 ### Filter Arguments Improvements
 
-In 0.11, filters always receive their arguments as plain strings. An argument can be enclosed in quotes to include whitespace, but the quotes are not automatically stripped when passed into the filter function. Some users were also confused about how to retrive a dynamic value on the vm instead of a plain string.

An argument can be enclosed in quotes to include whitespace, but the quotes are not automatically stripped when passed into the filter function. Some users were also confused about how to retrieve a dynamic value on the vm instead of a plain string.
 
 In 0.12, the filter argument syntax now follows a simple rule: if an argument is enclosed in quotes, it will be passed in as a plain string; otherwise, it will be evaluated against the current vm as a dynamic value.

+1. The original intention of these benchmarks were for comparing Browser performance rather than that of frameworks. The "synchronously trigger an action xxx times" test routine doesn't reflect meaningful real world user actions.
 
 2. Due to internal implementation differences, frameworks that uses async rendering (e.g. Vue, Om, Mercury) gains the advantage by skipping part of the calculations that happened in the same event loop. The real world user experience doesn't demonstrate such dramatic difference.

 ## Additional Notes
 
-Designers may change their minds. Product requirements change. Keeping the logic for the entire icon system in one base component means you can quickly update all of your icons and have it propogate through the whole system. Even with the use of an icon loader, some situations require you to recreate or edit every SVG to make global changes. This method can save you that time and pain.
