 ### 0.1:
 - A new `interval_parameters` object stores information about the current interval precision and rounding mode
 - Macros for interval creation completely reworked: `@interval` generates intervals based on the current type
+  stored in `interval_parameters`
 - Newton and Krawczyk methods improved and stringent tests added
 - Two types of interal rounding methods are now available:
   - narrow / slow;  wide / fast   (Though they are not really very wide at all)
-- Trigonometric functions are now rigorous
+- Trigonometric functions are now "nearly" rigorous (for `Float64` intervals correct rounding is not guaranteed)
 - Inverse trigonometric functions added
