Migration to v5 ​

v5 has the same external API as v4, only internals were changed. Some external plugins may need update (all plugins from markdown-it github organization are up to date).

For users ​

External API did not change.

• If you use markdown-it with plugins, make sure to update them.

For plugin developers ​

• added stateBlock.sCount to calculate indents instead of stateBlock.tShift, it only differs if tabs are present:
  • stateBlock.tShift is used to calculate a number of characters (tab is 1 character)
  • stateBlock.sCount is used to calculate the block offset (tab is 1-4 characters depending on position)
• added stateInline.ruler2 and stateInline.delimiters needed to parse emphasis-like markup better
  • emphasis-like tags now can't be skipped with stateInline.skipToken, they treat a sequence of markers (e.g. ***) as a token instead
  • stateInline.delimiters is linked with stateInline.tokens, so truncating/splicing stateInline.tokens may break things
