Pebble SDK 3.6-dp2 - Changelog	2015-09-23

This changelog collects only changes visible to developers using the emulator. A complete changelog will be provided when 3.6 ships on physical watches.

Changes to Firmware

• Added support for circular watches.
• Window stack animations were disabled on Chalk.
• Adjusted the display of ActionBarLayers for circular watches.
• Adjusted the display of ActionMenus for circular watches.
• Increased the height of the StatusBarLayer on Chalk (16 to 20 pixels).

Changes to SDK

• Added the new "Chalk" platform for the Pebble Time Round.
• Added PBL_ROUND, PBL_RECT and PBL_PLATFORM_CHALK defines.
• Added PBL_IF_ROUND_ELSE, PBL_IF_RECT_ELSE, PBL_IF_COLOR_ELSE and PBL_IF_BW_ELSE macros. COLOR_FALLBACK is now considered deprecated.
• Added graphics_fill_radial and graphics_draw_arc, for drawing partial circles.
• Added gpoint_from_polar and grect_centered_from_polar for conversion from polar to cartesian coordinates.
• Added ContentIndicator, which provides a visual indicator of content above or below the display.
• Added menu_layer_set_center_focused, which forces the highlighted menu item to always be in the center of the display. This is the preferred configuration for menus on Chalk.
• Added DEG_TO_TRIGANGLE, the inverse of the pre-existing TRIGANGLE_TO_DEG.
• Added GBitmapFormat8BitCircular, the new framebuffer format used on Chalk.
