(Alpha version.)

Thrax - Release 1.0

• Removed dependency on ICU for UTF8 string parsing: --with-icu configuration flag no longer needed and OpenFst library version 1.3.1 or above is required.
• Function definitions may now be interleaved with the rest of the body in grammars.
• Support for standard (tropical), log and log64 arc types (flag --arc_type).
• --save_symbols flag to thraxcompiler allows for symbol tables to be stored in the compiled fsts. thraxmakedep supports --arc_type and --save_symbols flags.
• StringFile function now supports construction of both acceptors and transducers. Strings may be compiled in byte or utf8 mode, or with a user-specified symbol table.
• The --rule flag to thraxrewrite-tester is now --rules. Supports a comma-separated list of rule names, which are to applied in sequence to the input.
• Project added as callable function.
• Various optimizations to CDRewrite and elsewhere.
• Fixed bug in how symbol tables are saved (1.0.1)
• Fixed bug in treatment of symbol tables with StringFile
• Adopted SET_FLAGS for better presentation of flag options

• Added interface to pushdown transducer (PDT) functionality from OpenFst.
• Added support for morphological paradigms and linguistic features.
• Added assertion capability to allow for self-testing grammars.
• Added readline support to thraxrewrite-tester to allow for inline editing and saving of histories.
• Added thraxrandom-generator to allow one to generate random strings from a grammar.
• Added more useful debug information --- grammar file name and line number --- to allow more one to find bugs in the grammar more easily.
• Generated labels are now output in readable form by thraxrewrite-tester and thraxrandom-generator.
• Generated labels (enclosed in "[]") may no longer be single-character.
• Allow ASSERT_EQUAL declarations in the grammar.

• Added interface to multi-pushdown transducer (MPDT) functionality from OpenFst.
• Added interface to Replace class in OpenFst.
• Adds --show_details flag to thraxrewrite-tester. When it is set and when multiple rules are specified, the tool will show the output of eachindividual rule. Useful when trying to find which rule caused a problem.
• Raises a warning if more than one definition is given for a function.

• AssertNull and AssertEmpty assertions added.
• Minor fixes to use fully qualified names for std:: objects.
• Rearrangement of the main compiler to have separate C++ files for each arc type.
• Fixes potential bug in Replace implementation.
• Algorithmic improvements to Optimize.

• Compatibility release for OpenFst 1.5.2.

• Properly adds AssertEmpty, AssertEqual and RmWeight functions.
• Adds fix suggested by Damir Cavar to allow for compilation under Cygwin.

• Makes "#" a comment character for StringFiles: anything from "#" to the end of the line is now a comment. If you want a real "#", escape it with "\".
• Adds a RuleCascade to the library to make it easier to deal with the common construct of a cascade of rules. (Only relevant if you develop code using the Thrax libraries.)
• Better error reporting for "cannot parse character" error.
• Adds ":" as a bash-friendly alternative to "$" when specifying a (M)PDT/parens(/assignments) combination.

• Better use of finalization in the implementation of built-in methods.
• Cleanup to string parsing.

• Adds an optional third column to stringfiles to represent weights.
• Adds implementation of lenient composition.
• Fixes some header issues that have popped up in recent versions of Debian.

• Adds some more useful debugging errors (e.g. when user tries to reuse a namespace designator)
