GitHub still labels Imp v0.5.0 Latest. Hex published 0.6.0. I checked the Releases API, the v0.6.0 tag, mix.lock, and hex.pm; I didn’t run Imp.

The tag’s lock keeps mint 1.10.1 next to Finch 0.23.0. mint 1.11.0 leaves an HTTP/1 connection open after a receive timeout, and that Finch release returns it to the pool. Finch PR 397 is still open.
