Changes

  • composer.json: raise elasticsearch/elasticsearch from ^8.0 to ^8.12 — the PHP client is released per minor only (there is no 8.12.2 client tag; ^8.12.2 would skip the 8.12 client entirely and make 8.13 the effective minimum, which officially does not support an 8.12 server).
  • Docs: document Elasticsearch server >= 8.12.2 as the minimum supported version (upgrade notes + README), bump the docker example to elasticsearch:8.12.2.

Why

Chunking / nested vector support requires Elasticsearch server >= 8.12.2.
Ref: https://github.com/pimcore/internal-improvements/issues/25 (part of pimcore/product-management#1322)

Merge order

Merge this before the companion PRs, which raise pimcore/elasticsearch-client to ^2026.3:

  • pimcore/generic-data-index-bundle
  • pimcore/data-hub-simple-rest

🤖 Generated with Claude Code

Require elasticsearch/elasticsearch ^8.12 so the installed client is the
one paired with Elasticsearch server 8.12.x. Server 8.12.2 or higher is
the new minimum supported version (needed for chunked/nested vector
support, see pimcore/internal-improvements#25).
