Added

Support for PHP 8.
Type signatures and strict type enforcement.
Less member variable boilerplate via constructor property promotion.
Type signatures for Serialized handlers.
Compatibility with XDebug 3.
Docker containers for quick interaction: try composer docker-build and composer docker-run.

Removed

Support for PHP 7 and earlier.
Spurious use of Monolog\StreamHandler.
$isUncaught parameter on Rollbar::log; replaced with Rollbar::logUncaught.
Use of call_user_func and call_user_func_array internally.
Monolog 1 handler.

The performance test suite now runs to completion with assertions on the expected run-time performance within GitHub actions. Running these on different hardware configurations may not match the expectations, so care should be taken to match test platform specifications when reporting performance issues. A future version may provide better direction as to the required test platform specifications.
Missing URL encoding when internally calling the Rollbar occurrences API.
Uncaptured local variables when using the zend.exception_ignore_args=Off engine configuration.

The new configuration option scrub_safelist replaces the deprecated scrub_whitelist configuration option, which is now removed.
The check_ignore configuration option, if defined and containing the name of an invocable function, will now catch thrown \Error -- division by zero, parse and type errors, assertion failures, etc. Before, only thrown \Exception would be caught.
In the event the API rejected an occurrence during a log() call, and no message was available, the new default message reads "message not set": before this was misspelled as "mesage not set".
AgentSender::sendBatch() no longer returns a value, as it was inconsistent with the interface. To access the return values, pass a return-by-reference variable as the third argument to AgentSender::sendBatch.
