What is the biggest new feature in Odoo 19?

The comprehensive AI suite with 14+ modules. It includes AI agents, RAG-based knowledge retrieval, AI-computed fields, AI lead creation, document auto-sorting, call transcription, and website page generation — all powered by LLM integration and pgvector.

Does Odoo 19 require pgvector?

pgvector is required only for AI features. Odoo 19 works without pgvector, but the AI suite will not be available. The ai_auto_install module detects pgvector and automatically enables AI features when present.

What modules were removed in Odoo 19?

Notable removals include account_consolidation (no replacement), sale_ebay, account_predictive_bills (replaced by AI), account_yodlee, account_plaid (use account_online_synchronization), and account_taxcloud (use account_avatax).

Can I upgrade from Odoo 18 to 19?

Yes. Key migration steps include installing pgvector for AI features, updating SEPA references to ISO 20022, reviewing delivery connector changes (REST variants), and planning for account_consolidation replacement if used.
