Release Notes

v1.6.0

•Line Table Engine: new Survey Plat / Line Table mode reads numbered line and curve tables directly and assembles each lot boundary in code, giving more reliable results than drawing-trace mode on surveys with a shared tag table
•Two-step parse: step 1 extracts the full line and curve table, step 2 extracts each tract boundary tag sequence, step 3 assembles and validates in code with no additional API call
•Per-lot acreage validation: stated acreage printed on the plat is captured and carried forward for closure cross-check
•Every line-table-assembled call is flagged for review
•Deed path, Survey Plat / Map mode, chunked parsing, and all exports unchanged

v1.5.1

•Upgraded AI model from Claude Opus 4.8 to Claude Opus 5 (released July 24, 2026)
•Claude Opus 5 delivers significantly improved vision and document analysis
•Prompt caching behavior, token limits, and all parsing logic are unchanged
•Particularly improves plat reading quality on clean, legible survey drawings

v1.5.0

•Survey plat reading: choose Survey Plat / Map on upload to extract metes and bounds directly from a plat drawing, line table, and curve table
•Document type selector added to the Upload tab: switch between Deed / Legal Description and Survey Plat / Map
•Multi-lot plat support: replats that create multiple labeled lots return each lot as its own tract with its own traverse and export
•Division-line and quadrant handling: shared lot lines are traced for both lots and near-cardinal bearings checked against closure to reduce direction errors
•Every plat-derived call is flagged for review as a visual first draft to verify against the source
•Plat parsing pinned to temperature zero for consistent, repeatable output on the same file
•Single-pass parse timeout now scales with page count and file count as well as file size, fixing timeouts on dense multi-page uploads
•Large document time estimate banner aligned with the actual 4-page processing window
•Plat guidance added to upload callout, Help Center, and legal disclaimer

v1.4.0

•Upgraded AI model to Claude Opus 4.8 — improved deed parsing accuracy, more reliable extraction of dense multi-call sentences, and more efficient token usage per parse job
•Multi-tract chunked parsing — deeds exceeding 4 pages now processed in 2-page batches with full tract boundary preservation across batches
•Tract-aware batch merging — each tract in a multi-tract deed maintained as a separate clickable tab in the output grid regardless of page count
•Continuation context — batch 2 and beyond receive the last known tract name and formatting rules to prevent cross-batch call misrouting
•currentTractName tracking — flat-array continuation batches now route calls to the correct tract after a multi-tract batch
•Open traverse support — easement centerlines and right-of-way corridors with a POINT OF TERMINATION no longer trigger the auto-refund; all centerline calls preserved
•Open traverse auto-detection — legacy array format scans raw_text for "point of termination" to identify open traverses without requiring multi-tract object format
•Historical unit conversion rules added to AI prompt — varas, chains, links, rods, and poles now converted to feet with confidence_review flag applied
•Cardinal-only bearing rules — THENCE North / THENCE East and diagonal abbreviations (NWLY, SWLY) now handled with confidence_review flag
•Dense multi-call sentence extraction rule — left-to-right pairing with bearing/distance count verification reduces distance swap errors
•Raw text length tiers — standard deeds cap at 100 characters, large multi-tract or chunked batches cap at 50 characters to protect token budget
•tryParseOrRepair JSON recovery — 4-strategy truncation repair ensures partial Opus responses yield maximum calls rather than a full refund
•Pre-flight document limit enforced before chunked routing — oversized uploads blocked before any credit charge or API call
•AutoCAD DXF export added to Available Downloads on reopened jobs — previously only available immediately after a new parse
•Export GIS, CAD & PDF button — replaces Continue to Export with full-width button matching Quick Draw and Calculate Traverse sizing
•Browser tab title simplified — version number removed, now displays Deed Traverse Pro — {Page Name}
•Token scaling for chunked batches — all batches receive 20k max tokens regardless of page count

•Abuse counter column on Admin page — color coded as counter approaches suspension threshold
