v1.1.1
What's Changed
Bugfixes
- frame buffer was accidentally changing encoding before header packing, which raise invalid compatible encoding errors, due to usage of "String#". this was fixed by using internal
append_str´, which does not touch encoding, and callingString.force_encoding` in case the buffer is a mutable string passed by the user. - dup PING frame payload passed by the user; while not really resulting in invalid encoding, the change of the input string could surprise the caller, since this would be expected to be stored somewhere so the peer PING frame can be matched on receive.
Improvements
Simplified String#transition, making sure it only does state machine transitions (the rest is handled outside of it).

v1.1.0
What's Changed
- Several changes which improved performance for the common cases. A few highlights:
- Opting into ruby 3.4 features when possible (such as
String#append_as_bytesinstead ofString#<<) - reducing string and array allocations on several places (connection management, frame generation, hpack header compression, etc)
- "streams recently closed" not having to regenerate the list when not necessary
- Opting into ruby 3.4 features when possible (such as
- adding release workflow for github actions to enable trusted publishing

v1.0.2
What's Changed
Improvements
- Freezing static tables (used for header huffman coding) correctly. This makes them shareable, which makes
http-2usable across ractors. - Moved buffer helpers from String refinements into mixins. Refinements impose a relevant performance penalty, unfortunately, despite its cleaner API.

Bugfixes
- allow RST_STREAM frames to be ignored on closed streams.
- prevent already closed streams from being initialized again.

v1.0.0
Breaking changes
- Set ruby 2.7 as the lowest supported ruby version.
There are no public API breaking changes.
Improvements
- it passes the h2spec compliance suite.
- RBS signatures.
- Using the :buffer kwarg from Array#pack to reduce string allocations
- Using #drop_while enumerable function to drop timed out recently closed streams, which reduced the complexity of it from O(n) to O(log n), making a difference in a few benchmarks.
- optimization for header decompression of static headers.
- it was identified that traversing the static headers table for each incoming header was one of the bottlenecks, and it was O(n) for all cases where there was not an exact match. In order to circumvent this, an additional table derived from the static headers table with the header field as lookup key was created, which eliminated the main bottleneck (at the cost of roughly 1.5Kb extra).
- HTTPX::Buffer has been removed, and was replaced by String usage with an enhanced API via refinements.
- Using String#byteslice in significant chunks of the parsing process.
- Removed usage of Time.now and replaced it with monotonic time calculations.
- avoid needless header downcase calls.
- using class_eval instead of define_method for performant lookups.
- support for the ORIGIN frame.
Bugfixes
- force-encode data payloads to ascii while creating DATA frames.
- fixed "string too short" error when reading headers with no value.
- fixed HTTP/2 trailers (particularly the case where an end-headers flag is sent before the data, and another after data, which also closes the stream, which is valid spec-wise).
- fixed comparison on callbacks when the returned value overwrite eql?.
- bugfix: fixed bookkeeping of recently-closed streams.
- bugfix: wrong window update accounting check causing random flow control errors.
- bugfix: allow stream to send empty end-stream DATA frame even if remote window is exhausted.
- fix: the connection window was being updated when receiving WINDOW_UPDATEs for a stream.
- bugfix: do not update connection remote window on SETTINGS frame (aka the Cloudfront issue).
- do not close stream when receiving frames from streams we've refused locally
Chore
- Removing base64 library usage for ruby 3.3 or higher (as it's going to be removed from bundled gems).
