Right now we have three bugfixes:

• dependent look plugin (changes on how templating works);
• reveal_ansible_type filter plugin and ansible_type test plugin (documentation needs updates, and the type names _AnsibleLazyTemplateDict and _AnsibleLazyTemplateList need special handling in the plugin utils code);
• diy callback plugin (CallbackDIYDict cannot be used; omit is no longer a variable).

Further I had to disable three plugins due to bugs:

• yaml callback: Data Tagging: extending AnsibleDumper can result in strange Python errors ansible/ansible#84781;
• apache2_mod_proxy module: Data Tagging: serialization failure when modules return strings that are objects derived from str ansible/ansible#84797 (has been fixed in ansible/ansible@6567bbd);
• merge_variables lookup: Data Tagging: HostVars.raw_get() is no more ansible/ansible#84799.

Whether the plugins/modules need changes or ansible-core needs fixes depends on the issue, we'll see what happens over time. The YAML callback issue also prevents the sanity tests from passing, since it's currently not possible to even import the YAML callback.
