[1.3.0] — 2026-06-13

Added

• Challenge experience and levels. Every challenge now grants XP scaled on its difficulty (points x10, hidden challenges x15). A golden artifact-style level ring sits in the Challenges summary with your level, a thin XP bar and the count of challenges earned this month. A level-up toast announces each new level (preview with /gs dev levelup).
• Level milestones. Levels 5/10/15/21 unlock a title shown in the Challenges banner ("Good comrade" → "Group legend") and tint the level ring along the WoW rarity ladder (green → blue → epic purple → legendary orange); at the top milestone the minimap button turns gold.
• Seasonal challenges under a collapsible "Midnight" category. 33 challenges per Mythic+ season (timed keys, runs, recommendations, flawless runs, encounters, notes, raid bosses, timed streaks...). The expansion category folds/unfolds with a hand-drawn +/- marker, seasons sit indented under it, and Season 2 is already prepared: its category appears automatically when the new season starts, while Season 1 stays visible and frozen with everything you earned.
• Season 1 backfill. Since the addon was born in Season 1, your existing history (timed keys, recommendations, encounters, notes, flawless runs, streaks...) seeds the seasonal counters, so challenges you have effectively met validate immediately.
• Challenge sharing in chat. Shift-click a challenge tile to share it; for addon users the token becomes a clickable achievement-style link. Clicking it opens a movable toast-style mini window (drag to move, close with the X or a right click; left click opens the tile). A shared hidden challenge the receiver hasn't earned shows only a "Mysterious challenge" panel — no spoilers, and the link itself carries an opaque hash, never the secret's id.
• Hover shine everywhere. Challenge category buttons, tiles (gold when unlocked, cool blue when locked) and toasts now glow on hover; toasts also hold while hovered. The settings categories use Blizzard's exact active/hover highlight.

Changed

• "This week / this month" stats now reset on real boundaries: the week follows your region's Mythic+ weekly reset, the month resets on the 1st (they were rolling windows before).
• The challenge summary shows up to 6 recent unlocks in two columns and the banner no longer repeats the total already shown on the KPI card.
• French wording: timed keys now read "dans les temps" (proper M+ phrasing).

Fixed

• "Marathon runner" was nearly impossible: it counted runs from a 14-day cache; it now uses a cumulative counter (seeded from your known runs).
• A hidden Season 2 no longer leaves a hole that pushed the Mysteries button out of the category frame; the frame now resizes with its visible buttons.
• The shared-challenge window close button sits properly in the corner, and toast titles sit slightly lower on the gold strip.
