Embarcadero Technologies announces the General Availability of C++Builder 12.1.

C++Builder 12.1 primarily focus on improving the quality of the new features in C++Builder 12, addressing regressions, and focusing on customer-reported issues. At the same time, Embarcadero has completed the development of the new C++ Win64 Clang–based compiler and toolchain, which was previewed in 12.0.

New Features in C++Builder 12.1

Modernized C++ Compilers and Toolchain

The first release of the new Clang-based C++ compiler for Win64, a high-quality toolchain with excellent STL support, 64-bit compiler and linker, great for building and linking large applications, integrating better with external libraries and C++ code. Includes full IDE integration and the ability to build VCL and FireMonkey apps, using FireDAC and other database and RTL libraries.

Split Editor Views in RAD Studio IDE

In RAD Studio 12.1, the IDE supports split editor views: multiple editors side by side, above and below each other. Split editors allow the same file to be edited next to itself, allowing you to edit the same file in multiple locations and to keep both a design and a code view on screen.

Android API Level 34 and Improved Deployment

RAD Studio 12.1 is updating the supported Android API to level 34. This has been done in advance of the August 2024 deadline for Google Play Store app submission, which will require API Level 34. This change required updates to the Android SDK, the introduction of some additional Android platform tools, an update of the Java runtime, and improvements to the app packaging process.

Quality Improvements in C++Builder 12.1

Improved Visual Assist Integration for C++Builder IDE

Visual Assist integration was introduced in 12.0 and has been significantly improved with a strong quality focus in 12.1, as well as expanding rename refactoring to rename across code and visual designers. It provides best-in-class code completion, code navigation and refactorings for C++ code; an amazing productivity boost.

VCL and FireMonkey Quality

RAD Studio 12.1 has dozens of improvements to both the VCL and FireMonkey libraries, with specific focus on features introduced in RAd Studio 12.0. New foundation improves performance and quality in rendering graphics and UI controls across all target platforms.

  • A new FireDAC Query by Example (QBE) component for easier data filtering and a new JSON wizard for Delphi to add a mapping of the data in the popular JSON format to objects, like we have for XML
  • Many IDE productivity and quality improvements, to make it easier and faster to use RAD Studio for every day tasks
  • Support for smart IDs in RAD Server, to make customer’s hosted REST APIs more powerful and flexible, while maintaining RAD Server easy-of-use

C++Builder 12 – New Features Deepdive

Wonderful Things for C++

A significant focus of this release is on C++Builder and our C++ toolchain (available also in RAD Studio). The team has been focused on two key C++ improvements: modernizing our C++ compilers and toolchain, and providing amazing productivity with code completion as well as adding refactoring and navigations by integrating Visual Assist.

The C++ toolchain upgrade is an amazing overhaul of our C++ support. It includes not just a new version of Clang, but also the C and C++ runtime libraries and the STL (the C++ Standard Template Library) plus the linker and debugger. The goal of this large effort is to offer modern C++ standards, with the ability to run C++ code you find in recent libraries and projects, easily use third party libraries, leverage modern safe coding standards, have more performant apps and excellent debugging. It also aims to directly improve areas like linking and the STL, and moves to Windows platform standards such as using the COFF and PDB object and debug formats, potentially allowing you much wider compatibility with other tools. You can read more about this feature in this preview blog post:

In 12.0, we are shipping a Preview of this new C++ toolchain, available as a command line compiler.  We’ll continue working on the IDE integration of this new C++ toolchain, in parallel with the existing C++ compilers, and on the integration with the Delphi libraries in RAD Studio, including the VCL and the FireMonkey UX libraries. We plan to make these updates available to customers on subscription as they become available. 

Another significant innovation for C++Builder in 12.0 comes from the integration of the Visual Assist technology to offer better Code Insight including code completion, code navigation and refactoring. These are key productivity tools that assist in common development tasks, from code completion which is invoked often while coding, to navigation which allows developers to easily find relevant parts of their code instead of manually searching a codebase, to refactorings which help code organization and safety. We’ll have a significant initial subset of the VA features available within RAD Studio, including finding symbols and references, showing the project Outline, navigating from implementation to declaration and back, and rename refactoring.

FireMonkey and Skia as a New Foundation

In terms of UI libraries the most significant set of improvements in RAD Studio 12.0, for both Delphi and C++Builder, comes from the integration of the very popular cross platform rendering engine Skia, in FireMonkey. This is done by integrating the Skia4Delphi open source project, but also extending it with Vulkan support, support for effects and filters with the Skia Shading Language, a WebP Encoder, printer support, and printing to PDF. 

RAD Studio Skia support includes direct APIs, specific UI controls (TSkAnimatedImage, TSkLabel, TSkPaintBox, and TSkSvg), and the automatic mapping of FireMonkey UI controls UI rendering via Skia. In general terms, Skia improves the quality of the rendering and the performance. Notice that the same Skia UI controls are also available in the VCL windows library.

screenshot 2023 11 06 at 10 35 12 pm

Outside of Skia support, which offers a new solid foundation for the future of the library, we have improved our Android support matching many recent platform enhancements, added split screen support, to allow FireMonkey application to work in a side-by-side pane on both iOS and Android, and extensively  reworked the text input capabilities of the single-line TEdit and multi-line TMemo controls. 

Another significant improvement to the IDE, for FireMonkey development, is the introduction of a wizard to generate icons and splash screens at all of the resolutions, required by Apple and Google, starting from a single SVG image and the support for Android’s adaptive icons, as you can read in

VCL Modernization with MDI and Tabbed UI architecture

We have been doing VCL modernization work to help our customers migrate their existing applications (often very large and well established in their target industry). In 12.0 the focus is on keeping alive the old fashioned, but still popular, MDI (Windows’ Multi Document Interface) model. With the new release customers will be able to adopt full HighDPI support for MDI applications and also adopt VCL styles. We’ll allow our customers to bypass platform issues caused by the fact Microsoft has been neglecting support for MDI in recent years.

screenshot 2023 11 06 at 10 35 37 pm

In addition, RAD Studio 12.0 introduced a new tab-based UI (like the one from Google Chrome and many other popular apps) as an easy migration from MDI or a brand new model, with the new TFormTabsBar control. The VCL library has improvements in futons management for High DPI screens.

As part of the VCL improvements, the new release is introducing a number of new designers to help simplify the work: There is a new string list editor, a multiline string editor, and quick configuration dialogs for buttons, radio groups and panels. Some of these handy tools were originally part of KSVC (Konopka Signature VCL Controls) and are now available to anyone, even without installing this add-on control pack.

screenshot 2023 11 06 at 10 34 23 pm

Beside the core RTL definitions, we have created a new set of units with the complete Windows API headers converted to Object Pascal, to make it easier for Delphi developers to call any Windows platform API we don’t expose in our component libraries. This API conversion includes 311 Delphi header files with 41 MB of code, covering the entire platform API provided by Microsoft.

Additionally, we have improved the Edge browser integration with new interfaces, properties and events, matching the improvements to the platform WebView 2 control since our last release. Further improvements in the VCL with noticing are an extremely flexible TControl enumerator, Desktop Windows Manager (DWM) enhancements, and changes to Double Buffering mode.

New In Delphi RTL, Data, and Other Areas

There are many improvements in other Delphi core runtime libraries, leveraged also by C++ Builder. For our flagship database access library, FireDAC, we have added support for the classic QBE mode (Query-By-Example) which allows the development of a UI for entering simple data filtering criteria. 

In addition, FireDAC components offer some additional functionality to help developers improve their application security, by limiting the type of SQL commands for a specific query control, forbidding multiple commands, and blocking further SQL changes. These improvements offer developers the ability to improve the application security, if used alongside other industry best practices.

RAD Studio 12.0 also introduces a new JSON mapping wizard, which can generate classes matching a JSON data structure and proper reading and writing code to read the JSON in a set of objects and stream it out to a new file.

RAD Studio IDE Improvements

There are many relevant changes in the IDE. 

The first is a new UX for the feature installer, used for the initial product installation or to add features and platforms later on. This dialog box has been completely redesigned in behavior and in the UI, using modern VCL controls, which improves the first impression of the product for new users. It’s easier to use because all major installation options including extra addons are on one page, unlike the previous multi-step design. The new dialog also offers better error information, in case of installation problems.

screenshot 2023 11 06 at 10 49 13 pm

The IDE has now syntax highlighting in many secondary windows, like the call stack and structure view. There are also improvements in source code searches, in the way the navigation toolbar works, and in the use of multiple edit windows, plus many other small tweaks.

Besides the introduction of Visual Assist integration for C++Builder, we have also done further improvements in the DelphiLSP support used for Code Insight. For example, code completion now includes language keywords, and code templates are shown in contextually correct areas of code during completion, as well as having better support for generics and completing arrays or array types.

Finally, the RAD Studio further extends the new ToolsAPI for the code editor to let customers and third party vendors create more flexible plug-ins for our IDE.

RAD Server and InterBase

There are some notable improvements for RAD Server, our REST server API hosting platform. The most significant change is the ability to easily support a smart ID model, using a standard library to define better identifiers for resources exposed by the server. RAD Server also offers better performance, data paging improvements, better session authentication and overall quality.

Finally, the new version of RAD Studio includes the developer edition and the embedded versions of recently released InterBase 2020 Update 5.

Quality, Quality, Quality

In addition to the features highlighted above, the release has been focused on quality work in multiple subsystems, starting with the IDE, but including also the Delphi RTL libraries, the VCL UI library, the FireMonkey cross-platform library, FireDAC and other data access layers, HTTP client and server components and RAD Server.

In RAD Studio 12, we implemented fixes for 1,027 issues reported by customers on Quality Portal (, addressing 877 public bug reports and implementing 150 customer requests for new features.
