JetBrains will host a livestream on November 18 from 4:00 to 5:00 pm CET featuring Viktor Kiselev and Guillaume Garnier from its Air product team, focused on scaling agentic AI development through Air Governance. The session will cover centralized management of developer access to AI agents such as Claude Agent, Codex, and Junie, including policy configuration, spending limits, and analytics for usage, impact, and cost. Attendees will also see how governance settings apply across JetBrains IDEs, the CLI, and Air on the web, receive practical rollout guidance, and have an opportunity to ask questions during a live Q&A.

JetBrains has released bug-fix updates for MPS 2026.2 RC2, 2026.1.2, 2025.3.3, 2025.2.5, and 2025.1.5 to address a critical security issue related to compromised eMudhra certificates. Users of MPS 2025.1.5 and 2025.2.5 must also disable JCEF through the ide.browser.jcef.enabled Registry flag, while developers distributing MPS-based RCP applications should take additional security measures because JBR and JCEF are affected. MPS 2026.1.2 and 2026.2 RC2 additionally include planned Projectional Agent Toolkit enhancements, such as a consolidated MCP tool API, performance improvements, type-system tools, quick-fixes, log access, project management capabilities, automatic skill database updates, and corrections for SModel expressions in parsed Java statements. The older 2025 releases contain only the security fix, and users are advised to consult the related security announcement and update their MPS installations.
