# Changelog

This changelog cumulatively lists all public user-facing changes from VeADK 1.0.0 through 1.0.1. Versions are ordered newest first.

## 1.0.1

VeADK 1.0.1 was released on July 7, 2026. It adds Harness, A2A registration, and ADK skill integration, with updates to the Codex runtime and VeADK Frontend.

| Module | Change details | Link |
| - | - | - |
| Codex runtime | Ships sandbox, network, and review defaults that allow full host and network access without interactive approval. | [Runtime safety](/productions/veadk/archives/1.0.1/en/components/agent/runtime#switch-the-execution-backend) |
| Harness | Adds the VeADK Harness extension to prepare context for each turn, compact large tool results, and verify final answers; Harness initialization also applies the agent description. | [Harness plugins](/productions/veadk/archives/1.0.1/en/components/execution-engine/index#use-harness-execution-enhancements) |
| A2A | Adds Harness A2A registration and corrects its registration behavior. | [Remote-agent discovery](/productions/veadk/archives/1.0.1/en/components/execution-engine/index#discover-remote-agents-from-agentkit) |
| A2A | Adds OAuth authentication to A2A calls. | [A2A authentication](/productions/veadk/archives/1.0.1/en/components/security/outbound#a2a-remote-agent-authentication) |
| Codex runtime | Adds configurable retries for transient backend errors and restores web search through the Responses shim. | [Codex backend requests](/productions/veadk/archives/1.0.1/en/components/agent/runtime#codex-backend-requests) |
| Skills | Adds `VeSkillRegistry` for using SkillHub and Skill Space sources with Google ADK `SkillToolset`; local skills should migrate to ADK `SkillToolset`, while the legacy `Agent(skills=..., skills_mode="local")` entry point remains compatible but is deprecated. | [Cloud skills](/productions/veadk/archives/1.0.1/en/components/agent/skills#use-cloud-skills) |
| VeADK Frontend | Adds gateway authentication mode and a missing-Volcengine-credentials notice during agent creation. | [Frontend authentication](/productions/veadk/archives/1.0.1/en/components/frontend/veadk-frontend#authentication) |
| Codex runtime | Passes agent skills through to the Codex runtime. | [Codex skills and tools](/productions/veadk/archives/1.0.1/en/components/agent/runtime#skills-and-tools-in-the-codex-runtime) |
| Codex runtime | Executes an agent's MCP and function tools through the Codex runtime. | [Codex skills and tools](/productions/veadk/archives/1.0.1/en/components/agent/runtime#skills-and-tools-in-the-codex-runtime) |
| Examples | Adds a Codex-runtime example that combines a local skill with an MCP tool. | [Codex skills and tools](/productions/veadk/archives/1.0.1/en/components/agent/runtime#skills-and-tools-in-the-codex-runtime) |
