No it hasn't, you don't sit on 60%-enriched Uranium for 3 years (they announced it back in 2022!) if you plan to make a bomb.

IAEA also confirmed that Iran didn't have ongoing military nuclear project.

The reason why they raised their enrichment level was to raise their bargaining power to force the US to come back to the negotiation table in an attempt to get rid of the sanctions.

They almost succeeded since US and Iran were supposed to meet last Sunday, but that was not taking Israel into account, which killed the chief negotiator and convinced Trump to bomb Iran just 3 days in the “two weeks” negotiation deadline he had set earlier this week.
