Hi, this is Greg, bringing you the latest news from the Rails world.

Add ability to ignore tables by a regular expression for SQL schema dumps

Make validators accept lambdas without record argument
Now you can set validators without passing the object to the lambda like this: validates_comparison_of :birth_date, less_than_or_equal_to: -> { Date.today }

Fix using helpers in content_security_policy and permissions_policy
Helpers that are generated using helper_method were not possible to use in content_security_policy and permissions_policy, because the use of yield caused self to be set incorrectly. But by using instance_exec, this PR ensures the scoping is correct.

Add db_runtime to Active Job instrumentation
This PR adds db_runtime to the notification payload of a perform.active_job event. db_runtime tracks the total time taken by database queries while performing a job, which helps in understanding how a job's time is spent.

More details to several HTTP Security Headers in guides
Some improvements to the security related HTTP headers in the guides.

Introduce config.log_file_size
