Full Changelog: v0.9.11...v0.9.12

v0.9.11

Hashline v0.9.11

Bug Fixes

• Fix #106: Translate insert and block anchors through shift table — INS.PRE/INS.POST previously used original line numbers directly as live buffer indices, causing compounding drift in multi-edit patches with inserts at different anchors. Block ops (INS.BLK.PRE/POST, SWAP.BLK, DEL.BLK) had the same defect.

What Changed

• INS.PRE/INS.POST: translate anchor via shift before computing insert position
• INS.POST uses insert_count keyed by original anchor for repeated-at-same-anchor stacking
• Block ops: translate block_start/block_end through shift after resolve_block_span
• DEL.BLK now removes in descending order

Tests

• 4 regression tests covering exact reproduction cases from #106

v0.9.1

Hashline v0.9.1

Bug Fixes

• Fix #104: DEL after bodied SWAP silently deleted wrong lines — the SWAP arm consumed every following Edit::Delete into its removal range, discarding their anchors and applying deletes at the SWAP position instead
• Gate consuming loop on line_num so only deletes from the same parsed op belong to that SWAP

Tests

• 8 regression tests: DEL after SWAP (single/multi-line/range), interleaved SWAPs, two DELs after one SWAP, DEL.BLK after SWAP, stale-hash guard

v0.8.6

Hashline v0.8.6

Bug Fixes

• Accept bare INS <N>: as shorthand for INS.POST <N>: (#92) — previously bare INS was silently ignored, causing patches to only apply the DEL while the insert content was never written
• Replace byte-slicing with UTF-8-safe truncation to prevent panic on multi-byte lines — new truncate_utf8_safe() helper walks back to the last safe char boundary
