Apple har släppt en ny version av det som kallas Safari Technical Preview – en förhandsversion av den kommande versionen av webbläsaren.
Det intressanta med den här nya versionen är att den innehåller prestandaförbättringar – som faktiskt syns vid vanligt användande. Innan du kastar dig över webbläsaren så kom ihåg – det är en testversion som kan innehålla buggar så du kör den på egen risk.
Den här versionen innehåller förutom prestandaförbättringar hela 104 listade buggfixar – merparten torde återfinnas i den kommande skarpa versionen av Safari, längre fram.
