This release contains more changes to unpoly-migrate.js Show archive.org snapshot to help upgrading from Unpoly 2 to 3:

• Deprecation warnings for renamed attributes now always mention the actual attribute name instead of the parsed render option.

  For example, the deprecation warning for [up-reveal] used to say:

  Option { reveal: true } has been renamed to { scroll: "target" }
  

  This wasn't very helpful for tracking down affected code. The warning has been changed to this:

  Attribute [up-reveal] was renamed to [up-scroll="target"].
  

• Using the deprecated up.element.toggleClass() Show archive.org snapshot now logs a deprecation warning.

• Using the deprecated up.$compiler() Show archive.org snapshot now logs a deprecation warning.

• Using the deprecated up.$macro() Show archive.org snapshot now logs a deprecation warning.

• Using the deprecated up.$on() Show archive.org snapshot now logs a deprecation warning.

• Using the deprecated up.$off() now logs a deprecation warning.

• Using the deprecated up.scroll() Show archive.org snapshot now logs a deprecation warning.

• up.form.config.groupSelectors Show archive.org snapshot now also removes the suffix :has(&) in addition to :has(:origin).

• When disabling log formatting with up.log.config.format = false Unpoly no longer prints structured objects to the console. This makes it easier to detected use of undeprecated APIs with automated tests Show archive.org snapshot .
