Roadmap

Pandoc doesn't have a strict roadmap but this page should serve as an overview about major changes to pandoc that are on our radar.

AST changes

restructuring readers and writers in typeclasses so that they can be run consistently in either pure or in IO, see jgms's explanation, also issue 2930
Attributes for all elements
changing String to Text everywhere
changing JSON serialization format to be more human-readable, less Haskell-ADT-oriented, see this comment
a Figure block element, capable of containing multiple images
internal links/references to tables and figures
PageBreak element
replace Strikeout element with a Deleted element; add an Inserted element
colspans in tables (and possibly also rowspan)
change Format from String to a sum type
