2025-04-22 Mastra Release

BREAKING CHANGES

CommonJS support in TypeScript for non-bundler environments, enabling easier migration of older projects to Mastra and adds end-to-end tests for these scenarios. #3613

Bundling issues with workspace packages that use native dependencies by detecting such packages among externals, creating tarballs for them, and referencing them locally in package.json to enable proper installation during deployment. #3602

Issues with nested import paths (such as firebase-admin/firestore) by making these imports external when bundling fails. #3452
The bundler to respect the actual NODE_ENV environment variable during development while defaulting to production for standard builds, and adds comprehensive tests to ensure correct environment propagation. #3642
-Server configuration fixes #3669
Mastra server.build configuration options for swaggerUI, openAPIDocs, and apiReqLogs. #3674

The correct log level is used in 'mastra dev' by addressing an environment variable change that caused logs to default to 'WARN' instead of 'INFO'. #3758

Replace __ functions with a Proxy, fixes a potential infinite loop in storage dev.entry, related bug fixes, code refactoring, and test updates. #3665
The Postgres store configuration to use 'schemaName' for consistency with the vector implementation and adds validation to ensure connections are present, throwing an error if not. #3681
Support for Cloudflare D1. #2932
The $in, $nin, and $contains operators for PG and LibSQL to correctly handle arrays and substring matches, aligning their behavior with Mongo and Upstash. #3725

All new messages are saved at least 1ms apart by adjusting createdAt timestamps, adds a function to correct previously misordered tool calls, and includes new tests. #3654
The Memory module's chunkText function to use character-based chunking instead of tiktoken, improving startup performance while maintaining safe chunk sizes. #3627
Message ordering in @mastra/core. #3672
The logic for hiding working memory in messages changed to use a non-mutating update function instead of a mutating one. #3720
A previous change to TokenLimiter caused new messages to be incorrectly inserted into the memory messages array. #3763

Upgraded 'llamaindex' dependencies to newer versions. #3503
Remove LlamaIndex extractors and replace them with custom Mastra extractors. #3647

Fix WebSocket connection issues in OpenAI Realtime #3671
OpenAI realtime tool result. #3680
Voice reference handling and tool-call-start functionality. #3683

External dependencies specified in the telemetry configuration, such as those required by third-party exporters like Langfuse, are properly installed to prevent runner failures. #3762

Add RuntimeContext to AgentNetwork. #3653
Fix table layout issue in the Agent Network section of the Playground, aligning its design with recent updates made to the Agent and Workflow sections. #3744
