Sourced from playwright's releases.

v1.60.0

🐍 Python improvements

• New FormData class for building multipart/form-data request bodies — pass to api_request_context.post(form=…) etc.
• expect.soft(...) soft assertions collect multiple failures in a test instead of stopping at the first one. Requires up-to-date pytest integration to work.
• All timeout parameters now accept datetime.timedelta — applies wherever a timeout is taken, e.g. page.goto(), locator.click(), expect(...).to_be_visible().
• Async context manager support across more APIs — async with now works for objects returned from screencast.show_actions(), screencast.show_overlays(), etc.
• page.expect_request(...) and page.expect_response(...) now accept async predicates.
• Typed overloads for expect_event / wait_for_event so the event payload type is inferred per event name.

🌐 HAR recording on Tracing

tracing.start_har() / tracing.stop_har() expose HAR recording as a first-class tracing API, with the same content, mode and url_filter options as record_har:

context.tracing.start_har("trace.har")
page = context.new_page()
page.goto("https://playwright.dev")
context.tracing.stop_har()

🪝 Drop API

New locator.drop() simulates an external drag-and-drop of files or clipboard-like data onto an element. Playwright dispatches dragenter, dragover, and drop with a synthetic DataTransfer in the page context — works cross-browser and is great for testing upload zones:

page.locator("#dropzone").drop(
    files={"name": "note.txt", "mime_type": "text/plain", "buffer": b"hello"},
)
page.locator("#dropzone").drop(
data={
"text/plain": "hello world",
"text/uri-list": "https://example.com",
},
)

🎯 Aria snapshots

• expect(page).to_match_aria_snapshot() now works on a Page, in addition to a Locator — equivalent to asserting against page.locator("body").
• New boxes option on locator.aria_snapshot() / page.aria_snapshot() appends each element's bounding box as [box=x,y,width,height], useful for AI consumption.

New APIs

Browser, Context and Page

• Event browser.on("context") — fired when a new context is created on the browser.
• BrowserContext now mirrors lifecycle events from its pages: browser_context.on("download"), browser_context.on("frameattached"), browser_context.on("framedetached"), browser_context.on("framenavigated"), browser_context.on("pageclose"), browser_context.on("pageload").
