Spring Framework
Ten days after introducing the experimental Spring AI MCP, a Java SDK implementation of the Model Context Protocol (MCP), to the Java community, the Spring AI team has released a version 0.2.0 milestone. This initial release features: a simplified McpClient interface such that listing operations no longer require a cursor parameter; and a new SseServerTransport class, a server-side implementation of the MCP HTTP with the SSE transport specification. Breaking changes include a rename of some modules for improved consistency. Further details on this release may be found in the release notes.
The fifth milestone release of Spring AI 1.0 delivers: incubating support for the Model Context Protocol; support for models such as Zhipuai Embedding-3 and Pixtral; and support for vector stores such as MariaDB and Azure Cosmos DB. There were also breaking changes that include moving the MilvusVectorStore class from the org.springframework.ai.vectorstore package to the org.springframework.ai.vectorstore.milvus package. The Spring AI team plans a sixth milestone release in January 2025 followed by one release candidate before the final GA release.
TornadoVM
The release of TornadoVM 1.0.9 ships with bug fixes and improvements such as: support for the RISC-V 64 CPU port to run OpenCL with vector instructions for the RVV 1.0 board; support for int, double, long and short three-dimensional arrays by creating new matrix classes; and the addition of a helper menu for the tornado launcher script when no arguments are passed. More details on this release may be found in the release notes.
