 * The (minimum) required Julia version has been raised from 1.0 to 1.6. For older Julia versions the 0.27.X release can still be used. ([#1835][github-1835], [#1841][github-1841])
 * ![Enhancement][badge-enhancement] The `ansicolor` keyword to `HTML()` now defaults to true, meaning that executed outputs from `@example`- and `@repl`-blocks are now by default colored (if they emit colored output). ([#1828][github-1828])

 ## Version `v0.27.19`
 
 * ![Enhancement][badge-enhancement] Documenter can now build draft version of HTML documentation by passing `draft=true` to `makedocs`. Draft mode skips potentially expensive parts of the building process and can be useful to get faster feedback when writing documentation. Draft mode currently skips doctests, `@example`-, `@repl`-, `@eval`-, and `@setup`-blocks. Draft mode can be disabled (or enabled) on a per-page basis by setting `Draft = true` in an `@meta` block.
