v2.6

Website-star sync, compact conference cards, and reliable save recovery · October 8, 2026

Added opt-in CCFDDL conference-star sync through the website’s GitHub login. Connect from the small account icon beside My DDLs; subsequent sync is automatic and the existing refresh button also refreshes stars.
Merged deadlines by conference edition into compact cards. Show the next deadline first, expand stages and rounds, and add all available dates from one import result.
Added calendar and removal actions per stage, plus whole-conference removal. With sync enabled, removing the final saved stage or the whole conference also removes its website star.
Preserved source time zones and stage metadata when parsing conference editions, including fields declared after the timeline.
Serialized local writes and sync commits, retained offline changes, guarded account switches and stale responses, and kept manual deadlines local. No GitHub token entry or additional extension permissions are required.
Fixed save and background-connection errors being reported as local-read failures. Added extension reload for an unavailable background and list refresh before retrying an uncertain save.
Updated the bilingual website, guides, privacy policy and release preview. Expanded popup and sync regression coverage, including browser checks for upgrade recovery and retained data.

Badge scheduling, lighter first-view resources, and more resilient imports.

Replaced minute-by-minute badge polling with one-shot alarms at the next day-count change or expiration, while recalculating immediately after deadline changes.
Bound background local-data reads to 3 seconds and scheduled a single retry after 5 minutes on failure; stale reads and errors cannot overwrite newer badge updates.
Deferred theme initialization and removed synchronous Web Storage access. Saved themes load asynchronously, so system colors may appear briefly.
Preserved the original toolbar clock. Loaded the local YAML/ICS parser only when fetching conferences and added an 84 px popup-header logo asset. First-view files fell from about 203 KB to 109 KB (about 46%); this measures file size, not startup time.
Requested the main conference dataset through direct HTTPS, with independent Chinese and English ICS fallbacks and a 10 second timeout covering each request and response read.
Skipped minute refresh reads while a fallback tracker tab is hidden and refreshed it when visible again.
Added startup timing diagnostics and recovery checks. These improvements do not establish that the long-running browser popup failure is fixed.

Appearance settings, lighter startup, and popup recovery.

Added System (default), Light, and Dark appearance settings, saved locally.
Applied dark colors to cards, forms, settings, import results, and calendar menus.
Initialized time-zone settings on demand, reused date formatters, and combined preferences and deadlines into one startup read.
Added error feedback and Retry for failed or timed-out local reads, without automatically clearing saved data.
Added an Options entry to use the same tracker in a regular tab, plus Chrome and Edge troubleshooting guidance.
Added 11 popup regression tests and initialization timing marks. Startup improvements do not guarantee a fix for browser-level popup failures.

Manual links, remembered input, and footer shortcuts.

Added an optional card link field when manually creating a deadline.
Remembered the last opened add/import panel and unfinished add-form draft between popup opens.
Changed the default countdown display to include hours and minutes.
Refined footer shortcuts for GitHub, the extension home, and CCFDDL.
Added CCF category and ranking metadata to the import list for easier conference browsing.
Added an optional setting to show conference metadata on saved cards.
Included conference metadata in Google Calendar and ICS exports.

Right-click calendar actions.

Added a right-click context menu for deadline cards in the popup.
Added direct export to Google Calendar from saved or imported deadline items.
Added Apple / iCloud compatible .ics export and a generic ICS download action.
Fixed list deletion so removing an item still targets the correct deadline after sorting.

Time zone switching and import time handling.

Added a popup time zone selector with Asia/Shanghai as the default display zone.
Manual deadlines now save against the currently selected time zone instead of the browser local zone.
Imported CCFDDL deadlines keep their source time zone semantics when displayed.
Improved ICS fallback parsing so TZID-based timestamps are handled correctly.

UI overhaul, import improvements, settings, and versioning.

Reworked the popup into a denser layout with two entry cards and a bottom utility bar.
Kept the import panel visible by default while moving recommendations into a floating search picker.
Imported conferences now keep homepage links and added cards can open the official conference site.
Added display settings for 24-hour or 12-hour time and year-first or month-first date order.
Added a v2.0 version label in the popup header and bumped the extension version.

Refresh and remaining-day fixes.
