Sourced from guzzlehttp/psr7's releases.

2.10.4

Fixed

• Apply UriNormalizer percent-encoding normalizations to URI fragments
• Make LimitStream::getSize() return 0 for slices past the underlying stream end
• Make AppendStream::read() return an empty string when no streams are attached
• Make CachingStream::read() throw on an incomplete cache-target write instead of silently corrupting replays
• Prevent CachingStream::seek() from looping indefinitely when the remote stream makes no progress

2.10.3

Fixed

• Fixed URI parsing for IPv6 literals containing embedded IPv4 addresses
• Fixed malformed UTF-8 URI strings being parsed as empty URIs

2.10.2

Security

• Reject control and whitespace characters in URI host components (GHSA-hq7v-mx3g-29hw)
• Reject malformed Host values when constructing request URIs (GHSA-34xg-wgjx-8xph)

Fixed

• Make ServerRequest::fromGlobals() robust against unexpected HTTP header value types in $_SERVER
