    ```

0.2.5 Version
-----------------

* Fix config template and add `uwsgi` shell support
* Add environment variables support in `settings.ini`. For example, there is a
  `MYSQL_PORT` defined in environment, so you can defined something in settings.ini:

    ```
    [DEFAULT]
    port = $MYSQL_PORT
    port_str = '${MYSQL_PORT}'
    ```

    `$MYSQL_PORT` is the same as `${MYSQL_PORT}`. Just when the variable follows
    identifier, so `${}` can easily separate between them.
* Add `STATIC_COMBINE_CONFIG` configuration, you can toggle static combination \ 
with it.
  Default is False. The configuration is:

    ```
    [STATIC_COMBINE_CONFIG]
    enabled = False
    ```
* Fix objcache app bug, if not fields defined in settings, it'll use all columns \ 
of table
* Add `get_table` function to `functions`, you can use it to get table object. Used
  in `uliweb.contrib.tables` app.
* Add `local_cache` to local in SimpleFrame, and it can be used to store require \ 
relative
  cache values, and it'll be empty after each require process.
* Improve `get_object()` function in ORM, add `use_local` parameter, so the cached
  value will be checked in `local_cache` first, and also save it in local_cache when
  get a value from cache or database.
* Improve objcache config format, you can also define table like this:

    ```
    user = {'fields':['username'], 'expire':expire_time, \ 
'key':callable(instance)|key_field}
    #or
    user = ['username', 'nickname']
    #or
    user =
    ```

    If no fields defined, it'll use all fields of Model. And if expire is 0 or
    not defined, it'll not expired at all.

    `key` will be used to replace `id`, if you want another key value, and it
    can be also a callable object, it'll receive an instance of Model parameter,
    so you can create any key value as you want.
* Add Optimistic Concurrency Control support for ORM, so you should defined `version`
  Field first in Model, then when you save the object, you should use:

    ```
    obj.save(occ=True)
    ```

    If there is already other operation saved the record, it'll raise an `SaveError`
    Exception by default, because the version has been changed. You can also pass:

    * `occ_fieldname` used to defined the version fieldname, default is `version`
    * `occ_exception` used to enabled Exception raised, default is `True`, if you
      set it `False` it'll return False, but not raise an Exception.

0.2.4 Version
-----------------

* Fix ORM is not compatible with SQLAlchemy 0.9.1.
* add `__contains__` to functions, so you can test if an API is already defined, just
  use:

    ```
    'flash' in functions
    ```
* Refact generic.py, remove `functions.flash` and `functions.get_fileserving` \ 
dependencies by default.

* Fix `yield` support in view function, you can also used in gevent environment.
* Fix `rawsql()` bug for different database engine
* Fix `jsonp()` dumps Chinese characters bug
* Add `trim_path()` function to `utils/common.py`, it can trim a file path to
  limited length, for example:

    ```
    >>> a = '/project/apps/default/settings.ini'
    >>> trim_path(a, 30)
    '.../apps/default/settings.ini'
    ```

    Default limited length is 30.
