Replace legacy WebDAV opaquelocktoken: scheme for lock tokens with urn:uuid: as recommended by RFC 4918, and remove secret init parameter. (remm)
Concurrent reads and writes (e.g. GET and PUT / DELETE) for the same path caused corruption of the FileResource where some of the fields were set as if the file exists and some were set as if it does not. This resulted in inconsistent metadata. (markt)
69415: Ensure that the ExpiresFilter only sets cache headers on GET and HEAD requests. Also skip requests where the application has set Cache-Control: no-store. (markt)

Coyote

Correct a regression in the fix for non-blocking reads of chunked request bodies that caused InputStream.available() to return a non-zero value when there was no data to read.

Correct the date format used with the expires attribute of HTTP cookies. A single space rather than a single dash should be used to separate the day, month and year components to be compliant with RFC 6265. (markt)
Include the name of the current stream state in the error message when a stream is cancelled due to an attempt to write to the stream when it is in a state that does not permit writes. (markt)
NIO writes never return -1 so refactor CLOSED_NIO_CHANNEL not to do so and remove checks for this return value. Based on #562 by tianshuang. (markt)
Remove unnecessary code that exposed the asyncTimeout to components that never used it. (markt)
Ensure that all MessageBytes conversions to byte arrays are valid for the configured character set and throw an exception if not. (markt)
When an HTTP/2 stream was reset, the current active stream count was not reduced. If enough resets occurred on a connection, the current active stream count limit was reached and no new streams could be created on that connection. (markt)

Jasper

66294: Make the use of a privileged block to obtain the thread context class loader added to address 62080 optional and disabled by default. This is now controlled by the org.apache.el.GET_CLASSLOADER_USE_PRIVILEGED system property. (markt)
