• Source: History of Delphi (software)

This page details the history of the programming language and software product Delphi.




Roots and birth


Delphi evolved from Borland's Turbo Pascal for Windows, itself an evolution with Windows support from Borland's Turbo Pascal and Borland Pascal with Objects, very fast 16-bit native-code MS-DOS compilers with their own sophisticated integrated development environment (IDE) and textual user interface toolkit for DOS (Turbo Vision). Early Turbo Pascal (for MS-DOS) was written in a dialect of the Pascal programming language; in later versions support for objects was added, and it was named Object Pascal.
Delphi was originally one of many codenames of a pre-release development tool project at Borland. Borland developer Danny Thorpe suggested the Delphi codename in reference to the Oracle at Delphi. One of the design goals of the product was to provide database connectivity to programmers as a key feature and a popular database package at the time was Oracle database; hence, "If you want to talk to [the] Oracle, go to Delphi".
As development continued towards the first release, the Delphi codename gained popularity among the development team and beta testing group. However, the Borland marketing leadership preferred a functional product name over an iconic name and made preparations to release the product under the name Borland AppBuilder.
Shortly before the release of the Borland product in 1995, Novell AppBuilder was released, leaving Borland in need of a new product name. After much debate and many market research surveys, the Delphi codename became the Delphi product name.




Early Borland years (1995–2003)






= Borland Delphi

=
Delphi (later known as Delphi 1) was released in 1995 for the 16-bit Windows 3.1, and was an early example of what became known as Rapid Application Development (RAD) tools. Delphi 1 features included:

Visual two-way tools
Property Method Event (PME) model
TObject, records, component, and owner memory management
Visual Component Library (VCL)
Runtime Library (RTL)
Structured exception handling
Data-aware components live at design time
Database support via BDE and SQL Links




= Borland Delphi 2

=
Delphi 2, released in 1996, supported 32-bit Windows environments and bundled with Delphi 1 to retain 16-bit Windows 3.1 application development. New Quickreport components replacing Borland ReportSmith. Delphi 2 also introduced:

Database Grid
OLE automation
Visual form inheritance
TDataModule
Long strings (beyond 255 ASCII characters)




= Borland Delphi 3

=
Delphi 3, released in 1997, added:

New VCL components encapsulating the 4.71 version of Windows Common Controls (such as Rebar and Toolbar)
TDataset architecture separated from BDE
DLL debugging
Code insight technology
Component packages, and templates, and integration with COM through interfaces.
DecisionCube and Teechart components for statistical graphing
WebBroker
ActiveForms
MIDAS three tier architecture




= Inprise Delphi 4

=
Inprise Delphi 4, released in 1998, completely overhauled the editor and became dockable. It was the last version shipped with Delphi 1 for 16-bit programming. New features included:

VCL added support for ActionLists anchors and constraints.
Method overloading
Dynamic arrays
High performance database drivers
Windows 98 and Microsoft BackOffice support
Java interoperability
CORBA development




= Borland Delphi 5

=
Borland Delphi 5 was released in 1999 and improved upon Delphi 4 by adding:

Frames
Parallel development
Translation capabilities
Enhanced integrated debugger
XML support
ADO database support
Reference counting interfaces




= Borland Delphi 6

=
Shipped in 2001, Delphi 6 supported both Linux (using the name Kylix) and Windows for the first time and offered a cross-platform alternative to the VCL known as CLX. Delphi 6 also added:

The Structure window
SOAP web services
dbExpress
BizSnap, WebSnap, and DataSnap




= Borland Delphi 7

=
Delphi 7, released in August 2002, added support for:

Web application development
Windows XP Themes
Used by more Delphi developers than any other single version, Delphi 7 is one of the most successful IDEs created by Borland. Its stability, speed, and low hardware requirements led to active use through 2020.




Later Borland years (2003–2008)






= Borland Delphi 8

=
Delphi 8 (Borland Developer Studio 2.0), released December 2003, was a .NET-only release that compiled Delphi Object Pascal code into .NET CIL. The IDE changed to a docked interface (called Galileo) similar to Microsoft's Visual Studio.NET. Delphi 8 was highly criticized for its low quality and its inability to create native applications (Win32 API/x86 code). The inability to generate native applications is only applicable to this release; the capability would be restored in the next release.




= Borland Delphi 2005

=
The next version, Delphi 2005 (Delphi 9, also Borland Developer Studio 3.0), included the Win32 and .NET development in a single IDE, reiterating Borland's commitment to Win32 developers. Delphi 2005 included:

Regained ability to compile native windows applications (*.exe) after being removed in Delphi 8.
Design-time manipulation of live data from a database
Improved IDE with multiple themes
for ... in statement (like C#'s foreach) to the language.
Multi-unit namespaces
Error insight
History tab
Function inlining
Refactoring
Wild-card in uses statements
Data Explorer
Integrated unit testing
Delphi 2005 was widely criticized for its bugs; both Delphi 8 and Delphi 2005 had stability problems when shipped, which were only partially resolved in service packs. CLX support was dropped for new applications from this release onwards.




= Borland Delphi 2006

=
In late 2005 Delphi 2006 (Delphi 10, also Borland Developer Studio 4.0) was released combining development of C# and Delphi.NET, Delphi Win32 and C++ (Preview when it was shipped but stabilized in Update 1) into a single IDE. It was much more stable than Delphi 8 or Delphi 2005 when shipped, and improved further with the release of two updates and several hotfixes. Delphi 2006 included:

Operator overloading
Static methods and properties
Designer Guidelines, Form positioner view
Live code templates, block completion
Line numbers, change bars, sync-edit
Code folding and method navigation
Debugging Tool-Tips
Searchable Tool Palette
FastMM memory manager
Support for MySQL
Unicode support in dbExpress



Turbo Delphi and Turbo Delphi for .NET


On September 6, 2006, The Developer Tools Group (the working name of the not yet spun off company) of Borland Software Corporation released single-language editions of Borland Developer Studio 2006, bringing back the Turbo name. The Turbo product set included Turbo Delphi for Win32, Turbo Delphi for .NET, Turbo C++, and Turbo C#. There were two variants of each edition: Explorer, a free downloadable flavor, and a Professional flavor, priced at US$899 for new users and US$399 for upgrades, which opened access to thousands of third-party components. Unlike earlier Personal editions of Delphi, Explorer editions could be used for commercial development.



Delphi Transfer

On February 8, 2006, Borland announced that it was looking for a buyer for its IDE and database line of products, including Delphi, to concentrate on its ALM line. Instead of selling it, Borland transferred the development tools group to an independent, wholly owned subsidiary company named CodeGear on November 14, 2006.




= Codegear Delphi 2007

=
Delphi 2007 (Delphi 11), the first version by CodeGear, was released on March 16, 2007. The Win32 personality was released first, before the .NET personality of Delphi 2007 based on .NET Framework 2.0 was released as part of the CodeGear RAD Studio 2007 product. For the first time, Delphi could be downloaded from the internet and activated with a license key. New features included:

Support for MSBuild, build events, and build configurations
Enhancements to the VCL for Windows Vista
dbExpress 4 with connection pooling and delegate drivers
CPU viewer windows
FastCode enhancements
IntraWeb / AJAX support
Language support for French, German, and Japanese
Delphi 2007 also dropped a few features:

C#Builder due to low sales as a result of Visual Studio also offering C#.
The Windows Form designer for Delphi .NET because it was based on part of the .NET framework API changed so drastically in .NET 2.0 that updating the IDE would have been a major undertaking.
Internationalized versions of Delphi 2007 shipped simultaneously in English, French, German and Japanese. RAD Studio 2007 (code named Highlander), which included .NET and C++Builder development, was released on September 5, 2007.




= Delphi for PHP

=
The CodeGear era produced an IDE targeting PHP development despite the word "Delphi" in the product name. Delphi for PHP was a VCL-like PHP framework that enabled the same Rapid Application Development methodology for PHP as in ASP.NET Web Form. Versions 1.0 and 2.0 were released in March 2007 and April 2008 respectively. The IDE would later evolve into RadPHP after CodeGear's acquisition by Embarcadero.




Embarcadero years (2008–2015)


Borland sold CodeGear to Embarcadero Technologies in 2008. Embarcadero retained the CodeGear division created by Borland to identify its tool and database offerings but identified its own database tools under the DatabaseGear name.




= Codegear Delphi 2009

=
Delphi 2009 (Delphi 12, code named Tiburón), added many new features:

Full Unicode support in VCL and RTL components
Generics
Anonymous methods for Win32 native development
Ribbon controls
DataSnap library updates
Build configurations
Class Explorer
PNG support
Delphi 2009 dropped support for .NET development, replaced by the Delphi Prism developed by RemObjects Software.




= Codegear Delphi 2010

=
Delphi 2010 (code-named Weaver, aka Delphi 14; there was no version 13), was released on August 25, 2009, and is the second Unicode release of Delphi. It included:

A new compiler run-time type information (RTTI) system
Support for Windows 7
Direct2D canvas
Touch screen and gestures
Source code formatter
Debugger visualizers
Thread-specific breakpoints
Background compilation
Source Code Audits and Metrics
The option to also have the old style component palette in the IDE.




= Embarcadero Delphi XE

=
Delphi XE (aka Delphi 2011, code named Fulcrum), was released on August 30, 2010, and improved upon the development environment and language with:

Regular Expression library
Subversion integration
dbExpress filters, authentication, proxy generation, JavaScript framework, and REST support
Indy WebBroker
Support for Amazon EC2 and Microsoft Azure
Build groups
Named Threads in the debugger
Command line audits, metrics, and document generation



Delphi Starter Edition

On January 27, 2011, Embarcadero announced the availability of a new Starter Edition that gives independent developers, students and micro businesses a slightly reduced feature set for a price less than a quarter of that of the next-cheapest version. This Starter edition is based upon Delphi XE with update 1.




= Embarcadero Delphi XE2

=

On September 1, 2011, Embarcadero released RAD Studio XE2 (code-named Pulsar), which included Delphi XE2, C++Builder, Embarcadero Prism XE2 (Version 5.0 later upgraded to XE2.5 Version 5.1) which was rebranded from Delphi Prism and RadPHP XE2 (Version 4.0). Delphi XE2 included:

Native support for 64-bit Windows (except the starter edition) in addition to the long-supported 32-bit versions, with some backwards compatibility. Applications for 64-bit platforms could be compiled, but not tested or run, on the 32-bit platform. The XE2 IDE cannot debug 64-bit programs on Windows 8 and above.
A new library called FireMonkey that supports Windows, Mac OS X and the Apple iPhone, iPod Touch and iPad portable devices. FireMonkey and VCL are not compatible; one or the other must be used, and older VCL applications cannot use FireMonkey unless user interfaces are recreated with FireMonkey forms and controls. Third parties have published information on how to use FireMonkey forms in VCL software, to facilitate gradual migration, but even then VCL and FireMonkey controls cannot be used on the same form.
Live Bindings for VCL and FireMonkey
VCL Styles
Unit scope names
Platform Assistant
DataSnap connectors for mobile devices, cloud API, HTTPS support, and TCP monitoring
dbExpress support for ODBC drivers
Deployment manager
Embarcadero said that Linux operating system support "is being considered for the roadmap", as is Android, and that they are "committed to ... FireMonkey. ... expect regular and frequent updates to FireMonkey". Pre-2013 versions only supported iOS platform development with Xcode 4.2.1 and lower, OS X version 10.7 and lower, and iOS SDK 4.3 and earlier.




= Embarcadero Delphi XE3

=
On September 4, 2012, Embarcadero released RAD Studio XE3, which included Delphi XE3, C++Builder, Embarcadero Prism XE3 (Version 5.2) and HTML5 Builder XE3 (Version 5.0) which was upgraded and rebranded from RadPHP. Delphi XE3 added:

Native support for both 32-bit and 64-bit editions of Windows (including Windows 8), Mac OS X with the Firemonkey 2/FM² framework.
FMX (FireMonkey) actions, touch/gestures, layouts, and anchors
FMX support for bitmap styles
FMX audio/video
VCL/FMX support for sensor devices
FMX location sensor component
Virtual keyboard support
DirectX 10 support




= Embarcadero Delphi XE4

=
On April 22, 2013, Embarcadero released RAD Studio XE4, which included Delphi XE4, and C++Builder but dropped Embarcadero Prism and HTML5 Builder. XE4 included the following changes:

Two new compilers for Delphi mobile applications – the Delphi Cross Compiler for the iOS Simulator and the Delphi Cross Compiler for the iOS Devices. These compilers significantly differ from the Win64 desktop compiler as they do not support COM, inline assembly of CPU instructions, and six older string types such as PChar. The new mobile compilers advance the notion of eliminating pointers. The new compilers require an explicit style of marshalling data to and from external APIs and libraries.
Delphi XE4 Run-Time Library (RTL) is optimized for 0-based, read-only (immutable) Unicode strings, that cannot be indexed for the purpose of changing their individual characters. The RTL also adds status-bit based exception routines for ARM CPUs that do not generate exception interrupts.
iOS styles, retina styles, virtual keyboards, app store deployment manager
Mobile form designer
Web browser component, motion and orientation sensor components
ListView component
Platform services and notifications
FireDAC universal data access components

RAD Studio XE6 added:

Windows 7 and 8.1 styles
Access to Cloud-based RESTful web services
FireDAC compatibility with more databases
Fully integrated InterBase support




= Embarcadero Delphi XE7

=
On September 2, 2014, Embarcadero released RAD Studio XE7, which included Delphi XE7 and C++Builder. Its biggest development enabled Delphi/Object Pascal and C++ developers to extend existing Windows applications and build apps that connect desktop and mobile devices with gadgets, cloud services, and enterprise data and API by compiling FMX projects for both desktop and mobile devices. XE7 also included:
