+## Agenda
+
+- [Open action items](https://hackmd.io/ovrbJj6CRduRgSA0Wzg2zg)
+- [Try trait v2](https://github.com/scottmcm/rfcs/blob/do-or-do-not/text/0000-try-trait-v2.md#summary)
+- ~~Edition range changes~~
+- ~~Triage~~
+- ~~Anything else?~~
+
+## Try trait
+
+- Consider a `FromTryOutput` trait for types you can inspect and break on, but can't construct (such as errors from FFI). That would split `from_output` off of `Try`.
+    - Path forward: follow exactly what the RFC follows and see whether people run into `from_output`.
+- On naming: is it possible to reduce the number of distinct nouns we introduce? Do _Continue_ and _Break_ work?
+    - Path forward: follow the _Residual_ naming and see if better names come forward in the meantime.
+
+- Look at crater breakage from `Option` to `Result` breakage.
+
+Two crater runs:
+
+- One with the RFC as-written including the workaround for `Option` to `Result`.
+- One without the workaround for `Option` to `Result`.
+
+## Triage
