Embarcadero planned to release Delphi 10.5 but decided to switch to the 11 to match the Windows 11 version number, like they did back then with Windows 10.
Future wise it really is justified to increase the Major version Number instead of just a minor increase.
Check out the big list of changes below!
The RAD Studio 11.0 Alexandria release contains the following new and improved features:
The Delphi, C++Builder and RAD Studio IDE are now high-DPI enabled. Running with high DPI enabled is currently a runtime option. All windows in the IDE now support high DPI. This includes behavior such as changing scale when being dragged from one monitor to another. IDE functionality refers to:
The IDE styles (Light, Dark and Mountain Mist) have been updated to support high DPI as well.
In RAD Studio 11.0, the VCL form designer can handle scaling three different ways. You can customize this inside Tools > Options > User Interface > Form Designer > High DPI. The options available are Automatic (Screen PPI), Low DPI (96 PPI) and User Editable when you can set a specific PPI value.
The FireMonkey designer scales a form the same way a FMX form does at runtime. Coordinates remain the same (that is, a button placed at (20, 20) will be at (20, 20) no matter the high DPI scaling of the monitor the FMX designer is on.) It is a visual scaling only.
A new VCL-based Welcome Page has been added to the IDE. It is designed to:
All APIs that pass images, such as the splash screen services, about box, IDE Insight, and other areas have been updated to support high DPI images. This allows you to pass in multiple resolutions of the same icon, which are added to the internal image collection and used with a virtual image list. Although the methods take an array of any TGraphic, we recommend PNG images.
VCL controls can be optionally rendered using styles in the designer.
The StyleName property editor reflects the available styles in the project, and renders a preview (how a button looks). Remember that if you select “Windows” it means platform styling and if you leave the property empty, it is going to use the parent control (or parent form) style.
Notice that the VCL form designer now has a custom Windows 10-style title bar and frame, rather than using the classic Windows frame. If no form style is set, it uses a Windows 10 style. If the form is set to use a VCL style, the frame reflects the selected style of the form.
In 10.4.2, the Design tab was disabled when a form was being designed in another window. Now, the tab is always enabled, but if it is being designed in another window a message is displayed; you can click a button to bring the designer to the current window.
The Options dialogs (both IDE and Project Options) should load in a fraction of the time of previous releases. In the past, all pages were loaded when the dialog opened; now, a page is loaded (and controls created) only when it needs to be shown.
Third party vendors should be aware of this change for impact on their settings frames.
The FireMonkey designer in version 11.0 is introducing guidelines and other features found in the VCL designer, with a different implementation. Components hints are displayed when you are moving or resizing them. Also, controls offer guidelines for alignment on the sides and display standard margins distance with a line across.
The form and component resize controls now have the same look and feel as the VCL form designer.
In RAD Studio 11.0 DelphiLSP can be used with other editors. As part of this, we have created a Visual Studio Code extension using DelphiLSP.
To know more about this feature, see here.
LSP in RAD Studio 11.0 focuses on quality and ensures it is a robust replacement for classic Code Insight. Key improvements include being able to parse units that have include files included in them; improvements around when the server is restarted; and improvements to the syntax elements the server understands.
Delphi classic code completion has been removed from the IDE. Only the LSP option is available for Delphi Code Insight.
Build events can execute arbitrary commands on your system. It is common to get projects, which include build events, from third parties online. RAD Studio now warns when a project contains a build event in any configuration (including one you are not currently building.)
The code editor now uses Consolas as the default font. A number of other common coding fonts, such as Fira Code, are installed with the IDE. Note that the editor does not support ligatures, but it does render high DPI text crisply using these new fonts. ‘View Messages’ has been restored to the editor context menu.
The Code Insight progress bar is hidden once work is completed.
RAD Studio 11.0 supports a new Delphi target platform, macOS ARM 64-bit, to natively target the new M1 Apple Silicon CPUs with macOS 11. You can use this platform to build native M1 applications (of course this requires M1 hardware to run). We keep our Intel 64-bit target support and the creation of Universal Binary applications including both ARM and Intel binaries in a single package.
You can create a universal binary containing both Intel and ARM code. To do so, ensure the target platform is macOS ARM 64-bit. In the Project Options (ensuring macOS ARM 64-bit is the current target) navigate to Building > Delphi Compiler > Compiling > Other, and check ‘Generate macOS universal binary file (x86_64 + arm64)’. Make sure you deploy the application, you can find the universal binary file under the OSXARM64\Debug folder.
In the RAD Studio 11.0 release, Macapi.QTKit unit is deprecated on macOS/X64, and it’s removed from macOS/Arm64 library. We also removed the "Macapi.Quicktime" unit from the product for both the macOS/X64 and the Arm64 libraries.
The Delphi language in Olympus adds support for binary literals, in addition to decimal and hexadecimal ones. A binary literal uses the % symbol as a prefix (the same syntax used by other Pascal compilers):
const
Four = %100;
var
x: Integer;
begin
x := %1001001;
The language also introduces a digit separator that can be used to improve the readability of literal values with many digits. The separator is the underscore “_” and it is basically ignored when parsing and compiling the code. This is very similar to the feature introduced in C# 7.0.
const
AMillion = 1_000_000;
Of course, you can use the digit separators for binary literals.
We have introduced support for asm code for newer sets of instructions, including AVX2 (ymm) and AVX512 (zmm).
The code formatter technology used for C++ has been completely replaced. Code formatting now uses clang-format. The new formatter options for C++ are found in Language > C++ > Formatting. You can always format code manually, but you can also have the IDE automatically format your code when you save, or even as you type. These last two are controlled by the ‘Auto formatting’ setting. Set it to format on save, or format on newline.
The IDE will use format settings specified by a .clang-format file in the source folder, a common C++ project convention. If one is not found, it will use whatever format you choose in the Options dialog (above), where the default is the Embarcadero recommended formatting.
We now have C++-compatible RTTI available for Delphi types; you can use make_shared on a Delphi type, and there are type conversions to assist in using Delphi types in C++.
In the past, C++ type information was not available for Delphi types; that is, accessing the result of typeid(delphi-type) where delphi-type is a type that comes from Pascal code, or is a Delphi-style class in C++, would result in an AV. Note that typeid returns a std::typeinfo for a type simply, or if it’s a polymorphic type for the most-derived type of that instance.
typeid() now returns a std::typeinfo, and C++-compatible RTTI is generated for Delphi types.
You can now use both std::make_unique and std::make_shared on a Delphi-style class (one defined in Delphi, or in C++ but inherited from one defined in Delphi.)
The RTL now includes helper methods for type conversions between Delphi types and C++ (and Delphi) strings. This includes conversions from TDateTime to string types, as well as being able to easily convert (assign) from a C++ string to a Delphi string, and use std::string_view on a Delphi string. Type conversions to and from strings There are now to_string() and from_string() methods for many types to convert to and from strings (UnicodeString, WideString and AnsiString, including templated by codepage). These methods exist for the following types:
In RAD Studio 11.0 we have done a large collection of small improvements to the VCL library, focused on removing some remaining XP legacy and inconsistencies with Windows 10 and improving core library features.
We updated the implementation of the VCL TRichEdit component to support a more recent version of the platform control. Additionally, TDBRichEdit.Lines is now a public property. RichEdit URL detection has new features like EnableURLs, ShowURLHint and SetSelTextToFriendlyURL.
Some changes were made to the RichEdit Text Attributes, it now has additional properties like BackColor, Disabled, Hidden, Link, Offset, RevAuthor and Subscript. TParaAttributes has also new types and a new property. Finally TCustomRichEdit now has a new public method.
For VCL applications, the default font is now Segoe UI 9. The title font of the VCL styles is getting adapted to the same default font.
New property in TCustomMemo, published in TMemo, TDBMemo, TRichEdit, TDBRichEdit.
In TCustomGroupBox we have this public property published in TGroupBox, that contains ShowFrame, HeaderFont and DefaultHeaderFont.
There are two new properties in TCustomComboBox and descendants (public in the TCustomComboBox class, published in the TComboBox class) that are DropDownWidth and AutoDropDownWidth.
Now TTreeView defines new properties that support CheckBoxes. You can read more about this here.
TWICImage multi frame support, there are 2 new properties in type TWICImage defined as FrameCount and FrameIndex. These two properties together allow you to read all valid frames in a multi-frame image file.
There is now a data-aware version of the TLabeldEdit VCL control. To implement it, the hierarchy of the related controls has changed:
Additionally, RAD Studio 11.0 adds support for the TLabeledEdit control in the TFlowPanel and TGridPanel containers.
Coolbar has Chevron support via a new Boolean property ShowChevron.
The TNumberBox class introduced in 10.4.2 has a few additional features:
In general, UI controls should be created in the main UI thread. If you create a VCL control in a background thread, the behavior is undefined and can lead to fairly obscure access violations.
For this reason, there is a new class property: TControl.RaiseOnNonMainThreadUsage
When this property is True, the VCL will raise an exception in case a TWinControl window handle is created in a thread that’s not the main thread. This prevents issues when this is done by accident. In COM scenarios and other cases, the creation of a handle in a secondary thread might be legitimate and so it remains allowed.
The include file StyleUtils.inc has been converted to a regular unit, allowing developers (and component vendors) to better integrate their code with VCL styles support. The previous include file, in fact, defined private types generally impossible to modify and extend, unlike the new unit.
For FireMonkey we have focused on some core refactoring, with particular focus on desktop and Windows in particular. Now platform services for macOS and Windows refactored into separate units, extended IFMXMultiDisplayService and TDisplay, extracted all metrics related services into FMX.Platform.Metrics, constraints size for forms, and refactoring of:
TWebBrowser component for Windows extended with support for Chromium Edge via the platform WebView 2 component, similarly to the existing VCL TWebBrowser support. You can pick the browser engine using the new WindowsEngine property of TWebBrowser.
RAD Studio 11.0 offers support for the latest version of Google’s Billing API, an update that’s becoming mandatory later this year for Play Store apps (the final deadline is November ‘21). The new API is integrated seamlessly with the FMX library and your code should adapt easily to the new API.
Android API 30 support includes the following changes
Also, for Android, RAD Studio now supports the “multidex” feature (which allows your app to generate multiple “classes.dex” files) and uses the newer “D8” DEX compiler instead of the old “DX” one to compile Java bytecode into DEX one. The new releases include a different set of Java libraries and this makes old projects incompatible. When you open an Android project build with an older version of RAD Studio you need to:
There are many improvements in the core RAD Studio libraries. Here we are providing a summary of the key changes across RTL, FireDAC, HTTP and REST client libraries and more.
RTL adds a new platform identifier, pidOSXArm64 for the macOS/Arm64 platform. The existing pidAndroid32Arm and pidAndroid64Arm identifiers are replaced by the new pidAndroidArm32 and pidAndroidArm64. Now, all platform related identifiers use the same format and order of the compilers: <Platform name> <Architecture name> <Bitness>
We have focused on ZIP files (that is, the TZipFile class of the RTL) quality, improvements, and optimizations. We added support for Zip64 and a method to remove a file in TZipFile. Also, TZipHeader has a GetFIleName method, TZipFile.IsValid() accepts a stream parameter and System.Zip works with files larger in size than 4 GB.
We have made a few improvements in the use of proper data types for larger memory structures under 64-bit compilers. For example, TMemoryStream in 64-bit supports data structures larger than 2 GB. Related to this, we added the new method TThread.GetTickCount64 (while the existing TThread.GetTickCount, returning a 32-bit value, remains in the RTL for compatibility).
There is a new record helper for TDateTime, which includes a “UTC Now” function (not available in the original Date RTL), actually called NowUTC. This release also introduces a helper for the TCurrency data type in Delphi, TCurrencyHelper, similar to the TDoubleHelper.
Improvements in this area include both classic Bluetooth and Bluetooth LE and most platforms, with particular focus on Windows 10 and Android (but also iOS and macOS). Improvements also include Beacons support.
When using multiple generic types, some generic collections used to have TKey and TValue as symbolic names for the generic types. Now this is confusing as TValue is a specific type in the RTL. To avoid any confusion the symbolic names have been changed. There is no effect to existing code, as the symbolic names are replaced with concrete types when the generic types are instantiated. Additionally, there are few additional constructors for collection classes, that take as parameters an array of values, including:
procedure DoCheckStateChanged(Node: TTreeNode; CheckState: TNodeCheckState);
virtual;
constructor TList<T>.Create(const Values: array of T);
constructor TDictionary<TKey, TValue>.Create(const AItems: array of TPair<TKey, TValue>);
The implementation of TDictionary Capacity, GrowThreshold and hashing has been improved, with a better balance of performance / memory usage / minimal collisions. The internal implementation class TListHelper has been removed in favor of using a strongly typed field TArray<T>, updating all related streaming and data mapping code.
Open array support to RTTI: allows invoking methods with an open array parameter via RTTI and also supports open array arguments in TVirtualMethodInterceptor. TValue adds specific support for TDateTime. Also, TValue and Variant type interchange has been improved.
Made the PPL Thread pool statistics easier to access, that means, TThreadPoolStats.Get method is now public
New TPointerStream class, allows reading and writing in-memory data using the TStream interface, by indicating a pointer location and a size. TStream.CopyFrom doesn’t require the size, which might be unknown. The method has also been optimized when Count is large (up to 400% improvement).
Dates to strings and reverse conversions have been improved. Worth to note, that now StrToDate strictly follows ‘to date’ format string, supports date formats with month and day names, and supports date formats with arbitrary text inside. Also improves TFormatSettings date/time related properties initialization and unifies the representation on all platforms.
There is a new System.Generics.Defaults._MakeInterfaceInstance that allows creating an interface instance, where all interface methods are represented by anonymous methods.
The new class System.TNoRefCountObject is a non-reference-counted IInterface implementation (replacing the old and oddly named TSingletonObject)
Improved the performance of:
The TGUID data structure is now defined only in System.pas
The UTF8ToString overload that accepts an array of AnsiChar has been removed and UTF8ToString(array of Byte) deprecated. The removed function is: UTF8ToString(const S: _PAnsiChr.
Please see System.UTF8ToString for workarounds.
ISAPI DLL threads have a configurable StackSize, using the variable Web.Win.ISAPIThreadPool.StackSize. Significantly improved WebBroker performance when sending/streaming files larger than 2 GB (MaxInt).
Multipart/form-data support for RAD Server
DataSnap: The REST URI is now configurable using a new mechanism, based on a TDSMethodMapEvent event
RAD Studio 11.0 installer has several changes worth noticing:
