A smaller batch of bugfixes and smaller improvements this month, since the last update was in March. We'll be posting these quarterly from now on, to sync up with our technical leads meetings.

• Use latest SAP fuel figures (Feb 2023)
• Wall elements that have zero for area are marked as 'deleted' for clarity.
• Clarified text on heating page about instantaneous water heating - this toggle is for heating at the point of use, e.g. for electric showers, but users were previously using it for boilers. Hopefully the new text is clearer.
• Solar hot water page cleaned up -most of the time the calculations on the SHW page are excessive, and users often miss filling out the inputs which were lower down the page. We've switch to a layout where only inputs are presented, but you can toggle the display of the full SAP worksheet-like calculations too if that's useful.
• Show more info in the title bar of the browser - previously just said "Home Retrofit Planner", now will include the scenario, project title, etc.
• The commentary page has changed behind-the-scenes in a way we hope will make data loss issues related to this page a thing of the past. Please tell us if you encounter issues with it!
