2023.1 (May 2023)

Overview
The new release brings some long awaited features. As you might remember for the last release we removed the old deprecated library for code formatting. In the current release formatting is back based on clang-format. Also TheIDE has got a special dialog when you can adjust formatting to your needs. Formatting is available under "Assist" -> "Reformat" menu.

2022.3 (December 2022)

Release highlights

• Homegrown C++ parser in theide is replaced with libclang resulting in new and improved Assist++ features
• Autocomplete now correctly works in most cases (except in template bodies, which is libclang limitation)
• Code navigator refactored and improved
• TheIDE now shows C++ errors while editing sources
• TheIDE now shows information tips about program symbols when you leave mouse over it (documentation if available, declaration signature if not)
• New function "Usage" shows all usages of current symbol through all project sources based on C++ analysis. With virtual methods, it shows all overrides of base class method.

2022.2 (May 2022)

Release highlights

• Core: IsVoid(String) function to avoid confusion with IsVoid(Value)

2022.1 (April 2022)

Release highlights

• sizeof(wchar) is changed to 4 (32 bits) to support non BMP unicode characters

This might bring some incompatibilities in the code that expects wchar to be 16 bit, which
escpecially involves dealing with Win32 (and to lesser extend MacOS) APIs, so if your application
is doing that, please check all instances of WCHAR (UniChar on MacOS) or even wchar
especially type casts.... read more

U++ 2017.1 (rev 10804) (Jan 2017)

This is the first release of U++ that requires C++11 compatible compiler. The main focus was Core, adding many enhancements allowed by C++11 and improving parallel programming support. We, also didn't forget about Android as we ported Core library on that platform.

Changelog

Core

• Original U++ Callbacks are deprecated and replaced with Function with better lambda support.
  Begin/End methods are now renamed / deprecated in favor of (standard) begin/end.... read more

Leap second of 2015 added to time routines.

GUI programming & graphics

Improved support of UHD displays.

U++ is BSD licensed C++ cross-platform rapid application development framework focused on programmers productivity without sacrificing runtime performance.

Overview

New features for release 2015.1 (rev 8227)
