+# 0.4.0.0
+
+* Dropped `text-show` entirely; now `show` works via `Prelude.show`, which is
+  slower but avoids a heavy dependency. It is recommended to use
+  `text-format`, `formatting` or `fmt` if fast formatting is needed.
+  
+* Added `show` and `format` to `Data.Text.Lazy.All`.
+
 # 0.3.1.0
 
-* Bumped the text-show upper bound. (text-show added some instances.)

 {- $showing
 
-'show' is a fast variant of @show@ for 'Text' \/ 'Builder' that only works for some types – it's very fast for 'Int', etc, but doesn't work for types that you have defined yourself. (If you want more instances, import <https://hackage.haskell.org/package/text-show-instances text-show-instances>.)
-
-'show'' is a shortcut for @pack.show@ that works for everything with a 'Show' instance but is slower.
+Variants below use 'P.show' from "Prelude". If you want faster showing,
+either use <https://hackage.haskell.org/package/text-show text-show> or some
+formatting library.
