Safari Technology Preview – Release 2 veröffentlicht

Apple hat am gestrigen Abend das zweite Release seiner Safari Technology Preview veröffentlicht. Damit läutet man auch in der Browser “Beta” für Macs den zweiwöchigen Testzyklus ein!

2016-04-14-06_31_10-Safari-Downloads-Apple-Developer-772x177 Safari Technology Preview - Release 2 veröffentlicht Software Technologie Web

Erst vor zwei Wochen hatte Apple seiner Entwickler Community die neue Preview – also quasi die Beta – des OS X Browsers an die Hand gegeben, mit der man die neuen Web-Technologie austesten kann. Nun folgt also die zweite Version, welcher wieder eine ganze Hand voll Fehler beheben soll.

Die Safari Technology Preview kann neben der normalen und standardmäßigen Safari Version installiert werden. Somit habt ihr selbst als Nicht-Entwickler die Möglichkeit zu wählen, ob ihr mit der Beta oder mit der finalen Browserversion surfen wollt. Das aktuelle Update enthält Änderungen in den Bereichen JavaScript, CSS, Web APIs, Web Inspector, Rendering, Medien, Netzwerk und so weiter. Solltet ihr Interesse daran haben, könnt ihr das Installationspaket auch ohne Developer Account auf der Entwicklerwebsite von Apple herunterladen.

Das volle Changelog dazu gibt es hier:
