Changes since development release 0.2.2

** Parsing enhancement: Support for Unicode

SCSS now transforms Unicode escape sequences to the appropriate Unicode
characters. Note that since Guile versions prior to 1.8 don't support Unicode, 
escapes that refer to characters over and above the first 256 characters won't 
be replaced in Guile 1.6 or earlier.

** Assorted minor bugfixes

Character backslash escapes without a special meaning should be replaced by the
character itself; the parser was failing to reject invalid values for certain
generalized properties (background, border, border-*, font, list-style, 
outline, and text-decoration).


Changes since development release 0.2.1

** Major cascade lookup bugfix

If the best selector match contains a rule for a property that is a more
general version than the property requested AND is inherited from an ancestor
node, SCSS will now correctly use this property.

** New API function: scss:clear-style-cache!

For greater efficiency in performing style lookups, SCSS maintains internal
hashes mapping nodes to matching style information. scss:clear-style-cache! can
be used to clear this cache when it is necessary to perform a full lookup from
the cascade. See the SCSS documentation for more information.

** Assorted minor bugfixes

Formatting of imported stylesheets when there are multiple @import directives
has been fixed; requests for "border-color" will now properly generalize to
"color."


Changes since development release 0.2.0

** Vastly improved performance

As part of some fixes to query algorithm correctness, there is a welcome side-
effect: SCSS queries now take an order of magnitude less time to complete,
making SCSS a whole lot more useful as an embedded style-management system.

** Changes to internal stylesheet representation

Pursuant to the optimizations mentioned above, the stylesheet format has
changed; detailed information can be found in the documentation, but developers
relying on direct access to SCSS stylesheets will need to update their code.


Changes since development release 0.1

** Property generalization improvements and bugfixes

If the best selector match contains a rule for a property that is a more
general version than the property requested, such as "border" for a lookup of
"border-left-style," SCSS will now correctly use the more general property to
determine the value of the requested property.

** Assorted bugfixes

Among others, bugs related to the !important modifier, color-to-hexadecimal 
conversion, and stylesheet emitting have been fixed.

** Documentation is complete

The SCSS API should now be fully documented.
