Full Release Notes

Technically a breaking change, the `Send` implementation is removed from
`runtime::EnterGuard`. This change fixes a bug and should not impact most users.

### Breaking

- rt: `EnterGuard` should not be `Send` ([#5766])

### Fixed

- fs: reduce blocking ops in `fs::read_dir` ([#5653])
- rt: fix possible starvation ([#5686], [#5712])
- rt: fix stacked borrows issue in `JoinSet` ([#5693])
- rt: panic if `EnterGuard` dropped incorrect order ([#5772])
- time: do not overflow to signal value ([#5710])
- fs: wait for in-flight ops before cloning `File` ([#5803])

### Changed

- rt: reduce time to poll tasks scheduled from outside the runtime ([#5705], [#5720])

### Added

- net: add uds doc alias for unix sockets ([#5659])
- rt: add metric for number of tasks ([#5628])
- sync: implement more traits for channel errors ([#5666])
- net: add nodelay methods on TcpSocket ([#5672])
- sync: add `broadcast::Receiver::blocking_recv` ([#5690])
- process: add `raw_arg` method to `Command` ([#5704])
- io: support PRIORITY epoll events ([#5566])
- task: add `JoinSet::poll_join_next` ([#5721])
- net: add support for Redox OS ([#5790])


### Unstable

- rt: add the ability to dump task backtraces ([#5608], [#5676], [#5708], [#5717])
- rt: instrument task poll times with a histogram ([#5685])
