No end date announced yet . estimated end April 2028

Minimum support period for the UK: the maker promises security updates for products sold in the UK until at least December 31, 2026. This is a legal minimum for that market, not an end date, and it may not apply to other markets.

In the EU the maker lists this model as end-of-life (no date given). That listing is for the EU only.
