Release Notes - v1.0.0 Release Candidate
This release candidate for v1.0.0 introduces Lambda Managed Instances, multi-tenancy support, and includes stability improvements in preparation for general availability.
Lambda Managed Instances
Lambda Managed Instances provide enhanced control over Lambda execution environments:
- Automated provisioning and scaling of Lambda execution environments
- Reduced cold start latency through optimized instance warm-up and reuse
- Optimized instance allocation to reduce execution costs
This feature enables developers to build more performant serverless applications while maintaining Lambda's scalability model.
Multi-Tenancy Support
This release includes multi-tenancy capabilities for secure isolation and resource management:
- Data, compute, and configuration isolation across tenants
- Centralized monitoring and management dashboard
- Enhanced access controls and audit logging
These capabilities support building SaaS applications with strong isolation guarantees.
Release Candidate Status
This v1.0.0 release candidate includes:
- All planned features for v1.0.0 implemented and tested
- Comprehensive unit, integration, and performance testing
- Complete documentation including user guides and API references
- Focus on bug fixes and stability improvements
Additional Updates
- Performance optimizations across core components
- Improved error handling and diagnostic messaging
- Updated dependencies and security patches
- Enhanced tooling integration
Feedback
Report issues or provide feedback through standard channels during the release candidate period.
Next Steps
The v1.0.0 GA release is planned following the RC period and incorporation of community feedback.
