Web search in apps
Retool added native web search capabilities to the app builder Chat tab and app functions, enabling agent applications to query live web data via a managed Tavily account.
Eval datasets, curated by Bayes from your agents' real conversations
Monte Carlo introduced automated evaluation dataset generation by Bayes, creating Golden and Improvement datasets from an agent's scored conversations across intent and issue clusters.
Pages are generally available
Databricks announced the general availability of Pages in Unity Catalog, providing governed definitions of business concepts organized by domain on the Discover page.
BigQuery project caps are generally available
Project caps, also known as scheduling policies, are now generally available for BigQuery Enterprise and Enterprise Plus editions. This feature allows users to limit maximum slots and concurrency per project within a reservation.
BigQuery reservation assignments support principal routing
BigQuery now allows specifying a principal property on reservation assignments to route queries to specific reservations based on the identity of the user or service account. This feature is generally available for Enterprise and Enterprise Plus editions.
BigQuery JSON_FLATTEN function is generally available
The JSON_FLATTEN function is now generally available. It extracts non-array values from JSON inputs, including those nested within consecutive arrays.

mujoco 4.0.0
MuJoCo 4.0.0 introduces speculative contacts to prevent tunneling of fast-moving objects and adds stateful elasto-plastic deformation for joints, tendons, and flexes. The Python distribution has also been reorganized into separate core, studio, and default packages.
mujoco 3.17.0
Mujoco 3.17.0 introduces a batch API for parallel simulations and adds bending elasticity for 1D flexes using a discrete elastic rod model.
mujoco 3.16.0
Version 3.16.0 (October 14, 2026) Significant new features 1. cf89a6375, 4316935b3, 6d98d9fab, 5f17e92eb, 89d59b11f, 147dc67d0 Frames can now scale their contents at compile time, without modifying the mjSpec, via the new scale, scaling, and massscale attributes.
mujoco 3.15.0
Version 3.15.0 (October 5, 2026) General 1. 1aa68e1ca .mjz archives written on Windows now always use / separators. 2. 1aa68e1ca Assets in a meshdir or texturedir now resolve correctly in .mjz archives when rewritten or when the directory path is absolute, uses .., or uses a URI scheme.

mujoco 3.14.0
Version 3.14.0 (September 22, 2026) General 1. 458189298 Added the ipc flag, an experimental contact mode of the discrete integrator for penetration-free flex contact. Each step minimizes an incremental potential subject to linearized contact constraints, using a barrier-free augmented Lagrangian whose subproblems are the discrete solve.
mujoco 3.13.0
Version 3.13.0 (September 8, 2026) General 1. eb18d77ca The .mjz encoder now writes the root file as model.xml in the archive as this is less susceptible to breakage due to file renaming. 2.
mujoco 3.12.0
Version 3.12.0 (August 20, 2026) General 1. 3f8db4c1 The MJCF grammar is now defined in a single source of truth schema file, src/xml/mjcf.schema. The parser's grammar table, presence constraints, keyword maps, typed attribute bindings and save policies are generated from it and gated by tests, as are the schema's enum keywords and declared defaults against...
mujoco 3.11.0
Version 3.11.0 (July 27, 2026) Engine 1. 4787c809 Added geom/surfacevel: the velocity of a geom's surface as seen by contacts, given as a velocity field with a constant component and a rotational component about the geom frame origin.
