+# Browser library 19.12.6
+
+
+[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 19.12.6 is a new hotfix release with fixes to supporting large responses
+from NodeJS side to Python side, timeout argument was added to gRPC messaging when
+browser and context was closed, @yao-pkg/pkg reference was fixed and run on failure
+was not always called when keyword failed. There are also formatting changes
+to NodeJS side, caused by using the Eslint latest major release and fixing the
+linting errors (which should not affect users of the library.) All issues targeted
+for Browser library v19.12.6 can be found from the
+[issue tracker](https://github.com/MarketSquare/robotframework-browser/issues?q=state%3Aclosed%20milestone%3Av19.12.6).

+## Acknowledgements
+
+### grpc message size limits causes keyword failures with large DOMs ([#4391](https://github.com/MarketSquare/robotframework-browser/issues/4391))
+Keywords could fail, if returned message exceeded the default gRPC maximum message
+size. This is now avoided by making messaging using a streaming API in gRPC
+messaging in several places in the library. Many thanks for Frank Stenzhorn
+for reporting the problem and tonyr-qf for providing a PR to fix the problem.
+
+### Get Attribute should take page screenshot when test failure when either selector or attribute is fail ([#4711](https://github.com/MarketSquare/robotframework-browser/issues/4711))
+if keywords failed in AttributeError, it did not execute the run on failure
+functionality. This is now fixed and run on failure is executed also with
+AttributeError error raised. Many thanks for SiongWaiVidispine to reporting
+the problem and providing a PR to fix it.
+
+## avoid github references in package.json ([#4735](https://github.com/MarketSquare/robotframework-browser/issues/4735))
+@yao-pkg/pkg reference pointed to GitHub release and not a release in the NPM
+side. This is now fixed.
+
+## Eternal freeze when calling Close Browser keyword on robotframework-browser ([#4124](https://github.com/MarketSquare/robotframework-browser/issues/4124))
+If Browser library was used with pabot, in some cases it could lead in
+freeze when browser or context was closed. This is now fixed by adding
+timeout argument in gRPC messages.
