Eino: v0.1.*-first release

v0.1.6

Release date: 2024-11-04

Features

• NewTool, InferTool generic parameters now support struct
• Deprecated WithGraphRunOption(), added new WithRuntimeMaxSteps method
• Adjusted ToolsNode NodeName, added TooCallbackInput/Output struct
• Added MultiQuery, Router two types of Retriever in Flow
• Added document.Loader, document.Transformer two component abstractions
• Added file_url, audio_url, video_url three types to Message MultiPart

BugFix

• Error handling when InputKey does not exist in the map for nodes with InputKey
• Adjusted Name, Type, ID combination method when merging Message Stream (ConcatMessage)

v0.1.5

Release date: 2024-10-25

Features

• When ConcatMessages, validate whether nil chunks exist in the Message stream, throw error if they do, preventing stream producers from inserting nil messages
• Added Type field in Message.ToolCall to represent ToolType, and added incremental merging of ToolType in ConcatMessages

v0.1.4

Release date: 2024-10-23

Features

• Adjusted Chain implementation, wrapped Chain based on Graph[I, O]
• When upstream output node is an interface and downstream input node is an implementation of that interface, support attempting to assert upstream output interface as downstream input instance.
  • For example, now supports scenarios like: Node1[string, any] -> Node2[string, int]. In such scenarios, it previously threw an error at Compile time, now it attempts to assert any as string, and if assertion succeeds, continues execution.
• Added Type field to schema.Message

BugFix

• Corrected Eino Callback RunInfo information during Tool execution
  • Corrected RunInfo Component and Type fields
  • ToolName used as RunInfo.Name
• Passthrough node now allows setting OutputKey

v0.1.3

Release date: 2024-10-17

BugFix

• Fixed ToolsNode returning Message with extra ToolCalls causing model errors
  • This issue was introduced in v0.1.1’s react agent support for tool return directly, which extended ToolsNode returned information. This patch uses a different approach to implement tool return directly, avoiding this issue.

v0.1.2

Release date: 2024-10-14

Features

• StreamReader.Copy() method re-optimized to Goroutine Free Copy method. Prevents Goroutine leaks when business forgets to call StreamReader.Close()
• Validation check: Passthrough nodes do not allow adding InputKey/OutputKey
• Compile Callback Option now supports InputKey, OutputKey passback

v0.1.1

Release date: 2024-10-14

Features

• React Agent supports static configuration of Tool ReturnDirectly

BugFix

• Reverted new Stream Copy logic.
  • Due to implementing Goroutine Free Stream Copy, Recv could potentially hang. Expected to fix in next Patch

v0.1.0

Release date: 2024-10-12

Features

• Support for ChatTemplate/ChatModel/Tool/LoaderAndSplitter/Indexer/Retriever/Embedding multiple component abstractions and implementations
• Support for Graph/Chain/StateGraph and other orchestration tools
• Based on whether input and output are streaming, supports 4 interaction modes with built-in Stream tools
• Flexible and extensible aspect design
