Notable Changes

Non-blocking / reactive support by @dliubarskyi in #5527

An AI Service method used to hold its thread for the whole interaction - the model call, tool execution, memory I/O and guardrails. It can now return CompletableFuture<T>/CompletionStage<T> for a single response, or Flow.Publisher<AiServiceStreamingEvent>/Flow.Publisher<String> for streaming, and the interaction runs without blocking a thread. You choose the mode by the method's return type; nothing else about the interface changes.

Non-blocking goes all the way down, because a blocking gap at any layer re-blocks the whole call: tool calling (sync and CompletableFuture tools, sequential or concurrent), chat memory, guardrails, and the full retrieval graph including EmbeddingModel, EmbeddingStore, ScoringModel and WebSearchEngine.

The work is additive and marked @Experimental: the synchronous and TokenStream APIs are untouched. A few defaults deliberately differ on the async path - multiple tool calls run concurrently, a tool execution error fails the invocation rather than being sent to the LLM, and a tool argument-parse error is sent to the LLM rather than failing. See Non-blocking and Reactive.

Jackson 3 opt-in support by @dliubarskyi in #6184

Add langchain4j-jackson3 to your classpath and LangChain4j's JSON runs on Jackson 3. There is nothing to configure and no API to call, and removing the dependency puts everything back on Jackson 2. Nothing changes for anyone who does not opt in.

With the opt-in in place, Jackson 2 can be excluded outright from most of the dependency graph; the modules that still need it are listed in the documentation. The one deliberate behaviour change is that a JSON failure surfaces as JsonReadException or JsonWriteException (both LangChain4jException) instead of a RuntimeException wrapping Jackson's own - catching RuntimeException works either way. See Using Jackson 3.

What's Changed

1.19.1 MCP backports by @jmartisk in #6329

Full Changelog: langchain4j/langchain4j@1.19.0...1.19.2

`v1.19.1`: and 1.19.1-beta29: published in error, do not use

Compare Source

[!WARNING]
This release was published by mistake. Do not use it.

It was cut from main instead of release/1.19.x. Despite the version number, it is not a patch on top of 1.19.0: it contains all of 1.20.0 plus three commits that landed after it — 108 commits and 300 files ahead of 1.19.0.

Maven Central is immutable, so these artifacts cannot be withdrawn. This note is the only way we can flag them.

Which version should I use?

If you are on	Use	Why
`1.19.0` or earlier, and want to stay on the `1.19.x` line	`1.19.2`	The intended patch: `1.19.0` + the MCP backports
`1.19.1`	`1.20.0` or later	See the warning below
anything else	`1.20.0`	Current release

[!CAUTION]
If you are already on 1.19.1, do not "upgrade" to 1.19.2.
1.19.2 is numerically higher but contains less code — it is the real 1.19.0 + backports, while 1.19.1 accidentally shipped everything up to and beyond 1.20.0. Moving 1.19.1 → 1.19.2 would silently remove ~108 commits of functionality from your build. Go to 1.20.0 or later instead.

What replaced it

1.19.2 / 1.19.2-beta29 is the patch that 1.19.1 was meant to be: 1.19.0 plus the MCP backports from #6329, and nothing else.

Also affected

langchain4j-spring 1.19.1-beta29 was published from the same faulty run and carries the same warning. Use 1.19.2-beta29 or 1.20.0-beta30.

Note for anyone comparing APIs

Because 1.19.1 sits between 1.19.0 and 1.20.0 in version order while containing post-1.20.0 code, tools that pick "the newest release below X" as a baseline (revapi's oldVersion=RELEASE, among others) will select it and report misleading API differences for any 1.19.x build.
