## 2011.11.23, Version 0.2.3

*   Added `--engine`, `-e` option and new `sort-group` engine. Moved all
    old engine-specific code into engines/fullgen.js and made it default

*   Sort-group engine - much faster and simplier compilation algorithm.
    (17 minutes on fullgen for a large template, and 7 seconds on sort-group)

*   Ported code to new ometajs module

*   Optimized code size for client-side usage (removing hanging braces, shorter
    merge function names, localStart/localEnd => "")

*   Documented most of the source, released docco gh-pages

*   Much better apply optimizations

*   xjst.compile() returns function (see readme)

*   --no-opt - just compile template and locals

*   -u, --uglify - uglify js output

*   --merge, -m - add merge info for client-side template merging

## 2011.11.3, Version 0.1.5

### API Changes:

*   Split ometa into Parser, Translator, Compiler. Parser+Compiler isn't
    translating locals.

*   Given string as first argument xjst.compile() will return compiled and
    evaluated version of template

*   Given array (ast-tree) as first argument xjst.compile() will return source
    code (compatibility mode)

*   New arguments: xjst.compile(source, filename, options).

    `filename` is used for evaluation (visible in stack traces).
    `options`: `wrap` (default: true) - wrap code into
    `(function(exports){...})()` statement.
    `merge` (default: false) - adding hash information required for merging
    templates.

*   Introduce `apply` keyword:
    `apply() => this.apply()`, `apply(x = 1) => local(x = 1) this.apply()`,
    `apply({ x: 1 }) => local(this.x = 1) this.apply()`

### Various changes

*   Recursion optimization.
*   Big switches will be split into hashmaps
*   Split parts of code in functions to simplify optimization for v8
*   Use coa for cli
*   Benchmarks and tests
