Changelog | Obscura Trace

v0.2.1

New icon

Obscura Trace 0.2.1, signed with Developer ID, notarized by Apple and stapled, for macOS 14 or later. Published on October 19, 2026.

Visual fingerprints recognize neither cropping nor rotation.
Batch renaming is only available from the command line, and never on exFAT or FAT32.
A transfer has no pause or cancel; if interrupted, it resumes.
Large collections: measured on 10⁶ real files, analysis memory grows with the size of the collection (analysis peak: 659 MB); a second analysis re-reads files already fingerprinted. Results remain correct.
Apple Silicon: the release suite, Review Center scrolling and hashing throughput are measured there, but not yet the inventory of 10⁵ real files.
High-contrast appearance and large text sizes have not had a manual pass.

v0.2.0

Obscura Trace 0.2.0, signed with Developer ID, notarized by Apple and stapled, for macOS 14 or later. Published on October 9, 2026.

A file the analysis did not see is never reported as gone: files in an unreadable folder, on a disconnected source, or of an unchecked type. The “Résultat” (Result) card names what was not seen.
Photos libraries and application packages are no longer traversed or transferred.
Truncated JPEGs are classified as “Fichiers corrompus” (Corrupted files).
A source can be widened to a folder that contains it, or removed, without losing its inventory or your review decisions.

A source is removed only if it is identical to the copied and verified file; before a permanent deletion, the copy is read back.
The destination is identified by its volume; a missing destination, or one inside the source, is refused.
The confirmation covers the whole plan; failures are named file by file.
The free-space margin is proportional to the transfer: 5%, between 64 MB and 1 GB.
SMB shares measured on a real NAS, three defects fixed. An AFP share cannot be used as a destination.

Only one process writes to a catalog: the command line is refused while the app is open.
A job interrupted by a crash or power loss is flagged “à reprendre” (to resume).
Quitting the app or closing its window during a transfer asks for confirmation.

Visual fingerprints recognize neither cropping nor rotation.
Batch renaming is only available from the command line, and never on exFAT or FAT32.
A transfer has no pause or cancel; if interrupted, it is resumed.
Large collections: measured on 10⁶ real files, memory grows with the size of the collection (analysis peak: 659 MB; reading back a manifest of 10⁶ entries: up to 2.9 GB), and a second analysis re-reads files already fingerprinted. Results remain correct.
Apple Silicon: the release suite, Review Center scrolling, and hashing throughput are measured there, but not yet the inventory of 10⁵ real files.
High-contrast appearance and large text sizes have not had a manual pass.

The full list is in the FAQ, current limitations, and glossary chapter of the guide.
