本版更新 / What's new (v1.2.4-beta.2)

Beta 測試版 / Beta build: 本版包含逐 AP 局部選幀與輸出後處理等大型變更，請先保留原始素材與既有輸出。 / This build contains substantial per-AP selection and output-processing changes; keep your source data and previous outputs while testing.

• Global RGB 樣板對齊新增低訊號遮罩：自動忽略中央量測區域中的大面積近黑／無資料像素，降低背景或拼接邊界造成的誤對齊。 / Global RGB template alignment now auto-masks large near-black or no-data regions in its measurement ROI, reducing mistracks caused by background or mosaic borders.

• Global RGB 的量測範圍改為涵蓋所有啟用 AP 完整視窗的方框，與穩定化 anchor 脫鉤；Drizzle 時會同步縮放 AP 座標。 / The Global RGB measurement ROI now covers the full windows of all enabled APs, independently of the stabilization anchor, with AP coordinates scaled for Drizzle output.

• 對齊前 Gaussian pre-blur 的預設 sigma 改為 2.0，提升雜訊影格的對齊穩定性；僅作用於位移估算，不影響疊圖細節與清晰度選幀。 / The default pre-alignment Gaussian blur sigma is now 2.0 for steadier tracking on noisy frames; it affects shift estimation only, not stacked detail or sharpness-based selection.

• 輸出 TIFF 的文字 sidecar 新增實際 RGB 對齊結果：Global RGB 記錄 R/B 位移與 response，poly／mesh 記錄各通道 AP 統計、RMS、最大位移及是否套用。 / TIFF text sidecars now include actual RGB alignment results: R/B shifts and responses for Global RGB, and per-channel AP statistics, RMS, maximum displacement, and applied status for poly/mesh modes.

• Local Select 改為真正逐 AP 獨立選幀：每個對齊點各自選擇局部最清晰的影格，並以網格重心權重平滑融合，支援一般網格疊合、彩色、Drizzle 與 Bayer Drizzle。 / Local Select is now genuinely per-AP: every alignment point independently selects its locally sharpest frames, blended smoothly with mesh barycentric weights across plain mesh, colour, Drizzle, and Bayer Drizzle paths.

• 新增 COG 輸出置中：使用 COG 穩定化時，可在 Auto Crop 後將亮度重心移至輸出中央；預設開啟，Phase 穩定化會自動略過。 / Added optional COG output centering after Auto Crop; enabled by default for COG stabilization and automatically skipped for Phase stabilization.

• AP overlap 移至主畫面 AP size 旁，預設改為 0.75；Mesh warp smoothing 預設改為 0.025；Debayer 預設改為 VNG；Frame Select 與 Local Select 預設皆為 100%。 / AP overlap moves beside AP size on the main panel and defaults to 0.75; mesh-warp smoothing defaults to 0.025; debayer defaults to VNG; Frame Select and Local Select both default to 100%.

• 輸出 TIFF 的文字 sidecar 現在記錄完整 PipelineConfig、所有主畫面參數、來源 metadata、實際選取影格索引與 AP 座標，提升處理結果的可重現性。 / TIFF text sidecars now record the complete PipelineConfig, every main-panel parameter, source metadata, selected frame indices, and AP coordinates for improved reproducibility.

• 修正彩色 Drizzle 勾選 coverage map 時，在疊合完成後出現「too many values to unpack」的錯誤，並補強逐 AP 路徑的記憶體估算與 worker 限制。 / Fixed the post-stack “too many values to unpack” failure when saving colour-Drizzle coverage maps, and strengthened RAM estimates and worker limits for per-AP paths.

• AP 預覽燈泡圖例新增淡灰色箭頭說明：代表偏差校正前的原始量測位移；彩色箭頭則為實際用於疊合的校正後位移。 / The AP overlay legend now explains the dim-grey raw pre-bias shift arrow versus the corrected coloured shift used for stacking.

先前更新 / Earlier (v1.2.3)

• 新增檢查更新功能：可從 Help 選單手動檢查，打包版啟動時也會安靜檢查一次（可在進階設定的「更新」分頁關閉）。僅讀取公開的發行清單、不會上傳任何資料；離線或連線失敗時自動略過。 / New check-for-updates: check manually from the Help menu, and packaged builds also do one quiet check on startup (opt-out under the Advanced Settings "Updates" tab). It only reads the public release list, uploads nothing, and silently skips when offline.
• 一般（非 drizzle）網格疊合新增記憶體預檢保護；原「Drizzle RAM limit」設定更名為通用的「RAM usage limit」，同時涵蓋 drizzle 與一般疊合路徑。 / Plain (non-drizzle) mesh stacking now gets the memory pre-flight guard; the former "Drizzle RAM limit" setting is renamed to the general "RAM usage limit" and governs both the drizzle and plain stacking paths.
• 修正自動佈點等作業完成時，進度視窗卡在「Cancelling…」而無法關閉的問題。 / Fixed the progress window getting stuck on "Cancelling…" (and refusing to close) when Auto Place and similar operations finished.

先前更新 / Earlier (v1.2.2)

• 新增手動排除幀功能：可在預覽中逐一切換排除任意數量的低品質幀，被排除的幀不參與疊合，並於品質圖上以洋紅色方框標示。 / New manual frame rejection: toggle any number of frames out of the stack from the preview; rejected frames are excluded regardless of quality and marked with magenta squares on the quality chart.
• 新增手動選擇參考幀：可將預覽中的幀固定為疊合／自動佈點的參考幀，覆蓋預設（品質最高幀）；批次處理仍自動挑選。 / New manual reference-frame selection: pin the previewed frame as the stacking / auto-AP reference, overriding the default (highest-quality frame); batch still auto-picks per file.
• 對齊點自動佈點改用 Lloyd CVT（重心 Voronoi）分佈，點位更均勻，並可設定晶格與邊緣保留距離。 / Auto AP placement now uses Lloyd CVT (centroidal Voronoi) for more even coverage, with configurable lattice and edge keep-out.
• 網格扭曲新增邊界錨環與外插模式，並新增「AP 位移離群拒斥 k」設定（k=0 可停用），未受信任的點以鄰近平均填補。 / Mesh warp adds a boundary anchor ring with extrapolate mode, plus an "AP shift outlier reject k" setting (k=0 disables); untrusted APs are filled with the neighbour mean.
• 次像素對齊改用 2D 高斯峰值擬合，降低像素鎖定（pixel-locking）；並新增對齊前高斯模糊（pre-blur）選項。 / Sub-pixel alignment now uses a 2D Gaussian peak fit to curb pixel-locking, with a new optional pre-alignment Gaussian blur (pre-blur).
• 色彩對齊「Global RGB」新增樣板比對法並設為預設，poly／mesh 模式沿用亮度疊合的對齊點，並拒斥不合理的 RGB 位移。 / "Global RGB" colour align gains a template-matching method (now default); poly/mesh modes reuse the luma stack's APs, and implausible RGB shifts are rejected.
• 品質排名會拒斥裁切／出框的行星影格。 / Quality ranking now rejects clipped / off-frame planets.
• 進度對話框（含批次）新增預估剩餘時間（ETA）。 / Progress dialogs (including batch) now show an estimated time remaining (ETA).
• 修正 Windows 上影格索引輸入框過窄、看不到數字的問題。 / Fixed the frame-index spin box being too narrow to show its digits on Windows.
• 預覽區可縮到影像最小寬度，設定／預覽分隔線拖動更順暢。 / The preview column can now shrink to the image's minimum width, so the settings/preview splitter drags smoothly.
• 隨附第三方授權資訊，符合 PySide6/Qt LGPL 規範。 / Bundled third-party license information for PySide6/Qt LGPL compliance.

系統需求與注意事項 / Requirements & notes

Windows

• Windows 10 / 11 (64-bit)。
• 解壓後執行資料夾內的 MapStacker.exe，不需另外安裝 Python。
• 若提示缺少 VC++ 執行庫，請安裝 Microsoft Visual C++ Redistributable（近代 Windows 多半已內建）。
• Unzip and run MapStacker.exe; no separate Python install needed. If a missing
  VC++ runtime is reported, install the Microsoft Visual C++ Redistributable.

Linux

• 需 glibc ≥ 2.31（Ubuntu 20.04+、Debian 11+ 或同等發行版）。
• 解壓後執行資料夾內的 MapStacker。圖形介面使用 Qt xcb，在純文字環境或缺少 X11 的情況下無法啟動。
• Requires glibc ≥ 2.31 (Ubuntu 20.04+, Debian 11+). Unzip and run MapStacker.
  The GUI uses the Qt xcb plugin and will not start in a headless / X11-less environment.

macOS

• 僅提供 Apple Silicon (arm64) 版；Intel Mac 不支援。
• 因 app 未簽章，首次開啟若被 Gatekeeper 阻擋，請右鍵 →「打開」，或到「系統設定 → 隱私權與安全性」放行。
• Apple Silicon (arm64) only; Intel Macs are not supported. The app is unsigned —
  if Gatekeeper blocks the first launch, right-click → "Open".
