v0.2.0

0.2.0 (2026-10-10)

⚠ BREAKING CHANGES

• format v3 directory records changed in place; v3 images written before this release must be recreated. New names longer than 107 bytes require LONGNAMES (AmigaDOS) or --long-names (FUSE).
• consolidate on-disk format v3 and the write-path performance chain onto main (#83)

Features

• add fault corruption qualification campaign (#70) (37912d9)
• amiga: create, read and follow soft links through dos.library (#85) (8c314b7)
• amiga: mount snapshots as read-only volumes (#72) (3243afb)
• amiga: unify administration commands under bfs (#63) (80b372d)
• aros: build and test BFS natively on AROS x86_64 (#86) (07216b7)
• ci: add reproducible M7 Linux qualification (#58) (cdf477d)

• consolidate on-disk format v3 and the write-path performance chain onto main (#83) (b8ea972)
• fuse: add qualified serialized read-write mount (e6e8f02), closes #41
• unify BFS administration commands (#67) (5b202ff)

Performance Improvements

• consolidate AmigaOS free-tree performance work onto main (#81) (79df2e9)
• speed up metadata listing and drop the handler's protection read on writes (#87) (4ec3d51)

v0.1.4

0.1.4 (2026-09-10)

Features

• add read-only Linux FUSE mount (#53) (9e541e3)
• conformance: add independent host conformance suite (#52) (33eea1d)
• host: add safe portable core lifecycle (#50) (d2343a6), closes #38

v0.1.3

0.1.3 (2026-09-08)

Bug Fixes

• ci: harden release signing with Cosign 3.1.3 (c3277ea)

Maintenance Scope

• Pin Cosign v3.1.3 for signing and release verification, addressing GHSA-fx35-mq7g-6g98 in the release toolchain.
• Refresh the SHA-pinned setup-uv, artifact upload/download and build-provenance actions, and repair Dependabot metadata resolution.
• BFS driver sources and the v2 on-disk format are unchanged from v0.1.2. This release does not add filesystem features or fix the previously observed emulator stalls.
• Release archives include 68020, 68030, 68040, 68060 and 68080 builds; inclusion of a CPU target is not physical-hardware certification.

Qualification Limits

Publication remains gated by the existing emulator smoke tests, archive integrity checks, signatures, provenance verification and public byte-for-byte read-back. Successful qualification runs do not explain or resolve the earlier guest stalls documented in #29.

Physical Apollo 68080 qualification #27, broader fault/corruption qualification #28, and long-duration/resource-pressure testing #29 remain open.

v0.1.2

0.1.2 (2026-09-08)

Bug Fixes

• harden format compatibility and fresh-volume recovery (#31) (4839f78)

Compatibility and recovery

• Reject recognized unsupported format versions and unknown option bits before fallback or writes, with explicit version diagnostics in the handler, bfsformat and bfsfsck.
• Reject volume geometries beyond the v2 block-count range instead of truncating them.
• Initialize both superblock copies with the completed namespace before fresh formatting succeeds.
• The on-disk format remains v2. Future-version recognition requires the documented recognition envelope; this release does not implement a 64-bit on-disk format or migration.

Qualification limits

Successful checks include 271 host tests, 46 Amiga integration checks, and six incompatible-media scenarios, including the exact released binaries. Public archives, signatures and provenance are verified by the release workflow.

The first publication test stalled during exnext_37 and correctly blocked publication. An unchanged full rerun passed, as did two independent local runs of the exact release binaries. The original stall remains unexplained and tracked in #29; the later green run does not resolve it. Physical Apollo 68080 qualification #27, broader fault/corruption qualification #28, and long-duration/resource-pressure testing #29 remain open.

v0.1.1

Superseded by v0.1.2. Update for explicit unsupported-format rejection, checked volume geometry, and complete fresh-format superblock redundancy. See the newer release's qualification limits before use.
