Version 1.2.3

This release contains a fix for a bug: use of uninitialized data. Such data was only used when outputting an error message, but I am striving for perfection. As Michelangelo said, "Trifles make perfection, and perfection is no trifle."

Version 1.2.0

This is a production release.

There have been several changes since 1.1.0:

• The build system had some changes.
• Locale support has been added. (Patches welcome for translations.)
• The ability to turn ibase, obase, and scale into stacks was added with the -g command-line option. (See the bc manual for more details.)
• Support for compiling on Mac OSX out of the box was added.
• The extended math library got t(x), ceil(x), and some aliases.
• The extended math library also got r2d(x) (for converting from radians to degrees) and d2r(x) (for converting from degrees to radians). This is to allow using degrees with the standard library.
• Both calculators now accept numbers in scientific notation. See the manuals for details.
• Both calculators can output in either scientific or engineering notation. See the manuals for details.
• Some inefficiencies were removed.
• Some bugs were fixed.
• Some bugs in the extended library were fixed.
• Some defects from Coverity Scan were fixed.

Version 1.1.1

This release fixes a bug in the 1.1.0 build system. The source is exactly the same.

The bug that was fixed was a failure to install if no EXECSUFFIX was used.

Version 1.1.0

This is a production release. However, many new features were added since 1.0.

1. The build system has been changed to use a custom, POSIX shell-compatible configure script (configure.sh) to generate a POSIX make-compatible Makefile, which means that bc and dc now build out of the box on any POSIX-compatible system.
2. Out-of-memory and output errors now cause the bc to report the error, clean up, and die, rather than just reporting and trying to continue.
3. Strings and constants are now garbage collected when possible.
4. Signal handling and checking has been made more simple and more thorough.
5. BcGlobals was refactored into BcVm and BcVm was made global. Some procedure names were changed to reflect its difference to everything else.
6. Addition got a speed improvement.
7. Some common code for addition and multiplication was refactored into its own procedure.
8. A bug was removed where dc could have been selected, but the internal #define that returned true for a query about dc would not have returned true.
9. Useless calls to bc_num_zero() were removed.
10. History support was added. The history support is based off of a UTF-8 aware fork of linenoise, which has been customized with bc's own data structures and signal handling.
11. Generating C source from the math library now removes tabs from the library, shrinking the size of the executable.
12. The math library was shrunk.
13. Error handling and reporting was improved.
14. Reallocations were reduced by giving access to the request size for each operation.
15. abs() (b command for dc) was added as a builtin.
16. Both calculators were tested on FreeBSD.
17. Many obscure parse bugs were fixed.
18. Markdown and man page manuals were added, and the man pages are installed by make install.
19. Executable size was reduced, though the added features probably made the executable end up bigger.
20. GNU-style array references were added as a supported feature.
21. Allocations were reduced.
22. New operators were added: $ ($ for dc), @ (@ for dc), @=, << (H for dc), <<=, >> (h for dc), and >>=.
23. An extended math library was added. This library contains code that makes it so I can replace my desktop calculator with this bc. See the manual for more details.
24. Support for all capital letters as numbers was added.
25. Support for GNU-style void functions was added.
26. A bug fix for improper handling of function parameters was added.
27. Precedence for the or (||) operator was changed to match GNU bc.
28. dc was given an explicit negation command.
29. dc was changed to be able to handle strings in arrays.
