Fixed-Width Layout Snippets for Writing Emails

build Migration considerations

• For a target of Odoo 10.0+: use the `__manifest__.py` manifest name instead of `__openerp__.py`. The filename alone does not establish module age or compatibility. migration-openerp-manifest · source
• snippet — Template 'snippet' uses `t-raw`, deprecated since Odoo 15.0. Prefer `t-out` for escaped output. For intentional HTML, verify sanitization at its source before marking it safe; Markup alone does not sanitize untrusted content. migration-template-t-raw · source

Migration review checklist, not a compatibility verdict. No target version is selected: apply version-specific advice only when migrating to that version or later.
