Release notes:

0.6.0 - 2025-08-15

Highlights

• This release bumps the minimum h2 crate dependency to guard against the [MadeYouReset]((https://blog.cloudflare.com/madeyoureset-an-http-2-vulnerability-thwarted-by-rapid-reset-mitigations/)) H2 attack

🚀 Features

• Log runtime names during Server shutdown
• Enabling tracking the execution phase of a server
• Allow using in-memory compression dicts
• Make H2Options configurable at HttpServer, HttpProxy

Also adds HttpServerOptions to the HttpServer implementation, and updates the HttpEchoApp to use HttpServer for easier adhoc testing.

🐛 Bug Fixes

• Fix: read body without discard

Everything Else

• Try loading each LRU shard individually and warn on errors
• Update LRU save to disk to be atomic
• Allow cache to spawn_async_purge
• Pass hit handler in hit filter
• Cache hit filter can mutate cache, allow resetting cache lock
• Persist keepalive_timeout between requests on same stream
• Properly check for H2 io ReadError retry types
• Add cache lock wait timeout for readers
• Fix CacheLock status timeout conditions
• Handle close on partial chunk head
• Allow optional to reset session timeouts
• Clippy fixes for 1.87, add 1.87 to GitHub CI
• Run range_{header,body}_filter after disabling cache
• Convert InterpretCacheControl members to Duration
• Disable downstream ranging on max file size
• Allow explicit infinite keepalive timeout to be respected

Note that a necessary follow up is to refactor the infinite keepalive timeout to only apply to first read between requests on reused conns.

• Add method to disable keepalive if downstream is unfinished
• Discard extra upstream body and disable keepalive
• Explicitly disable keepalive on upstream connection when excess body

(content-length) is detected.

• Add brief sleep to shutdown signal tests to avoid flake
• Allow override of cache lock timeouts
• Allow arbitrary bytes in CacheKey instead of just Strings
• Corrects out-of-order data return after multiple peek calls with different buffer sizes.
• Mark previously too large chunked assets as cacheable
• Boring/OpenSSL load cert chain from connector options
• Add initial support for multipart range requests
• Adds a callback to HttpHealthCheck for collecting detailed backend summary information
• Multipart range filter state fixes
