FireDAC and Database
Improvements for Firebird
- New Direct property to add support for the Direct I/O backup feature.
Improvements for MySQL
- Support for MySQL v 5.7.
- Support for MariaDB v 5.5 or later. Use FireDAC's MySQL node to connect to MariaDB.
- Compatibilty with the recent MySQL versions 5.6.x and 5.7.x.
- MySQL Prepared Statements API: now both old API (MySQL text protocol) and PS API (MySQL prepared statements protocol) are supported.
- You can select a desirable API using the TFDResourceOptions.DirectExecute property.
- Depending on the API in use, the TFDCommand.CommandIntf.CliObj property returns a TMySQLStatement or TMySQLResult object.
- Support for internal BLOB streaming (in the smOpenWrite mode only).
- Improvements for a synchronization of a connection transaction state and the TFDConnection.InTransaction property. This property allows you to determine whether a connection transaction is currently in progress.
Database improvements
- VCL TDBImage direct support for JPEG and PNG graphic formats.
- Support for display options for BlobFields.
- Direct GUID access for TField classes.
RTL
HTTP Client
- HTTP Client Library provides support for 64-bit Linux.
- Improved async support in HTTP client.
RTL support for 64-bit Linux
- RAD Studio 10.2 Tokyo provides Linux file system support using standard system functions, streams, and the IOUtils unit. It also provides Standard RTL Path Functions support for 64-bit Linux.
App Tethering Improvements
App tethering gains the following features:
- New SynchronizeEvents property for TTetheringManager and TTetheringProfile to control the event synchronization with the main thread. Therefore, Managers and Profiles can now control whether their event handlers are executed on the main thread or not.
- Improved support for Log filtering: added more logging messages.
IDE
- Code Insight and Code Completion for Delphi now correctly handles static and dynamic arrays.
- The Find In Files dialog works on screens with high DPI.
- Support for designing and opening forms at different DPIs has been improved.
- The View Menu has been re-arranged. Tool windows such as the Object Inspector, Structure, Messages, etc have been moved to a Tool Windows submenu just below the existing Debug Windows submenu, and a new Editor submenu contains a number of editor actions and useful features from the editor's context menu. Other items have been moved to keep related items adjacent to each other.
- The context menus for the code editor tabs and files in the Project Manager now have a "Show In Explorer" menu item, which will show the file's location in Explorer.
- The project's manifest file support now supports several execution levels: As Invoker, Highest Available, and Require Administrator, and also allows the UI Access flag to be set.
- IDE loading speed should be fast even with high network load or a missing network connection.
- Support for building very large project groups, such as those with over a hundred projects, has been improved.
iOS debuggers
- Full support for iOS10 debugging (from a 10.1 Berlin hotfix).
- Full support for iOS Simulator debugging (from a 10.1 Berlin hotfix) - Delphi only.
- Writing Delphi string values is supported in the iOS debugger.
- Evaluating character arrays gives the expected result.
- Errors ending the debug session (also on macOS) are resolved.
macOS debuggers
- Full support for macOS Sierra debugging (from a 10.1 Berlin hotfix).
- Errors ending the debug session (also on iOS) are resolved.
Linux debuggers
- Support for debugging on Linux (Delphi only).
VCL
High DPI fixes
- Improved High DPI support:
- Form bounds are now correctly adjusted in response to WM_DPICHANGED messages, meaning TForm.AutoScroll works correctly, as well as the form's top/left position
- Forms open at the correct scaling factor when the system has multiple monitors with different DPIs
- TTabSheet and TPageControl, and controls placed on tab sheets or page controls
- ActionMainMenuBar when moving a form across monitors with different DPIs
- VCL menus (both main menus and popup menus) now display correctly on high DPI monitors
- TStatusBar's height remains correct in high DPI
- Message dialogs' icons are now scaled correctly
- Anchored controls now stay in the expected position when moving a form between monitors with different DPIs
- TCheckBox and TRadioButton paint correctly
- Several issues with form inheritance, including that controls now use the correct font size when placed on a panel with ParentFont set to true on an inherited form, and TListView column sizes remaining correct on an inherited form.
GetIt installer
- Enhanced parallel downloads.
Cloud
- Improved Azure and AWS support with updated APIs.
Compilers
- Delphi command line compilers are now large-memory-address enabled, allowing you to compile larger applications from the command line (and matching the memory available to the compilers when invoked in the IDE).
- Given that dynamic arrays are managed types, involving reference counting and associated helper function generation, casting array elements using the @ operator is disallowed as it leads to memory corruption. Performing a similar operation is still allowed using an explicit cast operation, under the developer responsibility.
iOS 10 Simulator, device, and macOS
- Full support for iOS 10, including iOS 10 32-bit and 64-bit debugging on device, Simulator support (Delphi only) and macOS Sierra support.
