Breaking changes

• Before upgrading an eXist 5.2.0 or earlier system to eXist 5.3.0 (or as soon as possible after upgrading), be sure to upgrade existdb-packageservice to the latest release, version 1.3.13 or higher. Since Dashboard relies on this library for all package-related operations, this upgrade must be performed outside Dashboard. To upgrade this package outside of Dashboard, either submit the following query to eXist via eXide or the Java Admin Client as an admin user:

```xquery xquery version "3.1";

repo:remove("http://exist-db.org/apps/existdb-packageservice"), repo:install-and-deploy("http://exist-db.org/apps/existdb-packageservice", "http://exist-db.org/exist/apps/public-repo/find") ```

• The shared resources and markdown packages are no longer bundled with eXist-db. If your application depends on those you can still declare dependencies on them in your package metadata and download them from the package repository.
• eXide’s app generator function has been removed from eXide v3.0.0, as part of important improvements to the application. For generating apps, please use the much better yeoman-based generator-exist tool.
• Dashboard v2.0.8 has a known issue that can cause requests a 404 error to appear after logging in to the administrative section. Until a permanent fix has been discovered, you can clear the affected browser of this problem by logging out and back in via eXide or Monex.
• The default eXist-db configuration settings are not production ready. Make sure to consult our article on best practices before making your eXist-db instance publicly available. The new existdb-config project implements these "best practices" and can easily be used to harden your eXist-db(s) from version 5.1.1 till 5.3.0.
