 # fixedincome 0.0.2
 
-* Added `progagate` slot to `Interpolation` class. It defines if the interpolation method is propagated to interpolated curves.
+## Term class
+
+* Term class accepts multiple units.
+* `toyears` returns Term objects
+* New methods `tomonths` and `todays` for Term conversion in different units.
+
+## SpotRate
+
+* SpotRate Compare method split into spectific methods: ==, !=, >, <, >=, <=. The methods >, <, >=, <= raise error for objects with different slots: compounding, daycount, calendar.
+* SpotRate Arith methods raise error for objects with different slots: compounding, daycount, calendar.
+
+## SpotRateCurve
+
 * The curve methods `[` and `[[` don't propagate interpolation. The returned curves don't have interpolation. This avoids recurrent `prepare_interpolation` calls.
+* New SpotRateCurve method `[[` for missing returns interpolated curve in curve's terms.
+* SpotRateCurve converts terms to `days` units, so `days` units becomes the default units to SpotRateCurve.
+
+## Interpolation
+
+* Added `progagate` slot to `Interpolation` class. It defines if the interpolation method is propagated to interpolated curves.
 * The `interpolate` function, for NelsonSiegel and NelsonSiegelSvensson models, converts `term` argument to years with `toyears`.
 * Organized nelsonsiegel and nelsonsiegelsvensson code.
   * New objective functions (and their gradients) have been created to improve the optimization.
-* New SpotRateCurve method `[[` for missing returns interpolated curve in curve's terms.
-* SpotRate Compare method split into spectific methods: ==, !=, >, <, >=, <=. The methods >, <, >=, <= raise error for objects with different slots: compounding, daycount, calendar.
-* SpotRate Arith methods raise error for objects with different slots: compounding, daycount, calendar.
-* `toyears` returns Term objects
-* New methods `tomonths` and `todays` for Term conversion in different units.
-* Updated to bizdays version 0.1.10 (Issue #21)
+
+## Compounding
+
+* `rates` method has been renamed to `implied_rate`
+
+## Misc
+
 * Code refactoring
+* Updated to bizdays version 0.1.10 (Issue #21)
