Upcoming 0.2 release (week of 05/20)

[bracesproul]

We're excited to announce the upcoming release of LangChain 0.2, scheduled for the week of 05/20. This version will remove the dependency of langchain on @langchain/community, a change planned since the 0.1 release to improve our package architecture.

Note: PRs to either langchain or @langchain/community merged into the master branch will not be released until the 0.2 release.

Key points:

• Few breaking changes.
• Extended timeline for some deprecations to allow more time for code updates.

We welcome feedback on the langchain and @langchain/community v0.2 release candidates, as well as on the migration script.

Important notes:

• The main branch now tracks 0.2 progress.
• The v0.1 branch continues to track 0.1 progress.
• We may have 1-2 more releases from v0.1 before the full 0.2 release. For immediate changes and inclusion in 0.2, make PRs against both branches (master and v0.1).

Documentation:

• Current docs are built from the v0.1 branch.
• Preview 0.2 docs (from main) are available here and will soon be linked from a banner on js.langchain.com.
