Changes in JMurmel-1.4.5 relative to JMurmel-1.4.4
released: 2023-12-31

 * changed (fixed?) the commandline parameter --eval: environment is no longer reset before REPL
   so that e.g.
     jmurmel --repl --eval (load \"mlib\")
   will work as expected
 * added the primitives lisp-implementation-type and lisp-implementation-version
 * (declaim (optimize (debug 0))) omits "loc =..." in compiled code

Changes in JMurmel-1.3.1 relative to JMurmel-1.3

Changes in JMurmel-1.3 relative to JMurmel-1.2.2
released: 2022-11-12

 * changed car and cdr so that they are no longer defined for symbols, i.e. (car 'aaa)
   now is an error.
 * changed the evaluator of the interpreter so that lists whose car is 'lambda' are
   no longer valid functions. e.g.
     (apply '(lambda (a b) (+ a b)) '(1 2))
   no longer works but gives an error.
   Old behaviour can be restored by the commandline flag '--XX-oldlambda' (interpreter only).

   * list->string now has an optional parameter: (list->string lst [adjustablep])
 * added seqref, seqset
   seqref is similar to CL elt, seqset is similar to CL (setf elt)
 * added the global variables @-, @+, @++, @+++, @*, @**, @***, @/, @//, @///
   to the environment inside the REPL.
   If you remove the leading @ then these work similar to Common Lisp's REPL variables.

 * mlib: added generator related functions and macros
   * scan
   * scan-multiple, scan-concat
   * dogenerator

Changes in JMurmel-1.2.2 relative to JMurmel-1.2.1
released: 2022-05-20

 * macroexpansion is no longer done on-the-fly but in a seperate macroexpansion phase.
   This fixes issues with macros being expanded that are actually defined later,
   or expanding the wrong version of a macro that is defined more than once.


Changes in JMurmel-1.2.1 relative to JMurmel-1.2
released: 2022-05-07

 * changed the interpreter to expand macros only once
 * changed the compiler so that the restriction "The list containing optional arguments cannot be used
   as an argument to `rplacd`." no longer exists

 * added the commandline argument --script, allow #!...!# as multiline comment to support hashbang scripts.
 * added --final-result and --no-final-result

 * fixed the compiler to tailcall-optimize let/let* dynamic


Changes in JMurmel-1.2 relative to JMurmel-1.1
released: 2022-04-20

 * changed/ fixed the behaviour around large numbers, no more silently cutting off decimal places
   when an integral number is needed
 * changed argument to sleep to "seconds" (was: internal-time-units-per-second),
   changed return value to nil (was: actually slept time in internal-time-units-per-second)
 * changed/ fixed "apply" from a special operator to a function, "apply" no longer is a reserved word,
   "apply" now accepts symbols as the first argument as well
 * changed "::": renamed to "jmethod", static Java methods no longer want "nil" as a first (ignored) argument
 * changed macroexpand-1 to return multiple values as one would expect
 * changed setq to create undefined variables on the fly in interpreted mode

 * changed mlib: dotimes, dolist and doplist accept multiple result-forms (in an implicit progn)
   (was: only the first one was eval'd, the rest were silently ignored)
 * changed mlib: inplace modification macros (incf, decf...) now process 1 or more args
   (was: 1 or 2 arguments, anything more was silently ignored)

 * added the function "jproxy" to implement Java interfaces with Murmel code
 * added values, multiple-value-call and multiple-value-bind
 * added primitive functions assq, list*
 * added an optional parameter print-escape-p for primitive functions write, writeln, lnwrite
 * added special operator "(declaim (optimize..."
 * added limited support for "macroexpand-1" in compiled code (quoted forms only)
 * errormessages contain the filename and linenumber (was: only linenumber)
 * added more complete support for "let dynamic" and "let* dynamic"
   (before 1.2 only "let* dynamic" in interpreted code was supported)
 * [f]round, [f]floor, [f]ceiling and [f]truncate now support 1 or 2 arguments (was: 1)
 * compiled code now can invoke interpreted closures
 * added some benchmarks and found some speedups
 * added some JFR integration

   circular-list, compose, multiple-value-compose, conjoin, disjoin, curry, rcurry, doplist,
   unzip, unzip-tails,
   with-accumulator, summing, collecting, reverse-collecting, plist-keys, plist-values

 * backquote expansion generates more efficient code
 * some functions are "opencoded" (i.e. trampolines and/ or argcount checks are omitted,
   regular Java code is emitted instead)
 * fixed compiler primitive "list" to return a mutable list
 * fixed compiled "let*"
 * fixed "append" for compiled code
 * fixed using rplaca on varargs list
 * fixed/ cleaned up feature-flags
 * fixed search directory for load and require
 * fixed defmacro to support multiple body forms
 * fixed handling of symbol names such as \(\b^2\)\ -\ 4*\a*\c

released: 2022-01-03

 * added feature expressions #+, #-, and, or, not
 * added reader macros #b #o #f for binary, oct and hex, #\ for characters,
   accept (and ignore) #'
