The developers of Opera have announced a public release of the Opera browser for Android devices, which has a built-in Ethereum wallet and is “ready for Web 3.0.”

First introduced in July as beta version, the new mobile browser supports not only ETH, but also ERC-20 and ERC-721 tokens, as well as decentralized applications (Dapps), which can be accessed directly from wallet. 

The developers also state that the new product is fully ready for Web 3.0 - the concept of developing Internet technologies, which was formulated by Netscape's head in continuation of the concept of Web 2.0 Tim O’Reilly. Its essence is that Web 2.0 is only a technology platform, while Web 3.0 will allow professionals to create high-quality content and services based on it.

It’s a significant step for one of the world’s leading browsers to add an Ethereum-based crypto wallet and Dapp explorer, and speaks to Opera’s innovative roots and commitment to embracing next generation technology. We see this as an important moment in improving Dapp accessibility, opening Web3 to mainstream audiences, and encouraging developers to build on Ethereum.

The company says it decided to start supporting Ethereum, since this platform has the largest and fastest growing community of developers of decentralized applications.

Access to the Ethereum blockchain will be received through the Infura infrastructure platform, among which ConsenSys is among the investors.

Nuitka 0.6.6 to be Released

This compiler allows to translate a Python script into a C ++ representation, which can then be compiled into an exe file using libpython

Nuitka 0.6.6 has been released. This is a compiler that allows you to translate a Python script into a C ++ representation, which can then be compiled into an executable file using libpython to ensure maximum compatibility with CPython (using regular CPython tools for managing objects) . Fully compatible with current releases of Python 2.x and 3.x. Compared to CPython, compiled scripts show up to 312% higher performance in pystone tests. Project code is distributed under the Apache license.

The new version adds experimental support for Python 3.8 and provides compatibility with libraries and applications sklearn, osgeo, gdal, dill, scikit-image, skimage, weasyprint, dask, pendulum, pytz and pytzdata. Distutils adds support for individual modules (py_modules, not just packages) and packages with separate namespaces. Work with variables in loops has been optimized and optimized options for the abs and all built-in functions have been implemented, as well as accelerated operations with int and long types. Numerous improvements have been made to reduce memory consumption.
In addition, it is possible to postpone the end of support for the Python 2 branch from January to April. In April 2020, the last final update of the Python 2.7 branch will be generated, after which the corrective releases will not be published. At the same time, work on fixing vulnerabilities in Python 2.7 will be continued by community representatives who are interested in continuing to support this branch in their products. For example, Red Hat will continue to maintain packages with Python 2.7 throughout the entire life cycle of RHEL 6 and 7 distributions, and for RHEL 8 it will generate package updates in the Application Stream until June 2024. Recall that the Python 2.7 branch was formed in 2010 and it was originally planned to stop supporting it in 2015, but due to the insufficiently active migration of projects to Python 3, the lifetime of Python 2 was extended to 2020.
