# @pleach/langchain changelog (/docs/changelog/langchain) This page collects the **site-content changelog entries** that materially touched the [`@pleach/langchain`](/docs/langchain) docs surface or named a `@pleach/langchain` symbol. It is not the runtime changelog — the canonical record of `@pleach/langchain` runtime behavior lives in the upstream package [`CHANGELOG.md`](https://github.com/pleachhq/getpleach) and on [npmjs.org/package/@pleach/langchain](https://www.npmjs.com/package/@pleach/langchain). See the combined site changelog at [`/docs/changelog/combined`](/docs/changelog/combined) for the chronological unified view across every SKU. ## Unreleased [#unreleased] ### Fixed [#fixed] * **Schema `codeRepository` field + GitHub `sameAs` entry added to [`@pleach/langchain`](/docs/langchain)** in the site's Organization + SoftwareApplication JSON-LD `@graph` (inlined in `` on every page). Was the only SKU entry without a `codeRepository` field; its `sameAs` array referenced only the npm page and the docs page. Now declares `https://github.com/pleachhq/langchain`, consistent with the other SKUs. Load-bearing because `sameAs` is the field AI search engines use for entity reconciliation across the npm ↔ GitHub ↔ docs boundary; without the GitHub URL, an AI search asking "where does `@pleach/langchain` live?" had to guess. See the [combined view](/docs/changelog/combined) for the full cross-SKU pack. ## 2026-06-08 [#2026-06-08] ### Changed [#changed] * [Packages](/docs/packages) table corrected to real published version — `@pleach/langchain 0.1.0` (was largely stale "Reserved · placeholder" framing).
