Models:
Default Context Length: Added helper text in the Add Model wizard showing the resolved default context length per model Model Enforcement: Enforced server-side blocking of disabled models from inference, regardless of client-side reload behavior
Tabnine CLI:
Updated to Tabnine CLI v0.29.2. Tabnine CLI: Upstream Updates Covering Tabnine CLI versions 0.29.1 — 0.29.2 This section gives more detail on upstream updates included in Tabnine CLI versions 0.29.1 and 0.29.2. For clarity, itemized updates have also been noted with the Tabnine CLI version in which they first appeared.
Models:
Availability : Added a dedicated error message for models that become unavailable after a CLI session has already started. (v0.29.1)
Context Window:
Token Limit : Unified the default Tabnine model context limit at 200,000 tokens, updating from 180,000 both the default token limit and the fallback Tabnine model profile context window (v0.29.1)
API error parsing:
Improved Tabnine API error parsing so model_disabled errors are detected before generic 402 or 403 handling. (v0.29.1)
Remote Codebase:
Investigation : Fixed the built-in remote-codebase-investigator subagent so it can actually use Tabnine Context Engine MCP tools. (v0.29.2) Testing : Added a regression test that verifies the remote-codebase-investigator built-in agent declares valid bindable MCP tool names (v0.29.2)
Run Command:
Governance: Fixed organization “Run Command = ask-first” enforcement for known-safe shell commands. (v0.29.2) Sub-Permissions : Added support for organization-level per-command Run Command sub-permissions from the /auth/user governance response. (v0.29.2) Improved Run Command sub-permission matching so command prefixes are matched case-insensitively and more specific prefixes take precedence. (v0.29.2)
Governance:
Parsing : Expanded the Tabnine governance schema to parse both top-level tool settings and Run Command sub-permissions from the backend. (v0.29.2) Policy Behavior: Updated the policy engine and governance manager so admin Run Command rules are ranked and injected correctly. (v0.29.2) Bug Fixes Admin Console / SCIM: Fixed /schemas endpoint not advertising externalId IDE Settings: Fixed documentation link remaining visible and leading to a 404 page when the Documentation feature flag is disabled Run Command: Fixed admin-configured "Auto-approve" exceptions for Run Command prefixes being ignored by the Agent Technical info (plugin versions) for 6.4.3: Engine: 4.339.0 Visual Studio Code & C ursor : 3.361.10 JetBrains IDEs: 1.316.11 Eclipse: 1.188.11 Visual Studio 2022 & 2026: 1.297.11 Tabnine-CLI: 0.29.2 Tabnine Skills: 0.1.4
