Dear May Hallm
Good day!!
I understand your concern but I am sorry to there is no Microsoft KB or blogs to share the details about the bugs and it fixes for SharePoint Online similar to the SharePoint server but you can refer to the Microsoft Roadmap (Microsoft 365 Roadmap - View Latest Updates | Microsoft 365)for checking the upcoming features to the SharePoint Online.
However, all the service incidents related to SharePoint Online can be viewed in the Health section of the Office 365 admin center and changes to the SharePoint Online can be viewed in the message center of the Office 365 admin center.
If you want them to receive the notification to your mailbox or teams, I believe you can use the custom Power Automate flow to meet your requirement. So, I suggest you post your concern in the related community i.e., Microsoft Power Automate Community - Power Platform Community to get the detailed help from the experts.
Apologies for redirecting you to different community as the members in the category posted focus on the users with the Microsoft 365 concern and have limited knowledge on the customization of Power Automate flow, so to get the fast and better assistance, we have redirected you in the correct path.
Thanks for your patience and understanding. Have a good day!!
Best Regards,
Sophia
