- Support for Visual SourceSafe integration.
- Registers window can now display bitfields.

##### Assembler

- Now recognises the EXTERN declaration (in addition to EXTRN) to be compatible with IAR.
- Type checking implemented to ensure that byte and word writes are to items of same widths.

##### Archiver

- -c option fixed to remove old members of an existing archive.

##### Target Interfaces

- Added support for Rowley USB CrossConnect and SoftBaugh Replicator connected to a CrossConnect.
- FET is now supported with a custom designed device driver which enables usage of plug-in parallel port cards, predictable download performance and device serialisation.

## Changes in Release 1.1.1

##### Compiler

- Added binary constants which are written with a leading 0b, e.g. 0b1010 is 10 decimal. Binary constants are signalled with a warning when the -ansi command line option is given. The C preprocessor also supports binary constants.
- Corrected a problem in the switch statement as in some cases the 1.0.0 compiler would destroy the contents of a register used in the expression.
- The long double type is now treated identically to the double type when Treat 'double' as 'float' is set to Yes.
- Single-bit bitfield manipulation and access now generates much denser code.
- Correctly implemented the __monitor function attribute to support Salvo from Pumpkin, Inc.
- Corrected a corruption problem on return when a multi-register value is allocated to coincide with the function return registers.
- The compiler now fragments the code of a function which enables further size reduction optimizations by the linker.
- Code generation for 0(SP) source address is now always coded using @SP which reduces the size of code.
- for statement generation now recognizes more special forms and codes appropriately.
- Narrowing and widening conversions corrected to ensure that new registers are used when required.
- Corrected a code generation problem compiling x *= y when -mmpy specified.
- Corrected a problem in the spiller which caused incorrect code generation on reload.
- Corrected optimization applied for x & y when y is non-constant.

##### Target Interfaces

- The FET target interface now has a RAM Fill Value property that is used to fill the RAM before a program is downloaded. If this property is empty, the RAM is not filled and is left intact. You can use the RAM Fill Value as a watermark to see how far the stack descends during program execution.
- Added the PRGS430 Serial Programmer target interface to support the Texas Instruments PRGS430 serial programmer.
- Added the SoftBaugh Flash Replicator target interface to support the SoftBaugh flash replicator.
- Added the Gessler Flash Bootloader target interface to support the Gessler flash bootloader.

##### Editor

- Added a setting to allow or disallow Cut and Copy from cutting and copying the current line if there is no selection.
- Added a setting to disable the numeric keypad '–' and '+' keys from being used as Cut and Copy (as they are in Brief).
- Added themes to the Environment Options dialog.
- Made Shift+Insert a synonym for Paste in all contexts.
- Made Ctrl+Insert a synonym for Copy in all contexts.
- Made Shift+Delete a synonym for Cut in all contexts.
- Corrected a crash when editing long lines of plain text without syntax highlighting.
- Corrected syntax highlighting problems with multi-line comments and preprocessor continuations.
- Added a VHDL syntax highlighter.

##### Assembler

- Fixed PC-relative addressing mode offset computations.
- The C compilers preprocessor is now integrated into the assembler.

##### Linker

- Corrected PC-relative addressing mode offset computations.
- User symbols can now replace symbols defined in the library; required to support Salvo from Pumpkin, Inc.
- Added a few micro-optimizations including branch switching.
- The section start and end symbols have been renamed to allow them to be accessed from C.
- The linker now supports section checksum generation using the -H option.

##### Archiver

- The archiver no longer uses PKZIP format for its archives in order to be portable to Linux.

##### C Library

- Added missing __int8_lsl_asgn and __int8_lsr_asgn runtime support routines.
- Corrected__vfprint.c which causes __vfprintf_long not to recognize "%l" format strings correctly.
- Added debug_scanf function.
- The debug_getx functions now take input from the debug I/O console.

##### CrossStudio

- Added new project types for all SoftBaugh, Olimex, and TI boards.
- Added a new project wizard to assist in setting up a project.
- The New Folder dialog is reworked and presents example file filters.
- New projects now have the runtime startup code automatically placed into the project and do not use the standard startup object module.
- Solutions can now be created on drives other than the drive containing CrossStudio.
- Fixed incorrect reporting of file permissions on NTFS and network drives.
- The Evironment Options dialog now displays all properties that are also settable through the Properties Window.
- There is an all-new Build Properties dialog (Alt+Enter) that is much easier to use than the previous dialog.
- The user interface can be switched between the tabbed interface and an MDI-style interface.
- Project files can now be linked into other project files - most of the project dialogs have had to be upgraded to support this.
- Configurations now have a hidden property which causes them to be hidden from the configuration combo box.
- Created a new project type to enable externally built executables can be built/loaded and debugged.
- Solutions are now created using the new project wizard.
- Linker section placement can now be done using a file that is separate to the memory map file.
- Project system can create an additional output file for example S-Record.
- Special function registers window added which displays the registers defined in the memory map file used to link the project.

- Breakpoint dialog rehashed to support MSP430 EEM - can now trace breakpoints and specify register write breakpoints.
- Support for specifying the clock control on MSPF149 and EEM enabled parts.
- Exception support for PC not in FLASH range on EEM enabled parts.
- Register write breakpoints.
- Fixed problem with printing variables from assembly code.
