Full Changelog

Changelog

Sourced from scrapy's changelog.

Scrapy 2.19.0 (2026-09-10)

Highlights:

• New RemoteControl extension which allows inspecting and controlling a running crawl over HTTP, used by the :ref:Scrapy MCP server <using-mcp-server>

• Experimental aiohttp-based download handler (now the default when running without a reactor)

Modified requirements

-   Added support for Python 3.15.
    (:gh:`7511`)


New dependencies:


aiohttp_ >= 3.13.3


charset-normalizer_ >= 3.4.0


platformdirs_ >= 2.0.0


(:gh:7866, :gh:8054)


Backward-incompatible changes

• When running :ref:without a Twisted reactor <asyncio-without-reactor>, i.e. with :setting:TWISTED_REACTOR_ENABLED set to False, the default download handler for http and https is now :class:~scrapy.core.downloader.handlers._aiohttp.AiohttpDownloadHandler instead of :class:~scrapy.core.downloader.handlers._httpx.HttpxDownloadHandler. You can configure :class:~scrapy.core.downloader.handlers._httpx.HttpxDownloadHandler in the :setting:DOWNLOAD_HANDLERS setting if you want. (:gh:8118)

• scrapy.http.cookies.WrappedRequest.is_unverifiable() now always returns False, and the undocumented is_unverifiable request meta key that it used to read is ignored. (:gh:7933)
