We're excited to announce the release of ArcadeDB 25.3.1, bringing significant storage improvements, performance optimizations, and several new features while maintaining full compatibility with previous database formats.

Major Enhancements

🔄 Complete Space Reuse and RID Recycling

With this release, ArcadeDB now fully reuses space from deleted records and recycles Record IDs (RIDs), significantly improving storage efficiency and reducing database growth over time. This optimization is particularly valuable for applications with high record turnover.

⚡ Performance Improvements

The storage engine now prioritizes using the first available space instead of searching for the best-fit option, resulting in faster write operations without compromising storage efficiency.

New Features

💻 Enhanced Database Management

The new SQL command check database compress provides a convenient way to optimize database storage
Improved date/datetime handling with modern Java classes
Initial Helm chart implementation for streamlined Kubernetes deployment

🐍 Expanded Testing Infrastructure

Dedicated Python module for testing
End-to-end Python tests integrated into CI workflow

🔧 PostgreSQL Compatibility Enhancements

PostgresType now supports array types, improving compatibility with PostgreSQL clients

Bug Fixes

Resolved Date storage issues
Fixed triple quote handling in Cypher strings
Several test identity updates
