http-2 1.1.0 has been released.

Pure Ruby, framework and transport agnostic, implementation of HTTP/2
protocol and HPACK header compression with support for:

* [Binary framing](HTTP: HTTP/2 - High Performance Browser Networking (O'Reilly)) parsing and
encoding
* [Stream multiplexing](HTTP: HTTP/2 - High Performance Browser Networking (O'Reilly))
and [prioritization](HTTP: HTTP/2 - High Performance Browser Networking (O'Reilly))
* Connection and stream [flow control](HTTP: HTTP/2 - High Performance Browser Networking (O'Reilly))
* [Header compression](HTTP: HTTP/2 - High Performance Browser Networking (O'Reilly)) and
[server push](HTTP: HTTP/2 - High Performance Browser Networking (O'Reilly))
* Connection and stream management
* And more... see [API docs](File: README — Documentation for http-2 (1.0.2))

Protocol specifications:

* [Hypertext Transfer Protocol Version 2 (RFC 7540)](
RFC 7540 - Hypertext Transfer Protocol Version 2 (HTTP/2))
* [HPACK: Header Compression for HTTP/2 (RFC 7541)](
RFC 7541 - HPACK: Header Compression for HTTP/2)

Here are the updates since the last release:

## 1.1.0

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_bytes` instead of `String#<<`)
* 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

## 1.0.2

### Improvements

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

## 1.0.1

### Improvements

* discard closed streams from the connection (reduces memory consumption).

### Bugfixes

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