- Starting 2 June 2025 and continuing through the year, IBM Quantum will begin a gradual rollout of new features to [dynamic circuits](/docs/guides/classical-feedforward-and-control-flow) that will enable them at the utility scale.
Improvements include the following:

- A 75x speedup in execution by using the [Gen3 engine stack](/docs/guides/runtime-options-overview#experimental-option-note)
- A 75x speedup in execution by using the Gen3 engine stack

From an archival standpoint, ok to leave the mention of gen3-turbo in the latest-updates page, since they are date-stamped?

It seems more clear to me to remove entirely, given that people may read this and wonder how to use it

Would it help to add a note by any occurrences saying something like "(no longer experimental as of June 2025)" @jyu00 ? I try to resist any appearance of rewriting history.

If so, will do in a followup so that we can get this one merged for now.

I thought the original wording was
... by using the latest (Gen3) engine stack?
If that may still make people wonder about how to use it, then we can say
... by using the latest (Gen3) engine stack, which is the default execution path as of June 2025

Or add a note saying gen3-turbo was removed because it's now the default instead of experimental, as @abbycross suggested.

- Parallel execution of branches, which reduces circuit duration and improves result quality
- Improvement in mid-circuit measurement
- Better integration with dynamical decoupling

- The rollout of the Gen3 engine stack begins today. This engine stack gives a 75x speedup in execution. The rollout will be done on one QPU at a time, where a percentage of the jobs on the QPU will use the Gen3 path. You can also force the Gen3 path using the [`gen3-turbo` experimental option.](/docs/guides/runtime-options-overview#available-options) Note that this engine stack is not compatible with fractional gates, pulse gates, or dynamic circuits.

Setting `gen3-turbo` enables the next-generation execution path, which provides a great improvement in performance. This option is experimental (subject to change without notice, and stability is not guaranteed).
