Full Release Notes

## Highlights

**ECC Tools Pro is live.** The GitHub App now has Stripe billing with a Pro tier ($19/seat/month) for private repo analysis, 50 analyses/month, and AgentShield-backed scanning. Free tier remains at 10 analyses/month for public repos. Install at [github.com/apps/ecc-tools](https://github.com/apps/ecc-tools), upgrade at [ecc.tools/pricing](https://ecc.tools/pricing).

**Selective install is here.** Install only what you need with `--with` and `--without` flags. `ecc install --profile developer --with lang:typescript --with agent:security-reviewer --without skill:continuous-learning`. Agent and skill component families are now in the install manifest.

**12 language ecosystems.** C#, Rust, Java, Kotlin, C++, Go, Python, TypeScript, Perl, PyTorch, Nuxt 4, and Flutter now have dedicated rules, agents, or skills.

**AgentShield v1.4.0 ships alongside.** False positive scanning fixed. CVE database with 25+ known MCP vulnerabilities. Supply chain verification. Runtime monitoring. Watch mode. PR security gate. Org-wide policy enforcement.
