# April 2026 release notes

> April 2026 updates and improvements to Octoparse integrations.

<Update label="April 24, 2026" description="Weekly update" tags={["MCP Server"]}>
  ## New features

  * **Dual-mode `execute_task`** — The [`execute_task`](/en/mcp/execute-task) tool now automatically picks the best execution path for your client. Clients that support MCP Task receive real-time progress updates and streamed results as the run progresses. Other clients get a task ID immediately and can poll for results, so long-running scrapes no longer block the session.
  * **API key authentication** — You can now connect to the [Octoparse MCP Server](/en/mcp) using an API key in addition to OAuth. API keys make setup easier in headless or automated environments such as Claude Code, VS Code, TRAE, and OpenClaw. Generate a key from the [Octoparse account center](https://www.octoparse.com/console/account-center/api-keys).

  ## Updates

  * **Free trial credits for MCP** — Free and Basic accounts now receive **2,000 records per week** for MCP extraction, with no upgrade required to get started. See [Prerequisites](/en/mcp#prerequisites).
  * **Gemini support** — Gemini is now a fully supported client for the MCP Server. See the [setup guide](/en/mcp#supported-clients).
</Update>

<Update label="April 3, 2026" description="Weekly update" tags={["CLI"]}>
  ## New features

  * **`octoparse detect`** — New command that opens the Octoparse extension browser, inspects a URL, and generates a local task file. Supports `--auto` for automatic region selection, `--manual` for guided browser interaction, and `--agent` / prepare-preview-apply for AI agent workflows. See [Create tasks from a URL](/en/cli/guides/detect).
  * **OAuth login** — `octoparse auth login --oauth` opens a browser-based OAuth flow and stores access and refresh tokens locally. Useful when you prefer not to manage API keys manually.
  * **`auth info` command** — New `octoparse auth info` subcommand shows detailed account and credential information for the active session.
  * **`OCTO_ENGINE_ACCESS_TOKEN`** — New environment variable for bearer token authentication. Useful in short-lived CI jobs where storing credentials is not desirable.

  ## Updates

  * **JSONL event types expanded** — `run --jsonl` now emits `captcha`, `proxy`, `download.started`, `download.succeeded`, and `download.failed` events in addition to the previous set. See [Output and exit codes](/en/cli/reference/output-and-exit-codes).
  * **`--lot-id` flag for export** — `data export` and `local export` now support `--lot-id <lotId>` to export a specific run lot rather than the latest.
  * **`--chrome-path` for diagnostics** — `doctor` and `browser doctor` now accept `--chrome-path` to test a specific Chrome installation.
  * **Linux arm64 clarified** — Local extraction (`run`, `detect`) is not supported on Linux arm64 because Chrome for Testing has no Linux arm64 package. Cloud extraction works on all platforms.
