**Release Date:** January 29, 2026
## Highlights
🎉 **Full MCP 2025-11-25 protocol compliance** with Structured Content (`outputSchema`) for all 150+ tools.
## What's New
### Protocol Compliance
- **Structured Content** — All 150+ tools now include `outputSchema` for type-safe responses
- **Modern Tool Registration** — Migrated to `server.registerTool()` API
- **Progress Notifications** — Long-running admin and backup operations emit progress updates
### New Features

## ⚠️ Breaking Changes
### Security: SQL Injection Remediation
Tools now **reject** inputs containing SQL injection patterns that were previously passed through:
- WHERE clause injection patterns (`;DROP`, `UNION SELECT`, `--`, `/*`, `pg_sleep`)
- FTS config validation (63 chars max, alphanumeric + underscore only)
**Affected tools:** `pg_text_search`, `pg_text_rank`, `pg_trigram_similarity`, `pg_fuzzy_match`, `pg_regexp_match`, `pg_like_search`, `pg_text_headline`, `pg_create_fts_index`, `pg_vector_search`, `pg_vector_aggregate`
## Security
- **CVE-2026-24842** — Docker tar patch upgraded to v7.5.7 (Path Traversal fix)
- **Enhanced Log Sanitization** — Stack flattening, taint-breaking, OAuth field redaction
- **Docker Scout** — 0 fixable critical/high CVEs
