v0.2.6: Dependency Updates & Release Automation

Major Google GenAI SDK update, GitHub Actions modernization, and automated binary releases

We’re pleased to announce Aixgo v0.2.6, a maintenance release focused on dependency updates and release automation. This release brings Aixgo up to date with the latest Google GenAI SDK and modernizes our CI/CD infrastructure.

What’s New

1. Google GenAI SDK Major Update

Updated google.golang.org/genai from v0.5.0 to v1.40.0, bringing significant improvements to the Vertex AI provider:

Breaking API Changes:

The GenAI SDK changed several pointer types to direct values for better type safety:

// Before (v0.5.0)
response.UsageMetadata.PromptTokenCount    // *int32
response.UsageMetadata.CandidatesTokenCount // *int32

// After (v1.40.0)
response.UsageMetadata.PromptTokenCount    // int32
response.UsageMetadata.CandidatesTokenCount // int32

Aixgo’s Vertex AI provider (internal/llm/provider/vertexai.go) has been updated to handle these changes seamlessly.

New Capabilities:

  • Thinking Levels: Enhanced reasoning capabilities for Gemini models
  • Ephemeral Token Support: Improved security for short-lived credentials
  • Multi-Speaker Support: Better context handling for conversational AI

These features are now available to Aixgo applications using the Vertex AI provider with compatible Gemini models.

2. GitHub Actions Modernization

Our CI/CD workflows now use the latest Actions versions with Node.js 24 support:

  • golangci-lint-action: v4 → v9 (improved linting performance and caching)
  • upload-artifact: v5 → v6 (better retention policies and cross-workflow access)
  • download-artifact: v3 → v12 (enhanced artifact management)

These updates improve build reliability and prepare our infrastructure for future GitHub Actions features.

3. Automated Binary Releases

Added .goreleaser.yaml for streamlined release automation using GoReleaser:

Supported Platforms:

# Operating Systems
- Linux (ELF binaries)
- macOS (Darwin)
- Windows (.exe binaries)

# Architectures
- amd64 (x86-64)
- arm64 (Apple Silicon, ARM servers)

CLI Tools Included:

  • orchestrator - Multi-agent system orchestration
  • benchmark - Performance benchmarking suite
  • deploy - Deployment automation
  • tools - Utility commands

Binary Downloads:

Starting with v0.2.6, you can download pre-built binaries from GitHub Releases:

# Example: Download orchestrator for macOS ARM64
curl -LO https://github.com/aixgo-dev/aixgo/releases/download/v0.2.6/orchestrator_darwin_arm64
chmod +x orchestrator_darwin_arm64
./orchestrator_darwin_arm64 --help

4. Installation Documentation Clarity

Updated README with clearer installation paths for different use cases:

For Library Users (embed Aixgo in your application):

go get github.com/aixgo-dev/aixgo@v0.2.6

For CLI Tool Users (use Aixgo commands):

# Option 1: Install via go install
go install github.com/aixgo-dev/aixgo/cmd/orchestrator@v0.2.6

# Option 2: Download pre-built binaries
# Visit: https://github.com/aixgo-dev/aixgo/releases/v0.2.6

For Contributors (develop Aixgo):

git clone https://github.com/aixgo-dev/aixgo.git
cd aixgo
make build

Why This Release Matters

Vertex AI Provider Improvements

The GenAI v1.40.0 update brings production-ready features that enhance Aixgo’s Vertex AI integration:

  1. Thinking Levels: Enable deeper reasoning for complex agent tasks
  2. Better Type Safety: Direct value types reduce nil pointer errors
  3. Future-Proof: Aligns with Google’s long-term AI API design

If you’re using the Vertex AI provider, this update provides immediate access to new Gemini capabilities without code changes.

Release Automation Benefits

GoReleaser integration streamlines our release process:

  • Faster Releases: Automated binary builds reduce release time from hours to minutes
  • Consistent Packaging: All binaries follow the same naming and structure
  • Easy Distribution: Users can choose between go install or pre-built binaries

CI/CD Modernization

GitHub Actions updates improve developer experience:

  • Faster Builds: Improved caching and parallel execution
  • Better Artifacts: Enhanced artifact retention and cross-workflow sharing
  • Node.js 24: Latest runtime for future Actions features

Migration Guide

Upgrading to v0.2.6

For Library Users:

# Update your go.mod
go get -u github.com/aixgo-dev/aixgo@v0.2.6

# Verify dependencies
go mod tidy

For CLI Tool Users:

# Reinstall tools
go install github.com/aixgo-dev/aixgo/cmd/orchestrator@v0.2.6

# Or download new binaries from GitHub Releases

Vertex AI Provider Changes

No code changes required. The provider automatically handles the GenAI SDK updates:

# Your existing configuration works as-is
agents:
  - name: gemini-analyst
    role: react
    model: gemini-2.0-flash-001
    prompt: "Analyze the following data..."
    provider: vertexai

Breaking Changes

None. This is a maintenance release with backward-compatible changes.

What’s Next

The v0.2.6 release sets the foundation for upcoming improvements:

  • Enhanced Vertex AI Features: Leverage thinking levels and multi-speaker support
  • Automated Release Notes: Generate changelogs from commits
  • Binary Checksums: Add SHA256 verification for downloaded binaries
  • Homebrew Formula: macOS package manager integration
