Cline v3.86.0 Adds Claude Opus 4.8 and Moonshot Kimi K2.6 Support

Cline, the AI coding assistant VS Code extension, released v3.86.0 on May 28, 2025, adding support for two new model providers.

New Model Support

The release adds provider integration for Claude Opus 4.8, including 1M-context variants where available. This follows Anthropic's recent release of the Claude 4 series, bringing extended context capabilities to the Cline coding workflow.

Cline also now supports Moonshot AI's Kimi K2.6 model, expanding its range of available LLM backends beyond the existing OpenAI, Anthropic, and other providers.

Technical Fixes

The update resolves a display issue where prompt-cache support for Qwen 3.7 Max was not properly shown in the Cline provider interface. The prompt caching feature allows for more efficient API usage by reusing previously processed context.

Additionally, v3.86.0 fixes startup permissions in the VS Code nightly publish workflow, addressing a deployment pipeline issue.

Project Restructuring

The development team moved the VS Code extension project into a new apps/vscode directory structure, indicating a shift toward a monorepo organization. This architectural change typically enables better code sharing and development tooling across multiple application targets.

What This Means

Cline's rapid integration of Claude Opus 4.8 — within days of its release — demonstrates the competitive pressure among AI coding assistants to support the latest models. The 1M-context support is particularly relevant for developers working with large codebases who need the assistant to understand extensive file hierarchies and dependencies. The addition of Moonshot Kimi K2.6 continues Cline's strategy of provider diversity, giving users options beyond the dominant OpenAI and Anthropic ecosystems, which may offer cost or performance advantages for specific use cases.
