(boost_gh:issue[parser,278]).
** Correct many, many typos in the docs (boost_gh:pr[parser,271]).
* boost_phrase:library[Redis,/libs/redis/]:
** Important changes to *cancellation*:
*** Improved the per-operation support in `async_exec()`, and added
support for `asio::cancel_after`. Requests can now
be cancelled at any point, and cancellations don't interfere with other
requests anyhow.
Pull requests boost_gh:pr[redis,310] and boost_gh:issue[redis,226].
*** Deprecated the `cancel_on_connection_lost` and `cancel_if_not_connected`
flags in `request::config`.
To limit the time span that `async_exec`
might take, use `asio::cancel_after`, instead.
`cancel_on_connection_lost` default has been changed to `false`.
Pull requests boost_gh:pr[redis,329] and boost_gh:pr[redis,334].
*** Deprecated calling `cancel` with `operation::resolve`, `connect`,
`ssl_handshake`, `reconnection` and `health_check`.
Users should employ `cancel(operation::run)`, instead.
Pull request boost_gh:pr[redis,321].
*** Added support for per-operation cancellation in `async_run()`.
Issue boost_gh:issue[redis,319].
** Added support for *custom setup requests* using `config::setup`.
When setting these fields, users can
replace the library-generated `HELLO` request by any other arbitrary request.
Issue boost_gh:issue[redis,302] and pull request boost_gh:pr[redis,303]. +
** Deprecated `request::config::hello_with_priority`.
If you need to execute a request before any other, use `config::setup`, instead.
Pull request boost_gh:pr[redis,305].
** *Valkey* long-term support: we guarantee Valkey compatibility
starting with this release.
Issue boost_gh:issue[redis,296].
** Added a `request::append()` function, to concatenate request objects.
Issue boost_gh:issue[redis,341].
** The health checker algorithm has been redesigned to avoid
false positives under heavy loads. `PING` commands are now
only issued when the connection is idle, instead of periodically.
Issue boost_gh:issue[redis,104].
** Added `config::read_buffer_append_size`, which allows to control
the expansion of the connection's read buffer.
Pull request boost_gh:pr[redis,283].
** Added `usage::bytes_rotated`, which measures data copying when
reading and parsing data from the server.
Pull request boost_gh:pr[redis,311].
** Bug fixes:
*** Fixed a bug causing an exception to be thrown when parsing
a response that contains an intermediate error into a `generic_response`.
Issue boost_gh:issue[redis,287].
*** Fixed a number of race conditions in the `cancel()` function
of `connection` and `basic_connection` that could cause
cancellations to be ignored.
Issue boost_gh:issue[redis,318].
*** Users with an empty password but a non-default username are
now correctly authenticated. Issue boost_gh:issue[redis,298].
*** Fixed a problem that could cause an error during `HELLO`
to make subsequent `HELLO` attempts during reconnection to fail.
Issue boost_gh:issue[redis,290].
*** Errors during `HELLO` are now correctly logged.
Issue boost_gh:issue[redis,297].
* boost_phrase:library[SmartPtr,/libs/smart_ptr/]:
** The functionality enabled by the deprecated macros
`BOOST_SP_ENABLE_DEBUG_HOOKS`, `BOOST_SP_USE_STD_ALLOCATOR`,
