# Jasmine 4.4.0 Release Notes ## Changes * Optimized the process of transitioning between specs in Node, Safari, and Edge. This change reduces the run time of jasmine-core's own test suite by 50-70% in Node, about 20% in Edge, and 75-90% in Safari. Your results may vary. In general, suites with many fast specs will see the greatest performance improvement. * Removed old code to support browsers that don't provide addEventListener/removeEventListener. ## Supported environments jasmine-core 4.4.0 has been tested in the following environments. | Environment | Supported versions | |-------------------|--------------------| | Node | 12.17+, 14, 16, 18 | | Safari | 14-15 | | Chrome | 105 | | Firefox | 91, 102, 104 | | Edge | 104 | ------ _Release Notes generated with _[Anchorman](http://github.com/infews/anchorman)_
