A small effort has been made to support some of the Apple Pascal syntax to ease interfacing to the Classic Mac OS and macOS.

The 2.2.x release series did not significantly change the dialect objectives beyond roughly Delphi 7 level syntax, instead aiming for closer compatibility.

Student Florian Paul Klämpfl began developing his own compiler written in the Turbo Pascal dialect and produced 32-bit code for the GO32v1 DOS extender, which was used and developed by the DJ's GNU Programming Platform (DJGPP) project at that time.

The DOS port was adapted for use in OS/2 using the Eberhard Mattes eXtender (EMX) which made OS/2 the second supported compiling target.

For the 1.0.x releases, the port to 68k CPU was redone, and the compiler produced stable code for several 68k Unix-like and AmigaOS operating systems.

During the stabilization of what would become 1.0.x, and also when porting to the Motorola 68k systems, it was clear that the design of the code generator was far too limited in many aspects.

In 2006, some of the major reworks planned for 2.2, such as the rewrite of the unit system, had still not begun, and it was decided to instead start stabilizing the already implemented features.

Some of the motives for this roadmap change were the needs of the Lazarus integrated development environment project, particularly the internal linker, support for Win64, Windows CE, and OS X on x86, and related features like DWARF.

Another major feature was the internal linker for Win32, Win64, and Windows CE, which greatly improved linking time and memory use, and make the compile-link-run cycle in Lazarus much faster.

The unit system rewrite was postponed again, and the branch that became 2.4 was created to keep risky commits from 2.2 to stabilize it.

Other compiler improvements included whole program optimization (WPO) and devirtualization and ARM embedded-application binary interface (EABI) support.

Later, during the 2.2 cycle, a more Delphi-like resource support (based on special sections in the binary instead of Pascal constants) was added.

This first version from the 2.6 release series also supported Objective Pascal on OS X and iOS targets and implemented many small improvements and bug fixes.

Free Pascal 3.0.0 also supports ARMHF platforms like the Raspberry Pi, including ARMV6-EABIHF running on Raspbian.

With InstantFPC it is possible to run Pascal programs, which are translated just in time, as Unix scripts or CGI back-end.

Ultibo core is an embedded or bare metal development environment for Raspberry Pi.

Ultibo is an OS-less runtime and has support for most functions and allows the programmer full control over the hardware via the RTL units.

The programmer can put threads on a specific CPU or let the runtime divide the load automatically or a mix of the two.
