+### Breaking Changes
+
+Some features of this library were marked deprecated for a long time and have been removed with Version 2.0:
+
+- Aliases of display\_width (…\_size, …\_length) have been removed
+- Auto-loading of string core extension has been removed:
+
+If you are relying on the `String#display_width` string extension to be automatically loaded (old behavior), please load it explicitly now:
+
+```ruby
+require "unicode/display_width/string_ext"
+```
+
+You could also change your `Gemfile` line to achieve this:
+
+```ruby
+gem "unicode-display_width", require: "unicode/display_width/string_ext"

 ## Version 2.4.2 — Performance Updates
 
 **If you use this gem, you should really upgrade to 2.4.2 or newer. It's often 100x faster, sometimes even 1000x and more!**
 
 This is possible because the gem now detects if you use very basic (and common) characters, like ASCII characters. Furthermore, the charachter width lookup code has been optimized, so even when full-width characters are involved, the gem is much faster now.

 ## Introduction to Character Widths
 
 Guessing the correct space a character will consume on terminals is not easy. There is no single standard. Most implementations combine data from [East Asian Width](https://www.unicode.org/reports/tr11/), some [General Categories](https://en.wikipedia.org/wiki/Unicode_character_property#General_Category), and hand-picked adjustments.
