This pulse was a productive one for us: we released new versions of Pebble, Concierge, and – probably by the time you read this – Ops and Jubilant. We finished the Relation Interface Design spec and got it approved (it will be required to follow that for new charmlibs interface libraries), we refactored some pytest-jubilant warts and released a 2.0 version (it’s now maintained by Charm Tech), we used AI to port charm integration tests from pytest-operator to Jubilant, and we added some Concierge features and fixes.
Ops
-
Releasing Ops 3.7.0 imminently (as soon as CI/Snap store issues are fixed). This release enables interactive debugging, allows ops[testing] to autoload charmcraft extensions (like 12-factor), and contains several smaller features and fixes.
-
Fixed an issue in ops[testing] where complex Pebble plans could get corrupted (#2380)
-
Fixed an issue in ops[testing] where secret-get and action-get didn’t copy the data, so tests could mutate it later (#2379)
-
Fixed an issue with setting secret expiry where the timezone was not UTC (#2378)
Charming
-
OP083 - Relation Interface Design specification has been approved. We’ll start requiring that for charm libraries that wrap interfaces after the sprint.
-
Refactored pytest-jubilant to create a slimmer, namespaced API, and released a 2.0 version.
-
Releasing Jubilant 1.8.0 imminently (as soon as CI/Snap store issues are fixed). This adds the metadata_source option to bootstrap and fixes minor issues.
