Highlights
*
Added user interface for built-in crash reporting. Please remember to
add any relevant details before sending the report (only Windows for
now)
* Turbo mode is now disabled automatically for local IP addresses and hostnames
*
Work on adding a placeholder image for plugins that are missing or not
loaded (in Turbo mode) - see the "extras" folder for the SVG file
*
Google TLD server work. On first run, we contact a Google server, and
it returns the correct top level domain (TLD) to use (google.ru for
Russia, google.no for Norway, and so on)
* Show sent mail when using threading in the e-mail client
* Updated Presto version to 2.2.2
* Some improvements for skin designers:
1)
Added "Reload skin" action, which can be assigned to a keyboard
shortcut in the shortcut editor (e.g. "F5 ctrl" - "Reload skin" under
the "Application" section)
2) You can point to an unzipped skin by
adding the full path to the skin.ini file in
opera:config#UserPrefs|ButtonSet (use the "Reload skin" action after
changing the setting)
3) Toolbar.ini defines new button skins for
each toolbar, so each toolbar can be skinned separately. Fallback is
Toolbar Button Skin. (Known issue: Native skins not updated yet, so
they will get the hover state for the default skin instead)
