## Changelog
|
||||
|
||||
### v0.1.4
|
||||
|
||||
- **Never-raises net widened:** an unexpected exception that escapes a send attempt (a
|
||||
closed injected session → `RuntimeError`, a malformed proxy URL → `ValueError`) now
|
||||
converts to a falsy `WebhookResult(ok=False, ...)` instead of propagating out of
|
||||
`send()`, restoring the documented contract for those edge triggers.
|
||||
|
||||
### v0.1.3
|
||||
|
||||
- **429 always retries:** every `429` is now retryable under aretry's backoff + cap, not
|
||||
only those with a parseable `retry_after`. A 429 with no body `retry_after` and no
|
||||
`Retry-After` header (edge/Cloudflare/generic webhook) previously failed one-shot.
|
||||
|
||||
### v0.1.2
|
||||
|
||||
- Removed a dead `clock` constructor param (it was stored but never used). Pinned
|
||||
`commons` to v0.2.1.
|
||||
|
||||
### v0.1.1
|
||||
|
||||
- **Never-raises contract hardened:** an error from a duck-typed proxy provider's
|
||||
`get()`/`burn()` (e.g. `aioproxies.burn()` raising `ValueError` for an unknown proxy)
|
||||
used to escape `send()`. Now any provider exception is caught and converted to a
|
||||
failed result.
|
||||
- **Retry via `commons.aretry`:** 429/5xx retry moved onto the shared backoff engine —
|
||||
5xx now backs off (was a tight no-backoff loop), and exhausted retries return the
|
||||
**real** last status/body instead of a synthetic placeholder. Adds a `commons`
|
||||
dependency.
|
||||
|
||||
## Versioning
|
||||
|
||||
Tagged `vX.Y.Z`. Pin the tag.
|
||||
Releases are tagged `vX.Y.Z`. The install line above pins a release; drop the `@vX.Y.Z` suffix to install the latest unpinned. Pin deliberately for reproducible installs.
