IntelliJ IDEA 2021.3 offers numerous valuable updates! You can use the remote development (Beta) feature to connect to a remote machine, deploy an IDE backend on it, and work on a project located there as if it were on your local machine. In version 2021.3 we’ve also introduced the Repair IDE action – a new way to troubleshoot IDE problems – as well as debugger updates, the Constant conditions inspection for Kotlin, and many other improvements.

WebStorm 2021.3 is packed with many improvements, such as support for ES2022’s private class members, new features for remote development, better support for monorepos and the Deno LSP, the ability to split the Run tool window, and more.

PyCharm 2021.3 brings support for Poetry, a popular dependency management and packaging tool; FastAPI, a hot web framework for building APIs in Python; beta support for the remote development workflow via JetBrains Gateway; and the new Jupyter notebook experience, based on a deep understanding of how to boost productivity for software developers working in the data science domain.

RubyMine 2021.3 comes with support for remote development workflows, new features for RBS and type checking, bundled RBS signatures, initial support for Sorbet, improvements for the UX and performance, and more!

DataGrip 2021.3 is here! Enjoy the long-awaited Aggregate View, which saves you from having to write additional queries! Use the independent split feature to filter and order data within two entirely separate data editor windows, and try the new database diff window to compare and synchronize your DDL data source with the real one. We’ve also expanded the workflow for working with DDL data sources, sped up introspection, and improved the Import / Export feature, among other enhancements!

DataSpell 2021.3 is here! Our brand new IDE is designed specifically for those involved in exploratory data analysis and prototyping ML models. DataSpell combines the interactivity of Jupyter notebooks with the intelligent Python and R coding assistance of PyCharm in one convenient environment.
