# Mistral Leanstral 1.5 — deprecation status

> No — Leanstral 1.5 is not deprecated as of August 3, 2026. Mistral has announced neither a deprecation nor a shutdown date for it.

Leanstral graduated out of Mistral's labs prefix with this release: the experimental id was labs-leanstral-2603 and it was retired five weeks after 1.5 landed. Losing the labs prefix is the signal that matters here, because ids under it carry no retirement guarantee at all and this one now sits in the supported Apache 2.0 range.
