v1.9.2

Hotfix for v1.9.1. Updated logic of rate limiter to better handle batch requests. It was "stress tested" for 3 hours in a row and had no issues.

v1.9.1

Hotfix for v1.9.0. I've got reports from (2) larger bot developers that at scale - they got temporarily blocked by Discord's CloudFlare anti DDoS after sending ~15k requests in less than 10min. This appear to be a bug with handling retryable (mostly 429 error) requests. At large scale, bot may have dozens of ticking retryable requests and previously they were incorrectly handled (partially outside rate limit checks). This hotfix introduces:

• Fixes to original issue by adding missing checks and adding extra time sleep (for network backoff).
• Adds internal retryable requester counter - it will fail early & send error if REST Client detects suspicious amount of failed but retryable requests (there's a chance they happen due to Tempest bug but they also may be because of bad code or network issues).

v1.9.0

[!NOTE] This release would normally be versioned as v1.8.1, but it was promoted to v1.9.0 due to the possibility that the new API rate limiter could introduce breaking changes to some API calls.

What's Changed

• Upgraded REST implementation so now it also handles regional (per /endpoint) rate limit buckets. It uses by default quite aggressive settings for performance reasons but everything is configurable. Rate limiter can be disabled by providing custom http transport into http client used by REST Client. By default it may look like Tempest again consumes more memory - don't panic! It only sweeps old bucket data at specific thresholds to avoid spam of sweeping events. Example of it working:

• Improved documentation of various components, structs and examples by @​Bertie690 in amatsagu/tempest#62
• Added formatting/linting pre-commit hooks with Lefthook & golangci-lint by @​Bertie690 in amatsagu/tempest#65
• Fixed grammar typos in README + moved info about how to contribute into dedicated CONTRIBUTING.md by @​Bertie690 in amatsagu/tempest#64

v1.8.0

What's Changed

• Added optional support for zlib-stream compression for GatewayClient (works only for incoming payloads over ws conn to gateway). It can reduce size of incoming requests by up to ~70% at cost of slightly higher CPU usage.
• Fixed potential race condition in Shard/Socket logic where (at least in theory) Shard logic could crash when trying to close and read/write from different goroutines in nearly the same time (max ~4ns time window).
• Added missing status fields from presence update event payload. It now allows Tempest powered Discord Applicattions to display custom status.
