Agena 0.27.0 brings users an easy-to-learn yet extremely useful procedural programming language which can be suitable for everyday usage. It has been implemented as an interpreter and can be used in scientific, educational, linguistic, and many other applications. Its syntax looks like very simplified Algol 68 with elements taken from Lua and SQL. Agena provides fast real and complex arithmetics, efficient text processing, flexible data structures, intelligent procedures and package management, plus various configuration facilities.

Enhancements:

• Added the error function math.erf, and the complementary error function math.erfc.
• Added the Bessel function of the first kind math.besselj, and the Bessel function of the second kind math.bessely. The order is given by the first argument, the argument as the second argument.
• If the new environment variable _EnvIoForceError is set to a non-null value (the default), the io.open, io.readlines, and the various binio functions quit with an error instead of just returning fail.
• binio.readbytes and binio.readchar returned an empty sequence instead of fail in case the file to be read did not exist. This has been changed: fail or an error is now returned, depending on the setting of _EnvIoForceError.
• arcsin and arccos are now operators and thus around 40 % faster.
• Added the xor operator which performs a Boolean exclusive-OR on values which evaluate to or are true, false, fail, and null.
• Added the atendof operator which checks whether a word ends in a given phrase and returns its position as a number. The operator returns null if the strings have the same length, at least one of them is the empty string, or the word does not end in the given pattern.
• hasrtable now only returns true, if it has a read-write remember table (updated by the return statement).
• The new function hasrotable determines whether a function has a read-only remember table (that cannot be updated by the return statement) and returns true or false.
• The new operators gethigh and getlow retrieve the higher and the lower bytes from a number (i.e. C double).
• The new operators sethigh and setlow set the higher and the lower bytes to a number (i.e. C double).
• The new operators band, bor, bxor, and bnot conduct bitwise and, or, exclusive-or, and complementary operations on numbers.
• The bits package has been removed.
• The new `kernel` function configures settings of the Agena kernel. Currently it can change the way the bitwise operators internally work (usage of signed or unsigned integers), and how numbers are printed.
• With real numbers x, math.argument now returns Pi instead of 0 if x < 0.
• Because of a bug in the underlying ANSI C library functions on UNIX systems, arcsin and arccos produced wrong results with complex numbers if their imaginary part was zero. This has been fixed.
• math.isPrime reported false with number 2. This has been corrected.
• As opposed to the manual, abs returned 2 for fail. Now it returns -1, as documented.
• Added the new C API function agn_isioforcerror which checks whether _EnvIoForceError has been set to a non-null value.
• The new C API function agn_setbitwise determines whether the operators band, bor, bnot, bxor, and shift internally calculate with either signed or unsigned integers.
• The new C API function agn_getbitwise returns the mode set by agn_setbitwise.
• The new C API function agn_setdigits sets the number of digits used for printing numbers.
• The new C API function agn_getdigits determines the number of digits used for printing numbers.
• Internal: Removed deprecated "REPL" entry from luaP_opnames.
• The Windows installer has been improved by now checking for a previously installed version of Agena, by preventing that the installer is started if another instance of it is already running, and by some other small improvements.
