Browser_ is a web testing library for `Robot Framework`_ that utilizes
the Playwright_ tool internally. Browser library {version} is a new release with
**UPDATE** enhancements and bug fixes.
All issues targeted for Browser library {version.milestone} can be found
from the `issue tracker`_.
For first time installation with pip_, just run
::
   pip install robotframework-browser
   rfbrowser init
to install the latest available release. If you upgrading
from previous release with pip_, run
::
   pip install --upgrade robotframework-browser
   rfbrowser clean-node
   rfbrowser init
Alternatively you can download the source distribution from PyPI_ and
install it manually. Browser library {version} was released on {date}.
Browser supports Python 3.9+, Node 18/20/22 LTS and Robot Framework 5.0+.
Library was tested with Playwright REPLACE_PW_VERSION
