Xero Central - Add changelogs to Xero Central Support pages
Things like tax returns change fairly frequently. Not all new features are entirely self-explanatory. Xero Support's Articles are simple and aimed at giving new users basic information, but often lack the detail to be used as an ongoing resource.
I'd suggest adding changelogs to Xero Central Support pages/articles for existing products that have been updated.
For example the IR6 tax return has changed in the 2025 year to match tax law. Estates are still able to use the 33% tax rate in their first 4 years, but the return defaults to the 39% rate.
Existing users will review the Tax tab as the logical first step, then might check the IR6 support page/article. Neither have the answer.
A changelog on the support article would make it easier for users that are familiar with the product to quickly get up to speed with changes.
Product update webinars are fine, but are poor as searchable, permanent resources.
