmer model. Early in the
development of gander, if you had an ANTHROPIC_API_KEY set
up, the addin would “just work.” While this was convenient for Claude
users, it means that the package spends money on the users behalf
without any explicit opt-in.
