Core Viewpoint - The article discusses a significant update to OpenClaw, focusing on a shift in the plugin ecosystem towards ClawHub as the default entry point, along with major changes in the plugin system and SDK restructuring [2][5]. Group 1: Plugin Ecosystem Changes - The plugin ecosystem is transitioning to prioritize ClawHub for installations, moving away from npm unless a package/version is unavailable on ClawHub [2]. - The plugin system has undergone a major overhaul, including a restructuring of the SDK and a convergence of interfaces [2]. Group 2: SDK and Plugin Development - The SDK path has been restructured to "openclaw/plugin-sdk/*", shifting plugin development from broad interfaces to fine-grained modular SDKs [3]. - The new plugin market includes various tools such as MiniMax M2.7, GPT-5.4-mini/nano, and others, enhancing the capabilities available to users [4]. Group 3: Messaging and Runtime Changes - The messaging mechanism has been rewritten to enforce the use of "describeMessageTool (...)", changing how tools are defined and utilized [5]. - Plugins are now required to use an injected runtime, eliminating the ability to directly call host APIs [5]. Group 4: Core Capabilities and Security Enhancements - Tool capabilities have been consolidated, with built-in abilities replacing third-party skills, exemplified by the unification of image generation capabilities [5]. - Security upgrades in the execution environment include restrictions on JVM injection and control over Gradle environment coverage [5]. Group 5: Model Updates - OpenAI's default model has switched to gpt-5.4, with additional support for gpt-5.4-mini and gpt-5.4-nano, while MiniMax's default model has been updated to M2.7 [5]. - A per-agent model strategy has been introduced, allowing for different reasoning modes for each agent [5]. Group 6: Configuration Changes - The ".moltbot" configuration system has been removed, standardizing environment variables to OPENCLAW_* [5]. - A critical step related to the "Web control UI resources" was missed during the release, but has been addressed in the latest beta version [5][6].
