0.21.0

Breaking Changes:

• Bump the minimum required Rust version to 1.42.0.
• The actix integration / middleware is now compatible with actix-web 3.
• Removed all deprecated exports and deprecated feature flags.
• The failure integration / feature is now off-by-default along with its deprecation.
• The log and slog integrations were re-designed, they now offer types that wrap a log::Log or slog::Drain and forward log events to the currently active sentry Hub based on an optional filter and an optional mapper.
• The new log integration will not implicitly call log::set_max_level_filter anymore, and users need to do so manually.

Features:

• The SDK will now set a default environment based on debug_assertions.
• Session updates are now sent lazily.
• Add the new end_session_with_status global and Hub functions which allow ending a Release Health Session with an explicit SessionStatus.

Deprecations:

• The error-chain and failure integration was officially deprecated and will be removed soon.
