This is the first of what will hopefully be weekly updates. First of all I am now working full time on Intervals.icu so expect a lot more functionality in future!

My focus this week has been on improving performance and scalability of the platform. Intervals.icu now has a new binary protocol that reduces the amount of data that needs to be sent from the server to the browser, greatly improving performance. If you would like to help test this have a look at [this forum post](https://forum.intervals.icu/t/activity-fetch-performance-improvement/75457).

The new protocol will be enabled for everyone after some more testing (and bug fixes).

Other changes:

- Added app version number on the /settings page near the bottom. Intervals.icu should update automatically but this is under the control of the browser and doesn’t always work. If you don’t see at least “Version 2024-09-13 07:16:26” then reload the page and check that it updates
- Replaced the left/right power balance chart on the activity power page with a much better contour plot. You can build your own similar plots with [no programming needed](https://forum.intervals.icu/t/custom-activity-heatmaps/74770)
- FIT file record field ‘power’ favoured when there are multiple power fields
- Added power field to activity fields available on the activity list view
- Added gear and description to activity CSV
- Added custom activity fields to activity CSV
- Added Core’s heat strain index trace (note that this will only work in future, when Core have released new firmware)
- Added activity week number link to columns for the activity list view (goes to that week on the calendar) and deep linking to calendar and list
- Fixed a number of internationalisation issues (missed translations etc.)
- The list activities API endpoint now uses 23:59:59 for time if newest is only a date (was 00:00:00)
- Fixed bug with pace zones copied from other athletes not working
- Fixed home menu option sometimes failing on non-inverted calendar when navigating from an activity
