 # Changelog
 
 ## Unreleased
+- Added `CompactVector::to_bytes` and `from_bytes` for zero-copy serialization.
 - Made `DacsByte` generic over its flag index type with a default of `Rank9SelIndex`.
 - `DacsByte::from_slice` now accepts a generic index type, removing `from_slice_with_index`.
 - Added `BitVectorBuilder` and zero-copy `BitVectorData` backed by `anybytes::View`.

 - Investigate alternative dense-select index strategies to replace removed `DArrayIndex`.
 - Explore additional index implementations leveraging the new generic `DacsByte<I>`.
 - Demonstrate the generic `from_slice` usage in examples and docs.
+- Show `CompactVector::to_bytes` and `from_bytes` in examples.
 
 ## Discovered Issues
 - `katex.html` performs manual string replacements; consider DOM-based manipulation.

 `BitVectorData::to_bytes` and reconstructed using `BitVectorData::from_bytes`,
 allowing zero-copy loading from an mmap or any other source by passing the
 byte region to `Bytes::from_source`.
+`CompactVector` offers similar helpers: `CompactVector::to_bytes` returns a
+metadata struct along with the raw bytes, and `CompactVector::from_bytes`
+reconstructs the vector from that information.
