Jasmine Core 5.9.0 Release Notes

Bug fixes

• Avoid generating mock clock timer IDs that conflict with native ones
  • Fixes #2068
  • Merges #2069 from @atscott

Deprecations and changes to platform support

• Node versions before 18.20.5 are no longer supported

  Older 18.x versions might still work, but Jasmine is no longer tested in them prior to release.

• Document that the filename properties of suite and spec results are deprecated

  These properties are incorrect in many configurations. They'll be removed in the next major release unless there is enough user interest in fixing them. See https://github.com/jasmine/jasmine/issues/2065.

Internal improvements

• Extensive GlobalErrors refactoring

  • Removed many of the error dispatching differences between browsers and Node
  • Split into portable and platform-specific parts
  • Converted to ES6 classes

• Removed unnecessary errorWithStack helper

  Jasmine no longer runs on platforms that create errors without stack traces.

• Removed protections against user code redefining undefined

  Jasmine no longer runs on platforms that allow redefining undefined.

• Removed rimraf and shelljs dev dependencies
