Enough people are using calc now that I feel the need to start using some better documentation practices, like a ChangeLog. But I don't want to hold myself to the high standards which regulate "proper" ChangeLog entries, so I'm calling it "README.whats-new" instead. 2019-05-29 calc.2.6 : * This is a significant refactor which incorporates some of the features of calc3 (which is a separate work in progress). * The most significant interface difference from 2.5 is that the accumulator is now $A instead of $a. 2005-10-22 calc.2.5 : * When the user input evaluates to a hash reference, calc will display the result as a series of "x=y" tuples, rather than displaying HASH(0xNNNNNNNN). * Many more functions in .calc.code * Included summary of .calc.code functions in README.calc.code 2003-11-16 calc.2.4 : * More functions in .calc.code (and much better documentation thereof). * Added optional GNU-Readline support. * If you do not want calc to use GNU-Readline, add this line to your .calc.code file: $CALC_use_readline = 0;
