• Please update all symfony flex recipes, there are 13 pending changes (see https://symfony.com/doc/current/setup/upgrade_major.html#3-updating-recipes)
• For doctrine, there are also major updates (collections: 2.6->3.1, doctrine-bundle: 2.18->3.2, orm: 2.20->3.6, persistence: 3.4->4.2). Did you check those?
• There is the warning message Package doctrine/cache is abandoned, you should avoid using it. No replacement was suggested.. Did you check if doctrine/cache is still needed and if there is a replacement?

For the warning message PearInstaller is not available (removed in Composer 2.x); PearPlugin skipping registration. I opened a ticket in mnsami/composer-custom-directory-installer#52

Please check

• do we have to change the other repositories? PHP version?

• Updated all symfony recipes
• Updated the doctrine/dbal dependency to ensure compatibility with current mapbender requirements

Important:
You must run
bin/console mapbender:database:upgrade
directly after deploying this branch to ensure a successful migration of all database values.
Make a full backup of your database before running the migration command!!

Looks good 👍

Merge this last and change the branch references in mapbender/mapbender and mapbender/digitizer back to develop and composer update once more before merging this.
