+Ragel 6.2 - May 9, 2008
+=======================
+ -Bug fix: The lm_switch actions needs to set p from tokend when there is no
+ user action.
+ -Bug fix: when not using indicies we can't use a transitions's id to identify
+ the eof transition to take. Instead add the transition to the end of the
+ transition list and store its position in a new var called pos. The pos var
+ is then used as the index.
+ -Bug fix: an fnext followed by an fbreak in -G2 was not working. The fbreak
+ was not aware that the fnext causes the cs variable to be forced active. In
+ this case fbreak does not need to save cs because it is already current.
+ -Bug fix: need to compute the low and high character-space keys from the
+ condition-trans overlap when computing an expansion. Can't use the range
+ supplied from the condition overlap since they may not match. An incorrect
+ machine that accepted 1(!cond1, !cond2) was generated for the following
+ grammar. This bug was reported by Tim Chklovski.
+ c = 2 @matched_c;
+ sc1 = 1..2 when cond1;
+ sc2 = 1..2 when cond2;
+ main := sc1 | c | sc2;
+ -Bug fix: error messages in start label analysis of join operations were
+ causing assertion failures because location info was not set. Fixed by
+ adding locations.
+ -Include and import file searching now searches for the file name given based
+ on the location of the current file, not ragel's current path.
+ Additional search locations can be given using the -I option.
+ -Rubinius code generation was updated to the latest Rubinius. Patch from Evan
+ Phoenix.
+ -Switched from strcasecmp to strcmp for testing long arguments.
+ -Applied a patch from Andrei Polushin for setting the error message format.
+ --error-format=gnu (default)
+ --error-fromat=msvc
+ -Now using the _WIN32 define instead of _WIN32. Other MSVC compilation
+ improvments from Andrei Polushin.
+ -Added the hyperref package to the manual.

+Ragel 6.1 - Mar 26, 2008
+========================
+ -Scanners now ensure that any leaving actions at the end of a pattern are
+ executed. They are always executed before the pattern action.
+ -Added an option -d for turning off the removal of duplicate actions from
+ actions lists.
+ -Need to unset the final state status of the start state in kleene star if it
+ is set. It is possible to crash ragel when the warning is ignored.
+ -In the dot file generation we need to print any actions that are in
+ State::eofTrans. These come from scanners only.
+ -Use @docdir@ for the docdir Makefile variable.
+ -Check for ar and ranlib in the configure script.

+Ragel 6.0 - Jan 12, 2008
+========================
+ -Removed the 'noend' write option from examples/atoi.rl. This example is
referenced a lot as a first example and as such it shouldn't contain a
special purpose write option like 'noend'.
-Introcuded the "eof" variable for indicating the end of file. The p variable
now used to emulate gotos.
-Ruby code generation was also restructured. Gotos are elmulated using a
series of if tests.
- -Gone back to 3.X semantics for >, % and error actions. The > operator also

executed. If EOF happens in a non-final state that has an error action, the
error action is executed.

same name in case we are executing from the source tree.
-Changed the -l option in rlgen-cd to -L because it is covered in the
frontend. Added a passthrough in the frontend for the backend options.

on the java compiler which can run out of memory compiling very large

-The fbreak statement now advances p.
-In the :> :>> and <: operators it was possible for the priority assignment
to be bypassed via the zero length string. In :> this was fixed
If the start state is final it now embeds a leaving action into it,
preventing persistance through the zero length string. In :>> and <: this
was fixed explicitly. With <: the entering priority operator was used and

transition operator it also adds a leaving priority to the start state if it
is final.
-Ranlib is now run on the archives. Patch from Kenny MacDermid.
