AWMC Version V26.8.7 [AWMC V2]

New Feature

• Letter board timed settlement — no in-round points/BREAK; after full clear, award by speed stars + contribution; elapsed shown as xx.xxx seconds
• Adaptive star caps — default ≤30/45/60/90/180s; tighten from group history P35 (5★ between 15–30s); settlement shows active thresholds
• Settlement UX — short text (elapsed xx.xxxs + stars + pool) → round split chart → final board; 不玩了 reveals only (no speed/contribution rewards)
• Letter limited ×3 — for one week, letter settlement score & BREAK ×3; text and boards show “限时×3”; auto-reverts to 1× after the event
• Letter boards — 开字母排行 / 开字母贡献榜 / 开字母时间榜
• 我的猜歌 / 猜歌数据 / 猜歌统计 — personal 5-mode (text / jacket / audio / chart / letter) 30-day trend, dual radar, mode cards & recent details; 我的猜歌 @user for others; group 我的AWMC attaches the guess-stats image
• 舞萌状态 / mais — “服务器失败率” chart from full account-operation logs (ticket / maiu / bind; returnCode=0 = failure; empty buckets omitted) plus live Status API
• Guess-chart BGM — precache ending-phase chart video with muxed BGM; rendering isolated from the online bot path

Optimization

• Guess answer rate limit — 2.5 seconds per user globally (text / jacket / audio / chart); over-limit: “嘿嘿，你的答案被我吃掉啦！”
• Letter cooldown — separate 2.5s/user cooldown off-peak (same tip text; independent of global guess limit); skipped in crowded text mode
• Letter text mode — when contributors or short-window burst hits threshold, in-round boards fall back to plain text; clear settlement still forces images
• Guess-chart adaptive concurrency — scale precache/backfill by load; throttle under load so the bot stays responsive
• Unified storage MySQL sync: skip pack when unchanged; reuse unchanged files; startup sync in background
• 我的AWMC / admin 发票统计 show ticket returnCode=0 and null/missing counts

Bug Fix

• Guess-stats chart layout: trend legend/title on separate lines; radar labels pushed out to avoid overlap

Docs / API

• AWMC public API gateway now targets the new upstream: /v1/health, /v1/user/*, /v1/charge, /v1/charge/queue, /v1/update-lx, /v1/update-fish
• keychip is injected server-side; callers only send fields such as qrcode
• Billing requires HTTP 2xx and upstream code === 0; charge enqueue binds mai userId, and the queue is filtered/redacted per account
• Legacy paths (/v1/get_preview, /v1/upload_b50, manual score APIs, etc.) are removed — see developer docs

AWMC Version RELEASE-20260715 V26.8.1 [AWMC V2]

New Feature

• maibindfish / mai绑定水鱼 now supports interactive binding without an argument. The Bot provides the Diving-Fish prober link and guides users to generate and copy an Import-Token from “Edit Profile”
• The Bot keeps waiting after an invalid Shuiyu Token and allows up to three attempts per session; users can send “取消” to exit

Optimization

• Submitted Shuiyu Tokens are recalled first; users are explicitly warned when recall fails
• Successful binding only displays a masked Token and includes a traceable REF_ID
• Shuiyu binding prompts, retries, and results now reply to the triggering message to reduce ambiguity in busy group chats

Bug Fix

• Fixed successful ticket operations being incorrectly reported as FinishedException()
• Fixed the same false-success-error pattern in account, map, queue, and LXNS B50 flows

2026/07/05

New Feature

• maiBot upgraded to V3
• Official bot support
• mai-queue connected to nearcade.com

Optimization

• Due to Shuiyu-related impact, a credit system now limits user API usage

Bug Fix

• Fixed known download site issues
• Fixed index download failures

2026/06/30

New Feature

• 游玩排行50 (游玩PC50 / PC游玩50 / pc游玩50) — Top 50 most-played songs library-wide (image), not limited to Rating B50

Optimization

2026/06/23

AWMC Version PRE-20260623 V26.6.4 [AWMC V2]

New Feature

• 猜曲子 — New group mini-game: 4 stages, 30 seconds of voice per stage, instruments added progressively (drums → drums+bass → +other → +vocals)
• Higher score for earlier correct guesses (10 / 9 / 7 / 5)
• Super users can DM 更新猜曲音频; 更新猜曲音频 -full forces cache rebuild

Optimization

• Guess-audio baking: trim before stem separation to prevent OOM; auto-fallback to ffmpeg when demucs fails; per-song async baking with interrupt support

• Song-guess scoring: daily / weekly / monthly / quarterly / season leaderboards; decreasing score; period settlement archive & history; per-entry settlement messages; combo & banquet filtering
• B15 push recommendations: version detection updated to DX2026「丸」era; fallback to「镜彩」era when CiRCLE missing; multi-level fallback when B15 list is empty
• PC count fetching migrated to sw-api user/music endpoint

Bug Fix

• Guess-song four-stage mixing and stage file validation
• Song-guess answer tolerance regex character class
• Multiple B15 push recommendation filter defects
• sw-api parsing when code=0 and msg is JSON
