Go

an open source project developed by a team at Google and many contributors from the open source community

Go 1.9 is planned to be released in August.

There won't be any radical changes; creators of Go 1.9 are focused on maintaining compatibility in this latest release, so no compatibility issues are expected.

New features:

  • Garbage collector's performance improved and core library is optimized; it will make programs run better;
  • The math/bits package offers optimized implementations to manipulate bits. Functions in this package are treated by the compiler as intrinsics to boost performance.
  • The Go 1.9 compiler supports parallel compilation of functions in a package, leveraging multiple processor cores. Go 1.9 retains the previous versions’ go command’s support for parallel compilation of separate packages. Parallel compilation is on by default but can be disabled. 
  • Type-alias declaration for code repair is now added to Go 1.9 in order to increase scalability. A change to the Go language, type aliases support gradual code repair while moving a type between packages.
  • Transparent monotonic time now supported. This will make computing durations between two "Time" values a safe operation in the presence of wall-clock adjustments.
  • Test helper capabilities improved.
  • New type added. It serves as a concurrent map with amortized-constant-time loads, stores, and deletes.

GoLand 2018.3 to be Released by JetBrains

New version of IDE for Go programming language has a lot of new features
22 November 2018   377

Team JetBrains introduced a new version of IDE GoLand 2018.3. In this update, users will see:

  • refactoring by changing the signature;
  • memory dump;
  • Testify support;
  • new debugger tools;
  • Improved verification, prediction and code completion;
  • chart support;
  • updates for VCS, Docker, Kubernetes.

The new method of processing the code Change Signature will allow a single action to change the signature of functions and methods throughout the workspace. The function will show what will change in the code after application. The Inline tool will highlight the embedded code, and Rename will notify you of possible conflicts when renaming.

Added the ability to run and debug Google App Engine applications locally.

Go memory dumps are now available via Run / Open Core Dump directly in the IDE. To automatically create memory dumps, you need to enter GOTRACEBACK = crash in the Environment field.

Also, GoLand 2018.3 supports the Mozilla debugger rr, which allows you to search for a crash in the program by playing back its execution.

The previous version of GoLand 2018.2 was released in July 2018.
