+
+Remove tagged logging support from `Appsignal::Logger`.
+
+Tagged logging is still supported by wrapping an instance of `Appsignal::Logger` with `ActiveSupport::TaggedLogging`:
+
+```ruby
+appsignal_logger = Appsignal::Logger.new("rails")
+tagged_logger = ActiveSupport::TaggedLogging.new(appsignal_logger)
+Rails.logger = tagged_logger
+```
+
+Removing this functionality allows for a workaround to issues within Rails ([#49745](https://github.com/rails/rails/issues/49745), [#51883](https://github.com/rails/rails/issues/51883)), where using the broadcast logger to log to more than one tagged logger results in incorrect behaviour of the tagged logging methods, resulting in breakage throughout Rails' internals:
+
+```ruby
+# We use the built-in request ID middleware as an example that triggers
+# the issue:
+Rails.config.log_tags = [:request_id]
+
+appsignal_logger = Appsignal::Logger.new("rails")
+tagged_logger = ActiveSupport::TaggedLogging.new(appsignal_logger)
+
+# This does not work correctly, because the default `Rails.logger` is a
+# broadcast logger that is already broadcasting to a tagged logger.
+# When asked to broadcast to a second tagged logger, the return value of
+# `Rails.logger.tagged { ... }` will be incorrect, in turn causing the
+# `RequestID` middleware, which uses it internally, to return broken
+# Rack responses.
+Rails.logger.broadcast_to(tagged_logger)
+```
+
+By reverting the changes to our logger so that it is no longer a tagged logger, we enable a workaround to this issue:
+
+```ruby
+Rails.config.log_tags = [:request_id]
+
+appsignal_logger = Appsignal::Logger.new("rails")
+
+# This works correctly, because `appsignal_logger` is not a tagged logger.
+# Note that `appsignal_logger` will not have the `request_id` tags.
+Rails.logger.broadcast_to(appsignal_logger)
+```
