Release history

Where a name changed, and when

IPD-IMGT/HLA renames and retires allele names between releases. Translate names typed under one release into another, or see everything that changed between two releases. Answers come from IPD-IMGT/HLA's own name history, every release since 1.05.0.

Translate names between releases

Compare two releases

In your own pipeline

The same answers are in the API: POST /v1/translate, GET /v1/releases/diff and GET /v1/allele/{name}/history, and as the MCP tools translate_names, release_diff and allele_history. See the API reference. Each use here counts as one call of the free daily quota. Only the names you enter are sent; nothing is stored.
