Changes

1.1.4 – April 2026

1.1.3

Deprecate the Data.Text.Prettyprint.* modules
- Users should migrate to the new Prettyprinter module hierarchy.
- The old modules will be removed no sooner than September 2022.

1.1.2

Add shallower Prettyprinter module hierarchy exposing the same API.
- The current plan for the existing Data.Text.Prettyprint.Doc* modules is:
  - Start deprecation in early 2021.
  - Remove the modules after a deprecation period of at least one year.
Make renderLazy lazy, and speed it up.
Add export list for Prettyprinter.Render.Terminal.Internal.
Optimize generating spaces for indentation.
Enable -O2.
Extend GHC support to 7.6 and 7.4.

1.1.1.2

Fix documentation claiming there would be a trailing newline in renderIO when there is none

1.1.1.1

renderIO now renders directly to STDOUT, instead of first building a textual rendering and then printing that to STDOUT.

1.1.1

Expose AnsiStyle’s constructors for adaptability

1.1

Overhauled the API significantly – Styles are now combined using the Semigroup instance from a number of readable primitives.

1.0.1

Fix version shenanigans, since the prerelease was released to Hackage as version 1 already, so uploading the »new« version 1 did not work
