## Unreleased

## 0.4.0 - 2026-07-04

- preserve WKT CRS records during LAS/LAZ-to-COPC conversion and set the LAS
WKT global-encoding bit when a WKT CRS is carried through
- preserve LAS Extra Bytes point payloads and LASF_Spec Extra Bytes descriptor
VLRs through streaming conversion, disk spill, LAZ encoding, and read-back
- pass through source non-CRS VLRs and EVLRs while regenerating COPC info,
LASzip, CRS, hierarchy, and Extra Bytes records in the required output order
- keep streaming conversion out-of-core by carrying Extra Bytes through the
spill file and retaining the temp-file-backed LOD index path
- add release gates for combined CRS, Extra Bytes, VLR, and EVLR round-trips,
plus structural and opt-in large-N bounded-memory writer guards
- reject GeoTIFF-only CRS inputs with a specific unsupported-conversion error
until GeoTIFF-to-WKT conversion is implemented
- breaking: `LasPointRecord` now carries raw `extra_bytes`, and
`StreamingLayout` now carries `extra_bytes` plus Extra Bytes descriptor VLRs

## 0.3.0 - 2026-06-22

- add LAS/COPC-native column types in `copc-core`, materialized column reads in

- Source-trait writer API for caller-owned point storage

- Interior-node representative points for native LOD reads

## Not Yet Supported

- Zero-copy column views directly over compressed COPC/LAZ point data
- Built-in Arrow or DataFusion conversion
- GeoTIFF-only CRS conversion to WKT during LAS/LAZ-to-COPC conversion
