Changelog

All notable changes to the Gymlium Template SDK and developer documentation.

October 2026

Every image a trainer manages now has an optional dark version, stored as <field>_dark and shown in dark mode; the light photo is used in both modes when it is empty. See Dark Mode.
Manifest: added an optional imageSlots array listing your template’s photo spots (slot id, page, section, field, ratio, persona). Signup previews each spot in light and dark, and new sites seed it with a sample photo or the trainer’s own upload. See Manifest.
Validator: checks imageSlots and warns when it is missing. See Validation.
Docs: the manifest reference now matches sdk/template.schema.json: author.id instead of author.email; standard_price, exclusive_price and attribution_removal_price instead of price; preview.thumbnail and preview.screenshots under preview/; the required structure and navZones. compatibility and defaultThemeMode were never read and are gone; trainers pick the default mode themselves. See Manifest.

Released: July 19, 2026

Trainers can now upload an optional favicon during signup and in Dashboard → Appearance.
The platform injects the trainer’s favicon (or the Gymlium default when unset) into every page’s <head> automatically — templates do not render it.
Manifest: added an optional branding.favicon.supported flag. Templates must not ship their own favicon.ico or hard-code a <link rel="icon"> tag. See Manifest and Layout Components.
