+# Browser library 19.13.0
+
+
+[Browser](https://github.com/MarketSquare/robotframework-browser) is a web testing
+library for [Robot Framework](http://robotframework.org) that utilizes the
+[Playwright](https://github.com/microsoft/playwright) tool internally. Browser
+library 19.13.0 is a new release with new keyword to control presenter mode and changes
+to internal dependencies. This release enables creation of unit test in NodeJSside and
+changes NodeJS grpc protobuf creation. Both of these changes should not affect user,
+but there was quite a lot of changes, so lets be careful out there.
+All issues targeted for Browser library v19.13.0 can be found from the
+[issue tracker](https://github.com/MarketSquare/robotframework-browser/issues?q=state%3Aclosed%20milestone%3Av19.13.0).
+For first time installation with [pip](https://pip.pypa.io/en/stable/) and
+[BrowserBatteries](https://pypi.org/project/robotframework-browser-batteries/)
+just run
+```bash
+   pip install robotframework-browser robotframework-browser-batteries
+   rfbrowser install
+```
+to install the latest available release. If you upgrading
+from previous release with [pip](http://pip-installer.org), run
+```bash
+   pip install --upgrade robotframework-browser robotframework-browser-batteries
+   rfbrowser clean-node
+   rfbrowser install
+```
+For first time installation with [pip](http://pip-installer.org) with Browser
+library only, just run
+```bash
+   pip install robotframework-browser
+   rfbrowser init
+```
+If you upgrading from previous release with [pip](http://pip-installer.org), run
+```bash
+   pip install --upgrade robotframework-browser
+   rfbrowser clean-node
+   rfbrowser init
+```
+Alternatively you can download the source distribution from
+[PyPI](https://pypi.org/project/robotframework-browser/) and
+install it manually. Browser library 19.13.0 was released on Wednesday April 1, 2026.
+Browser supports Python 3.10+, Node 20/22/24 LTS and Robot Framework 6.1+.
+Library was tested with Playwright 1.59.0

+## Most important enhancements
+
+**EXPLAIN** or remove these.
+
+### Create unit test and coverage for NodeJS side ([#4767](https://github.com/MarketSquare/robotframework-browser/issues/4767))
+Now, finaly Iwould say, it is possible to create unit test to the NodeJS side
+of the library. Also we support collecting coverage from the NodeJS side. Coverage
+collection needed small, controlled by an environment variable:
+ROBOT_FRAMEWORK_BROWSER_NODE_COVERAGE, code change. If users do not have that
+environment variable set, this change should not affect users.
+
+### grpc_tools_node_protoc_ts is having security issues ([#4778](https://github.com/MarketSquare/robotframework-browser/issues/4778))
+The grpc_tools_node_protoc_ts was not updated for few years and it started to
+accumulate security issues. Therefore we changed this dependency to ts-proto. Also
+we switched google-protobuf to @bufbuild/protobuf in runtime dependencies.
+
+This change required quite a big refactoring in the NodeJS side, because
+grpc_tools_node_protoc_ts did sit pretty central place in out architecture. Although
+this change should be in theory invisible for the users, there was quite a lot of
+changes. I know that our test coverage is not bullet proof, so this change can cause
+unseen problems. So be careful out there and report any problems.
+
+## Acknowledgements
+
+## Feature request: Ability to enable/disable presenter mode during test execution ([#4772](https://github.com/MarketSquare/robotframework-browser/issues/4772))
+Many thanks to Marko Rautiainen to suggesting and implement a keyword which
+allows to control presented mode during test execution. In previous version
+it was only possible to control it in the library import.
