84 85

- Implementation:
86 87 88
   * Various bug fixes.

93

94 95 96 97 98

   * Rewrote the optimization (pushing projections).
   * The syntax for "where" clause is now simply an "and"-separated
     list of conditions ("or" is no longer supported).
   * Better types for "min","max","distinct_values" operators.

0.2.2
101

102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145
- Language:
  * Runtime type-check: (e :? t) raises an exception when e doesn't 
    have type t; the exception is an explanation of why this is not the case.
    (The actual message may change in the future.)
  * Better return type for load_xml, defined as:
    AnyXml=<(Atom) (Record)>[ (AnyXml|Char)* ]
  * New style for comments: /* ... */
    Simple and double quotes within these comments are not handled
    specially. Moreover, these comments cannot be nested.
    The new style should be used for textual comments (which can include
    the simple quote); the old style is better for ignoring pieces of code.
  * Pattern guard /p in regexps to match the current tail. This can be used
    for setting "markers" without capturing anything, e.g.:
       [ (/(x:=1) ...) | (/(x:=2) ...) ]
    Back to the old semantics for default value patterns in regexps
    (they do capture an element).
  * New syntax  {...; l = p else p'; ... }. p' is applied
    to the whole matched record when p does not match (or when
    the field is missing). Equivalent to:
    { ...; l = p; ...} | ({...;...} & p')
  * Punning in record/attribute expressions and patterns.
    { x; y } is a shorthand for {x=x;y=y}.
  * New syntax for R**n in regular expressions, equivalent
    to R...R (n times), where n > 0.
  * Interval arithmetic for the * operator.
  * Warning for potential division by 0.
  * New "system", "exit", "getenv" built-in functions.

- Toplevel, interpreter, compiler:
  * New #silent, #verbose directives.
  * New --script option.
  * Removed the warning "no caml interface".

- Compilation:
  * Better compilation of sequence capture variables.
    Now, [ ... x::Any* ] is as efficient as [ ... ; x ]. Can also be written
    [ ... /x _* ]. The [ ... ; ... ] syntax is no longer necessary
    and might be deprecated.
    
- Bug fixes, including:
  * Bug fixes in configure/Makefile for Cygwin.
  * Bug fix for the compilation of complex patterns with records.
  * Fixed a little bit support for XML Schema, but still largely broken.
  * Fix --stdin.
146
  * Bug fix in print_xml (do not create a namespace decl for "xml:").
147

148
- Distribution:
149
  * apps-cduce-cvs GODI package is updatable.
150 151
  * The release tarball does not contain the CDuce website, only
    the HTML documentation (memento, tutorial, manual).

167
  * More advanced (and documented) support for XML Schemas. 
168
  * Preliminary integration of CQL query language that is:
169 170
    select e from p1 in e1, ... ,pn in en where e'.

171
  * Default value patterns in regexps don't consume an element.
