However, you will only get deprecation warnings if you actually use
|
||||
one of the deprecated mixins. The imports will be restored by 1.0
|
||||
with the new, betterer APIs.
|
||||
* Passing an argument to the `blueprint-scaffolding` mixin is not necessary
|
||||
and has been deprecated.
|
||||
* Some blueprint color defaults now use color functions instead of color arithmetic.
|
||||
This may result in different output for those who have color customizations.
|

### Blueprint

* Deprecations:

- Passing an argument to the blueprint-scaffolding mixin is not necessary

and has been deprecated.
|

|

* Updated from blueprint 0.9 to blueprint 1.0
|
||||
* Added detailed explanations to core uncompressed CSS files [CMM]
|
||||
* Added .info and .alert classes to forms.css [CMM]
|
||||
* Fixed numerous bugs in forms, including the fieldset padding bug in IE6-8 [CMM]
|

* Fixed specificity problems in typography.css and grid.css [CMM]

the following command in your project before you upgrade (or after temporarily downgrading):

`compass unpack blueprint`

### CSS3 v2.0
|
||||
|
||||
Our CSS3 module makes writing CSS3 today almost as easy as it will be when all
|
||||
the browsers officially support the new features. The second version of the
|
||||
compass CSS module brings the API up to date with developments over the past
|
||||
6 to 9 months of browser changes and more closely matching the most recent CSS
|
||||
specifications. Summary of changes:
|
||||
|
||||
* Support for multiple box shadows and text shadows
|
||||
* Support for 2d and 3d transforms
|
||||
* Opt-in SVG support for gradients in opera and IE9.
|
||||
Set `$experimental-support-for-svg : true` in your
|
||||
stylesheet to enable it.
|
||||
* Fixed a radial gradient position bug.
|
||||
* To generate a simple linear gradient in IE6 & 7, you can now use
|
||||
the `filter-gradient` mixin.
|
||||
* New `background-image` mixin with gradient support and allowing
|
||||
up to 10 images.
|
||||
* Gradient support for the border-image property.
|
||||
* Gradient support for list-style-image property.
|
||||
* Gradient support for the content property.

If you provide a number with units of `deg` then it will return a unitless number
|
||||
after converting to radians. Otherwise, it assumes the number is a radian length measure
|
||||
and passes the units along to the result.
|
||||
* `ie-hex-str($color)` returns a #AARRGGBB formatted color suitable for
|
||||
passing to IE filters.
|

* A new function `if()` that allows you to switch on a value without using `@if`.

|
||||
* In rails 3, there's no need for an initializer. Instead we use a

Railstie.

* We now default to app/stylesheets for sass files and public/stylesheets for
|
||||
css files -- though they can still be changed after installation or on the
|
||||
command line during project initialization.
|
||||
* Compass is now a gem plugin in a rails environment.
|
||||
* In a rails3 environment the compass configuration can now be

changed without restarting the rails server process.

|

Why? Don't ya trust me? I won't break your stylesheets. Cross my heart. All those
|
||||
200+ github issues were feature requests. Honest. But you know, they might change
|
||||
a little. Probably not in any meaningful way. Like a default that used to be
|
||||
specified in the output might be omitted because it's the browser default anyway.
|
||||
|
||||
## Trust but verify.
|
||||
|
||||
But you should probably keep me on my toes. Follow these simple steps to see
|
||||
what changed to your stylesheets:
|
||||
|
||||
*(Steps beginning with a $ are command line commands. Don't type the $.)*
|
||||
|
||||
1. $ cd my_compass_project
|
||||
2. $ compass compile --force
|
||||
3. $ cp -r stylesheets stylesheets.backup
|
||||
4. $ gem install compass --pre # you might need to type sudo first if you're on mac or linux.
|
||||
5. $ compass compile --force
|
||||
6. Take note of any deprecation warnings printed in red during the compile.
|
||||
7. If you have textmate and installed the `mate` command line tool:<br>
|
||||
$ diff -r stylesheets.backup stylesheets | mate
|
||||
8. If you have not installed the `mate` tool:<br>
|
||||
$ sudo ln -s /Applications/TextMate.app/Contents/Resources/mate /usr/local/bin/mate
|
||||
Then perform step 7.
|
||||
9. If you do not have Textmate, run the diff command like so:
|
||||
$ diff -y -r stylesheets.backup stylesheets | less
|
||||
10. Scroll or use your arrow keys to review the differences between the files.
|
||||
11. If you're satisfied: $ git commit -a -m "Upgraded compass"
|
||||
12. If you're scared again:
|
||||
A. Don't panic.
|
||||
B. Read the [CHANGELOG](http://compass-style.org/docs/CHANGELOG/) and
|
||||
see if the changes are explained there.
|
||||
B. Send an email to the [mailing list](http://groups.google.com/group/compass-users)
|
||||
explaining the problem and providing enough context like snippets from your diff
|
||||
and the relevant snippets of your sass/scss files. In rare cases we might request
|
||||
that you construct a simple compass project that exhibits the issue and make an
|
||||
archive of it and send us an email with it attached.
|
||||
C. If it's pretty obviously a bug. Please file an issue
|
||||
on [github](http://github.com/chriseppstein/compass/issues). If you're experiencing
|
||||
a crash, please run the command with the --trace option and record the output for
|
||||
diagnostic purposes.
|
||||
D. $ sudo gem uninstall compass
|
||||
Select the newest version of compass. You have now downgraded to the old
|
||||
version of compass.
|
||||
E. $ compass compile --force
|
||||
F. Diff the folders as in steps 7 through 9.
|
||||
13. Breathe a sigh of relief.
