Release Notes

Version 0.5.1

Fixes

  • Fixed the script getting stuck in an infinite loop when the starting character and the ending character of the query are the same, but they are not quotation marks

Version 0.5.0

Breaking changes

  • Modules structure update. Playwright web drivers are now located in agentql.ext.playwright.sync_api and agentql.ext.playwright.async_api for synchronous and asynchronous versions respectively:
from agentql.ext.playwright.sync_api import PlaywrightWebDriver
from agentql.ext.playwright.async_api import PlaywrightWebDriver

New features

  • Debug Mode

Users can now use AgentQL SDK's Debug Mode to debug their scripts. The following example demonstrates how to enable this mode:

from agentql.sync_api import DebugManager

with DebugManager.debug_mode():
your_script

It will save meta information (like OS, Python version, AgentQL version), logs, error information, last accessibility tree used, and screenshots of every page queried to the debug folder. The default path is $HOME/.agentql/debug.

  • Query Terms' Context

Previously, when describing a term in the query, users would need to do something like this:

{
second_button_from_the_top_next_to_login_button_only_if_hero_image_is_present
}

Now, AgentQL Query supports providing context for the query terms. Add it inside parentheses like this:

{
button(This is the second button from the top. It is next to login button and will only appear when hero image is present)
}

For more details, please check out our query introduction page.

  • Search in Documentation Website

Users can now search for keywords in AgentQL Documentation Website.

Improvements:

  • Added Session#last_query and Session#last_response methods to get the last response and query objects respectively. These can be helpful for debugging purposes.

Version 0.3.0

caution

We've migrated our SDK from webql to agentql to be consistent with our new branding! This release introduces breaking changes. Please refer to "Breaking Changes" section for latest information.

Breaking changes

  • As we have moved our SDK from webql to agentql, our Python library is now called agentql and you can import the same with import agentql

  • API key setup, instead of WEBQL_API_KEY, now the users need to set AGENTQL_API_KEY.

note

We have also updated our docs to reflect those changes! The underlying APIs available and the way they can be leveraged are still the same.

Version 0.2.8

Hotfix release

  • Fixed TypeError: AsyncClient.post() got an unexpected keyword argument 'allow_redirects'

Version 0.2.7

caution

This release introduces some breaking changes. Please refer to "Breaking Changes" section for latest information.

Breaking changes

As we continue drawing a clearer line between Session and WebDriver, we removed several APIs which were previously present in Session class:

# Removed APIs
session.scroll_up()
session.scroll_down()
session.scroll_to_bottom()
session.load_user_session_state()
session.wait_for_page_ready_state()
session.get_user_session_state()
session.save_user_session_state()

All these methods are now available in WebDriver class, so you can use them in the following way:

session.driver.scroll_up()
session.driver.scroll_down()
session.driver.scroll_to_bottom()
session.driver.load_user_session_state()
session.driver.wait_for_page_ready_state()
session.driver.get_user_session_state()
session.driver.save_user_session_state()

Improvements

  • Fixed possible crash in PlaywrightDriver related to unbound variable (#252)
  • Allowed http redirects for AgentQL API calls (#257)
  • Fixed resource leak: reuse existing browser context for iframes (#259)
  • Fixed resource leak: dom update listener is never removed (#258)
  • Moved to tf-playwright-stealth (#260)
  • Relaxed dependency requirements (#261)
  • Added environment variable to control API host (#262)

Version 0.2.6

Improvements

  • Optimized the code by making enable_stealth_mode() method sync in Asynchronous version of SDK.

Version 0.2.5

Highlights

This release introduces public APIs for checking whether web driver is in headless mode and for retrieving web driver instance in Session class. Several bug fixes and code optimization are also included in this release.

New Features

  • API to retrieve web driver instance from Session

Users can now interact with the web driver instance directly from Session class in the following way:

# This will scroll to the bottom of the page
session.driver.scroll_to_bottom()

# This will wait for page to enter a stable state
session.driver.wait_for_page_ready_state()
  • API to retrieve headless setting

Users can now determine whether the browser is started in headless mode by invoking session.driver.is_headless().

Bug Fixes

  • Fixed a bug where users can not chain methods for response object.

Version 0.2.4

Highlights

This release introduces Stealth Mode to SDK. Stealth mode will decrease users' possibility of being marked as bot on some websites.

New Features

  • Stealth Mode

Users can enable stealth mode by invoking enable_stealth_mode() method in Web Driver class. Users can pass in their User Agent, webgl renderer, and webgl vendor information to maximize the effect of stealth mode.

Users can activate the Stealth Mode like this:

import webql as wql
from webql.sync_api.web import PlaywrightWebDriver

driver = PlaywrightWebDriver(headless=False)

# Enable the stealth mode and set the stealth mode configuration
driver.enable_stealth_mode(
webgl_vendor=VENDOR_INFO,
webgl_renderer=RENDERER_INFO,
nav_user_agent=USER_AGENT_INFO,
)

Version 0.2.3

Highlights

This release improves the stability and reliability of SDK by introducing fixes to some known bugs.

Bug Fixes

  • Fixed a bug where page interaction sometimes froze in headless mode.
  • Fixed a bug for data postprocessing in async environment.

Version 0.2.2

Highlights

This release introduces a new API through which users can retrieve Page object from web driver. In addition, this release also includes several bug fixes and code optimization.

New Features

  • New public API for getting Page object from web driver

A public API has been added to Session class for retrieving Page object. With the Page object, users can interact with web pages more freely, such as page refreshing and navigation.

For instance, to refresh the page, users can use the following script:

session = webql.start_session()

# This will reload the current web page
session.current_page.reload()

To navigate to a new website, users can use the following script:

session = webql.start_session()

# This will take the page to a new website
session.current_page.goto("new website link")

Bug Fixes

  • Fixed a bug where None value in response data is not handled properly.
  • Fixed a bug where to_data() method is not working properly in the asynchronous environment.

Version 0.2.1

Highlights

This release introduces a new feature where users can retrieve and load browser's authentication session to maintain login state.

New Features

  • Get & Set User Authentication Session:

With this release, users can maintain the previous login state by initializing a session with the user authentication state.

To retrieve the authentication state from the current session, users can utilize Session class's get_user_auth_state():

# Prior to this point, the script has already signed into a website

# This will retrieve the auth state for current session
user_auth_state = session.get_user_auth_state()

# The session info can be saved to local file system like this
with open(FILE_PATH, "w") as f:
f.write(json.dumps(user_auth_state))

To load the authentication state while initializing the session, users can pass user_auth_state into start_session()'s user_auth_session parameter:

user_auth_session = None

# To load user_auth_session from local file, users can do something like this
with open(FILE_PATH, "r") as f:
user_auth_session = json.loads(f.read())

session = webql.start_session(user_auth_session=user_auth_session)

For a more detailed instruction on how to retrieve and load user session, please refer to the following example in our example repository.

Version 0.2.0

caution

This release introduces some breaking changes. Please refer to "Breaking Changes" section for latest information.

Highlights

This release introduces the asynchronous version of the package. Now users can utilize AgentQL in an optimized fashion within their asynchronous environment.

New Features

  • Asynchronous Support: With this release, users can start an asynchronous session using the following script:
import webql

async_session = await webql.start_async_session()

For a more detailed instruction on how to use async version, please refer to the following example in our example repository.

Breaking Changes

We have introduced some changes to our public API structure. Specifically, users need to choose between synchronous API and asynchronous API when importing web drivers and helper methods.

Now, PlaywrightWebDriver and close_all_popups_handler need to be imported in the following fashion:

  • Synchronous
from webql.sync_api.web import PlaywrightWebDriver
from webql.sync_api import close_all_popups_handler
  • Asynchronous
from webql.async_api.web import PlaywrightWebDriver
from webql.async_api import close_all_popups_handler

The following way of importing PlaywrightWebDriver and close_all_popups_handler is no longer supported.

warning

The following script is deprecated and no longer supported.

from webql.web import PlaywrightWebDriver
from webql import close_all_popups_handler
