Details
Trooper v3.0 has been released, adding circuit breaker and enhanced observability features.
- When 3 failures within 60 seconds accumulate, the corresponding provider is automatically skipped, reducing the waste of repeatedly requesting an already-dead provider.
- It prints a per-request log line to the terminal, letting you immediately check which path was used to process the request.
- Each response includes an
X-Trooper-Summaryheader that summarizes in one line what Trooper did.
It additionally runs with no dependencies and remains a single Go binary.
