The link on this page for FW:
https://www.fractalaudio.com/axe-fx-iii-downloads/
Is always going to be considered a stable release.
The Betas are just that, experimental changes that are likely to not be 100% stable.
Official FW releases here on the forum are not considered final/stable but are no longer Betas.
The release listed at
https://www.fractalaudio.com/axe-fx-iii-downloads/ will always be a stable release where all known bugs have been worked out. FW 24.03 SHOULD be showing up in your Fractal Bot. If it is not, ensure you have the latest Fractal Bot and Axe Edit. If that still does not work there are workarounds to install, but the way it is programmed it should be telling you if a new FW release is available (although it does not recognize the Beta's as new releases and will not warn you from what I understand).
We need to understand that when developing anything, there are going to be delays before one can truly declare something "stable". In order for that to happen, the FW (including FW's that have graduated from beta) must be in circulation to reach such a conclusion. Therefore, when a FW is released and is NOT a Beta, it will not be instantly put on the downloads page of the FAS website as that slot has been reserved for something that has reached all above criteria. It will be put on that page once it has spent some time in the field to ensure that all bugs have been found and addressed. On the forum, we are LUCKY to be able to enjoy the incremental updates, even prior to them meeting all criteria to be considered stable.
If you choose to use the FW's from here on the forum pages as opposed to the FW appearing at
https://www.fractalaudio.com/axe-fx-iii-downloads/, you are doing so at your own risk. If you have any concerns, use ONLY the FW that is listed on the
official stable release page. Otherwise, be prepared to be both a guinea pig and a leech ;~))
