12.50 Summer Core Update - durva changelog.

De kiemelnék pár lényeget. Először is a megvalósult álom:

És a korábbi ismert hibák nagy részét kijavították, mint:

DSK-370118 Closed tabs don't go to closed tabs history
DSK-370089 Tabs set to "No images" when upgrading from previous build
CORE-47649 Numpad shortcut keys do not work
DSK-369709 Pressing Enter to select entry from dropdown field doesn't work
DSK-369608 Shortcuts for creating private tab or private window creates 2 tabs or 2 windows
Numerous crash fixes not detailed below
DSK-366433 Opera crashes on Google search

Utóbbit sajnos elég sűrűn tapasztaltam. És pár hasznos teljesítményjavítás:

CORE-45432 Leaving page with many frames takes a long time (temporary freeze)
CORE-46884 Slow performance with CSS3 transitioned images
CORE-37129 High CPU/NSL on some sites (window.constructor is Object object)
CORE-45142 Speed up area traversing with positioned elements
CORE-45284 Freeze when border-left-width or border-right-width is zero
CORE-45383 Slower to parse a function with many integers than it used to be
CORE-44725 Implement assembler optimized versions of pixel handling bottle necks

És ha a specifikációs oldalt jól értelmezem, kell lennie már performance.now()-nak is, mivel a Presto verziószám elég nagyot ugrott. Presto/2.12.362
