Simplify and optimize the processing of the input stream.
The existing implementation was using bufferUntil and creating a List
for every line along with an EndFrameBuffer inserted for the
bufferUntil predicate. So the larger the input buffer and the more
lines it contained, the greater the overhead.
The new implementation avoids bufferUntil for all lines and
instead uses concatMapIterable to aggregate the lines from a buffer
into a single list. So the larger the input buffer and the more
lines it contains, the better the throughput. The only buffering
used then is for partial chunks and those are accumulated in a list.

This commit introduces support for discovering @Sql, @SqlGroup,
@SqlConfig, and @SqlMergeMode on enclosing classes for @Nested test
classes in JUnit Jupiter.
Closes gh-25913
Includes forPayload methods and common adapter classes for programmatic usage.
Aligns default order values for event handling delegates to LOWEST_PRECEDENCE.
Closes gh-24163
Prior to this commit, references to `JsonGenerator` and
`ByteArrayBuilder` were not closed/released within codecs calls.
This prevents Jackson from reusing more efficiently shared memory
resources.
This commit properly closes/releases Jackson resources in Spring MVC,
Spring WebFlux and Spring Messaging codecs.
A benchmark on WebFlux codecs (in both single value/streaming mode)
shows significant throughput and allocation improvements for small
payloads.
Closes gh-25910
The documentation written for the method WebSocketTransportRegistration.setSendTimeLimit(int timeLimit) mentions that, if no time limit is specified, a default value of 10 seconds is used; however, later on the exact default value employed is incorrectly typed as 10 * 10000 ms, which would result in 100 seconds instead.
The javadoc has been updated in order to show the correct value in milliseconds (10 * 1000).
This commit adds new tasks to the release pipeline, generating release
notes automatically using the issues in the current milestone and
pushing that as the content of the GitHub release.

Before this commit, ReadCompletionHandler delayed closing the channel
to allow an ongoing read to complete/fail so we can get a hold of the
associated DataBuffer and release it. This can be problematic since the
read take time to complete but even more importantly there was a race
condition where we didn't check if we've been disposed concurrently
while releasing the read flag.
This commit removes the delay and closes the channel immediately from
cancel() and that should in turn fail any ongoing read operation,
according to AsynchronousChannel, and the DataBuffer is released.
Further improvements include:
- combining the "reading" and "disposed" AtomicBoolean's into a
single "state" AtomicReference.
- an optimistic check to remain in READING mode and avoid state
switches when there is demand to continue reading.
Closes gh-25831
Prior to this commit only Propagation.NOT_SUPPORTED was supported for
disabling test-managed transactions via the `propagation` attribute of
`@Transactional`.
This commit allows users to specify Propagation.NOT_SUPPORTED or
Propagation.NEVER to disable test-managed transactions.
Closes gh-25909
