DeskBox 1.5.4

DeskBox 1.5.4 is a reliability update for large batch operations in file widgets: memory no longer climbs and stays high, the cut-out freeze is gone, and the undo history inside settings.json is finally bounded. It ships the performance and safety work from pull requests #386, #388, #390, #391, and #393.

Released on September 18, 2026.

Highlights

• Keep memory in check after large batch operations. Importing, organizing, or cutting thousands of files no longer leaves private memory near 1 GB with no recovery until restart. Settings persist by streaming straight into the store temp file instead of materializing multi-megabyte buffers, and moving files out of a widget stops triggering thousands of debounced saves.
• Stop the cut-out freeze. Cutting a large selection out of a widget used to run the cut-state sweep once per collection event, producing a visible storm of list updates; it now runs once per batch.
• Bound the undo history in settings.json. The history previously had no per-batch limit, so repeated multi-thousand-file operations could grow settings.json without bound (a real profile reached 19.8 MB, inflating every save and every startup). Batches beyond the receipt limits keep their history entry as a summary — real item count, never a partial undo — and existing bloated profiles shrink automatically on the first launch after updating (the 19.8 MB profile migrates to under 100 KB with all 24 entries preserved).
• Speed up large widget operations. Imports and watcher reloads use a scoped path index with binary insertion instead of per-file list scans.
• Harden the batch transaction boundaries. Recovery journals, undo receipts, and abandon markers follow checked-durable ordering, so a crash or a save failure during a large batch can no longer restore already-committed files back to the desktop or drop an abandon.

Downloads and verification

GitHub Releases installers

The direct installers are Full Native AOT builds with the bundled private Windows App Runtime for offline installation. Installers are currently unsigned; verify the SHA-256 checksums after downloading. Matching .sha256 sidecars accompany both installers.

Microsoft Store upload

The combined .msixupload will be submitted to Partner Center. It contains DeskBox_1.5.4.0_x64_arm64.msixbundle and the matching x64 and ARM64 .appxsym files. The internal bundle has version 1.5.4.0 and SHA-256 619D589FB6C1CACB7ECFD7ACDFB71F4562DF3D83BFC94ABB4231467356FB9D87. The single-architecture outputs are intermediate build evidence, not the submission artifact.

Source baseline: d945f3725c9f1fc71a1cb54bfdb57ee696a1fb7c on main.

Validation

• x64 regression suite: 3722/3722 passed on 2026-09-18.
• Native AOT Release memory curve (isolated data root): four large-batch rounds converge to a ~490 MB plateau with marginal growth decaying from +20% to +2.3%; the managed heap stayed at ~35 MB and the #388 cut-out storm did not reproduce. Baseline idle was 128 MB.
• Upgrade-path check: a real 19.8 MB settings.json migrated automatically to 92.9 KB on first launch with all 24 history entries preserved (full-application run).
• Combined Store container and both architecture audits passed: bundle identity/version, architecture coverage, symbol files and inner-package hashes verified.

中文说明

DeskBox 1.5.4 是一次针对文件格子大批量操作的可靠性更新：内存不再攀升后高居不下、剪切大量文件不再卡顿，settings.json 中的撤销历史终于有了上限。本版包含 PR #386、#388、#390、#391、#393 的性能与安全工作。

发布日期：2026 年 9 月 18 日。

主要更新

• 大批量操作后内存不再高居不下。 导入、整理或剪切数千文件不再让私有内存逼近 1 GB 直到重启：设置持久化直接流式写入临时文件，不再生成数 MB 临时缓冲；把文件移出格子不再触发数千次防抖保存。
• 移除剪切大量文件时的卡顿。 此前从格子剪切大块选区时，剪切状态清扫按每个集合事件执行一次，造成可见的列表更新风暴；现在合并为每批一次。
• 为 settings.json 的撤销历史设置上限。 历史此前没有单批上限，反复数千文件的操作会让 settings.json 无限增长（真实档案达到 19.8 MB，放大了每次保存和每次启动）。超出限额的批次保留摘要式历史条目——真实数量、绝不部分撤销——已膨胀的配置在升级后首次启动自动瘦身（19.8 MB 档案迁移后不足 100 KB，24 条历史全部保留）。
• 大批量格子操作更快。 导入与监视器重载改用批内路径索引和二分插入，替代逐文件列表扫描。
• 加固批量事务边界。 恢复日志、撤销回执与放弃标记遵循"检查式持久化"顺序，大批量期间的崩溃或保存失败不会再把已提交的文件恢复回桌面，也不会丢失放弃操作。
