+- Allow multiple position variables per token
+- ++ can now be associated with - code
+- Allow /* */ comments as smpl comments, not only as + code

+- 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.
+
+** Bugfix:
+- Corrected parsing of script strings delimited by a single quote. Thanks
+ to Eugeniy Meshcheryakov for reporting the problem.
+- Improved indentation of added ifdefs.
+- Allow added comments and #ifdefs to precede other added code. Thanks to
+ Jani Monoses for noticing the problem.
+- Corrected failure to due missing ocamlfind. Thanks to Derek M. Jones for
+ reporting the problem.
+- Allow fake nodes to be - in the allminus case, to drop tokens related to
+ a function definition or forward declaration but before the first code
+ mentioned in the semantic patch.
+- Drop __init etc when deleting a whole function.
+- 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.

+- Drop positions before creating function prototype rules
+- Adjust position of { introduced by adding multiple statements in a
+ single-statement position
+- Drop newline after function call ( when all arguments on that line are
+ eliminated

+- smpl_spacing takes into account newlines, indentation
+
+* 0.2.5
+** Language:
+- Make a very small attempt to parse C++ code, amounting to accepting
+ identifiers containing ::, tilde, and template invocations. Use the
+ option -c++. This is not likely to be very useful in practice.
+- Added metavariable metavariable type.
+- Add disjunctions on identifiers in some contexts
+- Pretend that & indicates a pointer in -c++ mode
+- Support for new and delete
+- Allow arrays in smpl parameter declarations. Thanks to Jesper Louis
+ Andersen for pointing out the problem.

+- Slightly improved the error message for transformation on multiple
+ variable declaration. Thanks to Jonathan Nieder for pointing out the
+ problem.
+
+** Features:
+- support transformations on variables (only) in declarations that declare
+ multiple variables
+- allow #endif XXX in C code
+- relax_include_path now applied to non local includes too, in which case
+ it tries to find a unique file with a suffix of the provided name.
+ this is useful for directories that are intended to be symbolic links.
+- 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
+- better explanation when presenting glimpse tokens
+- optimization for an if branch that is just { ... }
+- spatch -control_flow_to_file file.c generates a file file.dot

+- removed use of the no longer supported sexplib function Conv.hashtbl_of_sexp
+- add information about which Fedora packages are needed
+
+** Bugfix:

+ more places
+- Fix check_config for Python 2.7 on Fedora 14 (Reported-by: Michael Stefaniuc)
+- Check for ocamlfind in configure (Reported-by: Paul E. McKenney)
+- Postpone use of ocamlfind at runtime to report fewer errors
+- Add support for Python 2.4 binding with the provided pycaml library
+- Allow '@' in script code. Thanks to Laurent Reveillere for noticing the
+ problem.
+- Remove an optimization of x or true to true in asttoctl2 for the case
+ where x may make a modification, eg the case of -thing ?-thing
+- Allow adding comments before a function.
+- Introduction of newlines in function arguments needs to take into account
+ that the code added by SmPL can include newlines. Thanks to Thomas
+ Gleixner for finding the problem.
+
+* 0.2.4
+** Language:
+- scripts now have names and can declare metavariables that are seen by
+ SmPL as identifier metavariables, see demos/{python,ocaml}tococci.cocci
+- declaration (match variable declarations) and field (match structure
+ field declarations) metavariables
+- matching of array initializations and of enum declarations
+
+** Features:

+ out the problem
+- python and ocaml string representations of parameter lists and expression
+ lists

+- struct *^* and enum *^* metavariable types
+- allow an assignment to match a variable initialization, even if multiple
+ variables are declared at the same time.

+ script idutils_index.sh
+
+** Bugfix:
+- detect used after metavariables in simple statement metavariable match
+- allow inheriting position variables over rules that make transformations
+ but depend on virtual rules that are not defined on the command line

+- avoid adding an error message to standard output if ocamlfind is not
+ found
+- struct/union/enum-typed metavariables with a metavariable type name
+- better management of whitespace between deleted lines. Thanks to
+ Andriy Gapon for noticing the problem.
+- improved parsing recovery for badly parsed struct/enum typedefs
+- drop expanded tokens in sgrep output. Thanks to Andriy Gapon for
+ noticing the problem.
+- constant strings have array type, not pointer type. Thanks to Vasiliy
+ Kulikov for noticing the problem.
+- improve indentation when adding code after a function call with indented
+ arguments.
+- return type of sizeof converted to unsigned long. Thanks to Vasiliy
+ Kulikov for noticing the problem.
+- improve spacing when adding structure initializers. Thanks to Vasiliy

+
+* 0.2.3
+** Language:
+- <= constraints relating an expression metavariable to one or more
+ inherited expression metavariables that it should be a subexpression of
+- the -inplace and -outplace options have been renamed -in_place and
+ -out_place. -in_place no longer makes a backup. A backup can be
+ requested using the option -backup_suffix, eg -backup_suffix .bk

+ identifier metavariable, or from a set containing both concrete
+ identifiers and inherited identifier metavariables.

+- more graceful failure on finding a strange character in a macro parameter
+ list
+- support Parameter metavariables
+- add space after the last comma in an added portion of an argument list

+- allow removed field between two ... in structure initialization
+- allow removing an entire structure initialization
+- manage labels within do while 0 macros

+- allow unknown as type for array indices in SmPL
+- support matching of static annotation on functions that are both static
+ and inline

+ an include file is in a subdirectory that exists but is an ordinary file,
+ not a directory.
+- better management of unbound position variables that appear in
+ constraints
+- cause python parser to skip over // comments, hoping that // is not
+ meaningful inside python
+- require + on every line of a multiline comment
+- correct calculation of line numbers when there is script code

* 0.2.1
** Language:
- Add virtual identifiers
- isomorphisms don't apply under signed/unsigned, to prevent the creation
of things like unsigned signed int. Need a better solution for this.
-
* 0.1.3
