- New section [v1.0.0-rc4] - 2026-05-25 with English-language release notes.
- Existing rc1/rc2/rc3 sections translated from pt-BR to technical English

 ## [v1.0.0-rc3] - 2026-05-17
 
-Release de integração — adiciona ferramentas nativas para o LLM agent (Knowledge Nexus search, manage_conversation_labels, link_product_to_pipeline_item), injeção de catálogo de products no contexto do agente, merge das integrações da tabela `agent_integrations` na config do agente em runtime, e correção de bugs em handshake de Postgres e binding do chat handler. Também declara `EXTENSION_POINTS.md` como contrato público de extensão para a Enterprise edition.
+Integration release — adds native tools for the LLM agent (Knowledge Nexus search, manage_conversation_labels, link_product_to_pipeline_item), injection of the products catalog into the agent context, merging of integrations from the `agent_integrations` table into the agent config at runtime, and bug fixes in the Postgres handshake and chat handler binding. Also declares `EXTENSION_POINTS.md` as the public extension contract for the Enterprise edition.
 
 ### Added
 
-- **EXTENSION_POINTS.md (EVO-1376)** (#9) — documento com os pontos de extensão expostos pelo processor para a Enterprise edition. Contrato versionado, sem código novo.
-- **`knowledge_nexus_search` — tool nativa** — agentes ganham acesso a busca semântica em spaces do Nexus diretamente do prompt, sem necessidade de configurar tool customizada.
-- **`manage_conversation_labels` — tool nativa** — list/add/remove de labels na conversa pelo próprio agente.
-- **`link_product_to_pipeline_item` — tool nativa** — agente consegue linkar products do catálogo ao item de pipeline ativo.
-- **Catálogo de products no contexto do agente** — products attachados ao agente são injetados no prompt, permitindo que o LLM tenha contexto da oferta.
-- **Hints de uso de pipeline e labels no prompt** — `pipeline_manipulation` e `manage_labels` ganham hints estruturados no system prompt para orientar o LLM sobre quando e como usar.
+- **EXTENSION_POINTS.md (EVO-1376)** (#9) — document with the extension points exposed by the processor to the Enterprise edition. Versioned contract, no new code.
+- **`knowledge_nexus_search` — native tool** — agents gain access to semantic search on Nexus spaces directly from the prompt, without needing to configure a custom tool.
+- **`manage_conversation_labels` — native tool** — list/add/remove labels on the conversation by the agent itself.
+- **`link_product_to_pipeline_item` — native tool** — the agent can link catalog products to the active pipeline item.
+- **Products catalog in the agent context** — products attached to the agent are injected into the prompt, letting the LLM have context about the offering.
+- **Pipeline and labels usage hints in the prompt** — `pipeline_manipulation` and `manage_labels` gain structured hints in the system prompt to guide the LLM on when and how to use them.
 
 ### Changed
 
-- **`llm-agent` — merge de integrações** — integrações da tabela `agent_integrations` agora são mescladas na config do agente em runtime. Antes a config era estática; agora reflete o estado mais recente das integrações configuradas via UI.
-- **Docs** padronizados para Evolution Foundation 2026 (README, LICENSE, NOTICE, TRADEMARKS).
-- **Docs (org)** — URLs do GitHub atualizadas de `EvolutionAPI` para `evolution-foundation`.
+- **`llm-agent` — integrations merge** — integrations from the `agent_integrations` table are now merged into the agent config at runtime. Previously the config was static; now it reflects the latest state of integrations configured via the UI.
+- **Docs** standardized for Evolution Foundation 2026 (README, LICENSE, NOTICE, TRADEMARKS).
+- **Docs (org)** — GitHub URLs updated from `EvolutionAPI` to `evolution-foundation`.
 
 ### Fixed
 
-- **DB — `sslmode` → `ssl` para asyncpg** — o driver asyncpg não entende `sslmode` (parâmetro psycopg/libpq). Conexões com `sslmode=require` na connection string falhavam silenciosamente; agora traduzimos para o parâmetro nativo do asyncpg.
-- **Chat handler — request param rebind** — corrige binding do parâmetro `request` no chat handler que causava `NameError` em determinados caminhos de erro.
+- **DB — `sslmode` → `ssl` for asyncpg** — the asyncpg driver does not understand `sslmode` (a psycopg/libpq parameter). Connections with `sslmode=require` in the connection string failed silently; we now translate it to the asyncpg native parameter.
+- **Chat handler — request param rebind** — fixes the binding of the `request` parameter in the chat handler that caused `NameError` on certain error paths.
 
 ## [v1.0.0-rc2] - 2026-05-05
 
 ### Fixed
 
-- **Container startup**: invocar `alembic` e `uvicorn` via `python -m` em vez de console scripts, evitando que `sh -c` interprete os entrypoints incorretamente em algumas imagens. (#7)
-- **Migration `26a14ac7025d`**: adicionado `if_not_exists=True` no `op.create_table('evo_agent_processor_execution_metrics')`, tornando a migration segura para re-run em ambientes onde a tabela já foi criada por outro serviço (banco compartilhado). (#7)
+- **Container startup**: invoke `alembic` and `uvicorn` via `python -m` instead of console scripts, preventing `sh -c` from interpreting the entrypoints incorrectly on some images. (#7)
+- **Migration `26a14ac7025d`**: added `if_not_exists=True` on `op.create_table('evo_agent_processor_execution_metrics')`, making the migration safe to re-run in environments where the table has already been created by another service (shared database). (#7)
