+* 1.0.0
+** Language:
+- Addition of initializer list metavariables. Thanks to Michael Stefaniuc
+ for noticing the need for them.
+- Allow multiple position variables per token
+- ++ can now be associated with - code
+- Allow /* */ comments as smpl comments, not only as + code
+- Add support for && (label addresses)
+- local idexpression metavariable no longer matches static local x
+- Consider using to be a comment in C++ code. Patch submitted by Jani Monoses.
+- Command line cocci
+- print_main etc for ocaml Coccilib
+- =~ not ~= is used to indicate a regular expression constraint on an
+ identifier. And !~ for a nonmatch.
+- allow long double, short int, long int, and long long int in SmPL code.
+- gcc constructors allowed in SmPL. Thanks to Uwe Kleine-Koenig for
+ pointing out the problem.
+- Allow ! to appear before () in depends. Thanks to SF Markus Elfring for
+ noticing the problem.
+- Can add code containing #pragma or #line.
+- Multicharacter command-line options now begin with -- and contain -
+ rather than _.
+- Allow multiple types of hidden metavariables, each preceded by @.
+ Position variables can be attached to these.

+ elements for list metavariables. Thanks to Michael Stefaniuc for
+ suggesting this features.

+ not as elements of specific structures.
+
+** Features:
+- Preserve spacing before // comments when not at the beginning of a line
+- Adjusted parsing of endif to put it after jump code
+- Improve warning message when using -use_cache
+- More helpful initial value for exported variables in python
+- Support - on expression nests
+- Better handling of the case of a matched declaration that should only
+ be replaced by other top level things.
+- Allow a semantic patch beginning and ending with braces to match the
+ complete body of a function if the braces are not removed and if nothing
+ is added before the first brace or after the last one.
+- Add -cache_prefix option, to specify where to put cached files.
+- Allow module_init(foo); to match module_init(foo) (or likewise for any
+ declarer), when no transformation is specified on the semicolon.

+ to abort the treatment of the current file.
+- Don't multiply print the same patch for the same file
+- Drop date in diff
+- Don't repeat smpl type warnings
+- -sp_file/-cocci_file are now optional. If not present an argument that
+ ends in .cocci is assumed to be the name of the file containing the
+ semantic patch.
+- Allow limiting the size of a named cache using -cache_limit
+- Cache name specified with -cache_prefix is extended according to the
+ index (parallelism), if any.

+ typedefs.
+- Implement newes as a hash table, for more efficiency on big sets of
+ environments.
+- A local variable that is declared without a type is not considered to be
+ a local variable. Actually, such a variable is probably really a macro

+ inplace.

+ identifier bindings.

+- Cause appropriate newlines to be preserved when multiple matches (trees)
+ contain adjacent modifications derived from the same SmPL code.
+- check_meta takes into account fresh identifier seed information.
+- Types for worth-trying optimization should not be followed by space
+- Improved filtering of result of matching atomic patterns
+- Drop positions before creating function prototype rules

+ single-statement position
+- Drop newline after function call ( when all arguments on that line are
+ eliminated
+- Accept removal of a single declaration, replaced by arbitrary,
+ non-declaration code

+ were discarded

+ Stefaniuc for pointing out the problem.
+- Propagate dependencies further in get_constants2
+- Make lexer more dos friendly
+- slightly better handling of long long

+ before comparison, due to incomparability of pcre regexps.
+- Fixed obsolete regexp doc, thanks to Dmitry Osmakov
+- Improved x || ... || y to avoid double modification
+- Transparently allow \( \| and \) to be on lines beginning with -. The -
+ has no effect.

+ Thanks to Robert Gomulka for noticing the problem.
+- Fix interpretation of dependencies in the presence of virtual rules.
+ Ignore constraints on inherited position metavariables in a rule that
+ will be ignored.
+- Better support meta iterator and meta declarer tokens, and symid tokens.
+- Better indentation after added noindent.
+- Fixed length bug in the treatment of structures.
+- Allow inheriting declaration/field metavariables.
+- Don't drop spaces after parentheses in when no minus code present.
+ Thanks to Terry Wilson for reporting the problem.
+- Keep inherited metavariables in asttomember (preprocessing for matching)

+* 0.2.5

+ multiple variables
+- allow #endif XXX in C code
+- relax_include_path now applied to non local includes too, in which case

+- support matching and removing #undef
+- support for iteration in ocaml, requires use of -no_show_diff
+- calls to likely and unlikely propagate test expression status to their
+ arguments
+- reuse typedefs and macros from complete parsing when reparsing the
+ transformed code
