Pebble SDK 3.6 - Changelog

Release Date: October 14 2015

This changelog contains all changes since SDK 3.4. SDK 3.5 was never shipped.

Known Issues

• Unfocused menu layer cells on Chalk may have their content inappropriately truncated. This behavior will improve before Pebble Time Round is released.

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 24 pixels).
• Improved backlight behavior when dictating text.
• Added support for 8 KiB AppMessage buffers.

Changes to SDK

• Added the new "Chalk" platform for the Pebble Time Round.
• Added the Dictation API, enabling voice input on the Basalt and Chalk platforms.
• 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 default configuration for menus on Chalk.
• Added menu_layer_is_index_selected.
• Added constants for the heights of menu cells on Chalk: MENU_CELL_ROUND_FOCUSED_SHORT_CELL_HEIGHT, MENU_CELL_ROUND_FOCUSED_TALL_CELL_HEIGHT, MENU_CELL_ROUND_UNFOCUSED_SHORT_CELL_HEIGHT and MENU_CELL_ROUND_UNFOCUSED_TALL_CELL_HEIGHT.
• Added DEG_TO_TRIGANGLE, the inverse of the pre-existing TRIGANGLE_TO_DEG.
• Added GBitmapFormat8BitCircular, the new framebuffer format used on Chalk.
• Added gbitmap_get_data_row_info, because GBitmapFormat8BitCircular does not have a constant number of bytes per row. This should now be used for all framebuffer manipulation.
• Added the GTextAttributes structure, with methods for defining text flow and paging on a circular display.
• Added support for GTextAttributes to graphics_draw_text. That NULL parameter that you've been tacking on the end for two and a half years now actually does something.
• Added methods to TextLayer for flowing and paging text on a circular display.
• Added paging support to ScrollLayer.

Changes to Pebble Tool

• Added support for Chalk and circular displays.
• Added the pebble transcribe command, enabling testing dictation in the emulator.
• Added the pebble data-logging command, to download stored datalogging from the watch to the computer.
• Added the pebble emu-time-format commmand, allowing switching of the emulator between 12-hour and 24-hour formats.

Changes to Emulator/Phonesim

• Added support for Chalk and circular displays.
• Fixed a JavaScript runtime crash when sending non-ASCII characters by AppMessage.
