AI Summary

RVF v0.3.4 introduces durable copy-on-write (COW) branches and resolves correctness issues related to immediate read-through for sparse vector IDs. The release includes security hardening measures such as overflow checks and allocation caps to prevent abuse.

Key Highlights

Implementation of durable COW branches that survive reopen and relocation
Correction of immediate read-through for one-based and sparse vector IDs
Security enhancement: membership capacity derived from highest ID with overflow checks
Security enhancement: dense membership allocation capped at 64 MiB
Improved branch lineage and ID map persistence across sessions

Breaking Changes

Affected npm releases are deprecated with upgrade guidance

New Features

Queryable, durable RVF copy-on-write branches
Corrected immediate read-through for sparse vector IDs

Full Release Notes

## Durable COW branches and sparse-ID correctness

This release completes queryable, durable RVF copy-on-write branches and corrects immediate read-through for one-based and sparse vector IDs.

### Published packages

- crates.io: `rvf-runtime` 0.3.2
- npm: `@ruvector/rvf` 0.3.4
- npm: `@ruvector/rvf-node` 0.2.3
- npm: all five `@ruvector/rvf-node-<platform>` packages at 0.2.2

### Security and correctness

- membership capacity is derived from the highest vector ID, with checked overflow
- dense membership allocation is capped at 64 MiB to fail closed against allocation abuse
- branch lineage, edits, tombstones, ID maps, and relative parent references survive reopen and relocation
- affected npm releases are deprecated with upgrade guidance

### Validation

- 14/14 COW integration tests and 9/9 membership tests
- five-platform native build matrix
- clippy with warnings denied, formatting, lockfile integrity, dependency review, cargo-deny, RustSec, and npm audit
- clean-registry native and SDK immediate/reopen COW smoke tests

Merged in #740 and #741.
