LightX-AE 6.0.4.74

Exit the old application before upgrading
- The in-app updater now closes LightX on both Windows and Qt Mac after the existing Save/Discard/Cancel check and a successful installer launch or DMG open request. Canceling the save or failing to start the installer keeps LightX open.
- The Windows installer now honors the updater process ID and waits up to 30 seconds for the old LightX process to exit before replacing files. If exit cannot be confirmed, installation stops without writing the new application files. It does not force-terminate LightX.
- Manual Windows upgrades retain the normal application-close prompt and explicitly check LightX.exe and its runtime DLLs in the selected installation folder.

Qt Mac installation
- Opening the DMG now exits the old Qt LightX application after the save check. You still need to copy LightX.app into Applications and replace the old app, then launch the new version. Opening the DMG alone does not install the update.

Project compatibility
- No changes to RJX projects, captured frames, controller BIN data or licensing. Text toolbar and color-palette improvements from 6.0.4.73 remain included.

Platforms: Windows x64 and LightX Qt for Apple Silicon Mac (macOS 14 or later).

LightX-AE 6.0.4.73

Text editing
- Added a compact text toolbar with installed-font search, recent fonts, size controls, character spacing, bold, italic, underline, strikethrough, superscript, subscript, outline and highlight. Changes apply to the selected text layer and support undo/redo. Locked layers remain protected.
- Added font previews and a system-default option. Missing fonts retain their saved family name and use a local fallback.

Font color
- Added a circular hue/saturation palette with brightness, opacity, HEX/RGB values, presets, text preview and previous/new color comparison.
- Color changes are previewed in the palette. Apply commits one undoable change; Cancel or closing the palette leaves the document unchanged.

Project compatibility
- New optional text styles are saved in RJX and rendered consistently in preview and capture. Existing text defaults and the controller BIN format are unchanged.
- Use this version or a compatible newer version when editing projects with the new styles; older applications may ignore or discard unsupported style fields when saving.

LightX-AE 6.0.4.72

Fixed DXF exports that could report an error or cause AutoCAD to stop responding. Earlier files declared the R2000 (AC1015) format without a complete drawing database. Exports now include consistent standard tables, model-space and paper-space layout associations, object dictionaries, plot-style references, and entity ownership with unique handles.

Lamp points remain unfilled CIRCLE outlines. Cn-Pn port labels and the open center-to-center connection chain from each port to its final lamp are preserved. Lamp coordinates, radii, layer identities, and route order are unchanged. Existing validation and atomic file replacement remain in place.

The complete DXF generated by the updated C++ exporter was confirmed to open successfully in the user's AutoCAD environment. Windows and macOS focused DXF regression checks passed. Previously exported DXF files are not rewritten automatically; export them again after installing this update.

LightX-AE 6.0.4.71

Fixed cloud project opening, previews and thumbnails when mainland delivery routes files to a local replica. Earlier versions could stop at a valid HTTP 302 response and report a service failure although the resource was available.

Resource file requests now follow same-origin redirects, including the HTTP 307 fallback to the authorized primary endpoint if a replica is missing. Redirects are limited to three hops and must keep the original scheme, host and port. Normal API and write requests retain their existing redirect restrictions.

Existing resource permissions, selected project versions, isolated account sessions, cancellation, download size limits, SHA-256 verification and atomic file saving remain in effect. No project or controller protocol format changes are required.

Validated primary and mainland public resource reads, replica fallback, JSON previews, thumbnails, blocked cross-origin redirects, bounded redirect loops and failed-integrity handling. Customer-specific account permissions continue to be enforced by the service.

LightX-AE 6.0.4.70 — Open Local and Cloud Projects

What's new
- Open Project now offers Local RJX and Cloud RJX in one place. The same choices are available from the header and the main menu.
- Cloud RJX opens a project-only resource list. Guests can browse public projects; signed-in users can access projects allowed by their account permissions.
- Cloud originals are downloaded with the selected version, file-size and SHA-256 checks before opening.
- Cloud projects open as editable copies. Downloaded media and frame sources remain available after the browser closes.

Data safety and compatibility
- Canceling source selection leaves the current project unchanged. Unsaved changes still require Save, Discard or Cancel before replacing a project.
- Local RJX opening, legacy project import, and existing cloud access restrictions remain supported.
- The new dialog uses the current LightX theme and provides Chinese and English interface labels.

Web preview note
The resource-center player displays lamp frames captured to Composite. If a project only contains animation layers, capture the animation to Composite, then save a new cloud version to make its patterns playable on the website. An empty pattern list does not by itself mean the original media was lost.

LightX-AE 6.0.4.69 — MP3 素材导入修复

修复问题
Windows 导入部分 MP3 时，会长时间显示“读取素材”，窗口关闭后素材没有加入素材库。已使用可正常播放的4秒、44.1kHz立体声MP3复现：原波形读取请求8kHz单声道PCM，解码器没有输出任何音频缓冲，约30秒后超时；同一文件使用44.1kHz单声道PCM可正常读取。

本次更改
1. Windows 波形读取改用44.1kHz标准采样率，素材中仍仅保存1024个峰值，不将整段PCM存入工程。
2. 素材导入失败时显示明确的错误对话框，并保留界面底部提示，避免只看到读取面板关闭却不知道失败原因。
3. 取消或失败仍不提交部分素材；重复导入继续复用已有素材。
4. Mac 沿用原音频解码器和8kHz波形读取，仅同步共用的导入失败提示。正常系统权限下原Mac版本可导入同一测试MP3，无需修改Mac解码器。

兼容与验证
保留6.0.4.68的Windows大视频管道修复及现有动画、DXF、控制器协议和RJX工程格式。本次对Windows和Mac完整构建进行MP3素材库专项验证，并检查原有音频、视频音轨混合和编辑器操作。Mac安装包完成Developer ID签名、Apple公证及Gatekeeper检查后交付。

边界说明
复现文件为本地生成的测试MP3；客户这次失败的原MP3尚未提供，因此不能声明所有异常MP3均已验证。该修复在6.0.4.69首次交付，6.0.4.68安装包不包含此项更改。保留旧版本安装包供回退。

LightX-AE 6.0.4.68

一、修复 Windows 长视频采集被误判为截断
实际复现素材：1280×752、30 FPS、1278 个视频帧。MP4 文件约 8.52 MB，但解码为 RGBA 原始像素后有 4,920,606,720 字节，超过 4 GiB。Windows 内置 FFmpeg 单独运行能完整输出全部数据；6.0.4.67 的 Windows 采集曾在第 163 个源帧仅读到半帧，实际少收到 4,294,967,295 字节（2³²−1）。因此，压缩视频文件很小，也可能触发大输出缓冲问题。
已核对 Qt 6.11.2 官方 Windows 进程管道实现，其中可用字节数从64位转换为32位 DWORD。消费者采集／缩放较慢、后台积压原始输出过大时，该链路存在计数截断风险。6.0.4.67 的顺序读帧修正解决的是另一类快速定位问题，未覆盖本次 Windows 大缓冲故障。

二、本版处理方式
Windows 视频解码输出改走原生有容量上限的管道。Qt 仍负责启动、退出状态和错误输出；RGBA 原始帧不再进入 Qt 无上限异步 stdout 缓冲。采集消费较慢时，管道向解码器施加背压，避免整段视频的原始像素积压至数 GiB。该适配器同时用于视频检查、完整采集及缩略图等现有解码入口。
Mac 保留原有 Qt 管道路径，并做回归验证。本版不通过补帧、复制尾帧或忽略半帧掩盖失败。真正缺帧、半帧、解码器异常退出、30秒无数据和取消仍会终止任务，保留原有综合结果。

三、验收范围
以原视频测试 128列×125行共16000灯、2048×2000拉伸画布、25 FPS 全长采集与末尾裁剪；另加入超过4 GiB的原始字节流及慢消费者验收，核对准确字节数和内容。工程保存／重开、时间轴同层多片段、属性手动切换、控制器协议容量及中英文错误提示同时回归。
尚未取得客户原工程，不能据此认定客户全部图层、裁剪和关键帧设置均已复现。

四、兼容与保留功能
保留 6.0.4.67 的手动侧栏切换：双击素材加入时间轴、拖入素材、选择图层或新增文字／形状时不自动打开属性；需要时手动点击“属性参数”。同层多片段、顺序离线读帧、Mac音频分析取消修复继续保留。
灯点坐标、FPS、Gamma、RJX容器与工程版本、DXF内容、控制器协议字节顺序不变。6.0.4.67 原安装包保留，本次以独立的 6.0.4.68 升级发布。
