To upgrade to Hexo v4, change the following line in your package.json,

-  "hexo": "^3.9.0",
+  "hexo": "^4.0.0",

Breaking change

chore: drop Node 6 #3598
fix post_link, asset_link when title contains unescaped html charaters #3704
- Affects asset_link, post_link tag plugins
- If you want to retain unescaped characters, set false to the final argument {% asset_link 'filename 'title' 'false' %}
fix: encode permalink by default #3708
- If you currently use encodeURI(post.permalink) (including permalink of page, tag & category variables), there are three options:
  1. Use encodeURI(decodeURI(post.permalink)) for backward-compatibility with hexo v3.9 (and older)
  2. Use encodeURL() function provided by hexo-util, it is backward-compatible
  3. Drop encodeURI() function, this breaks backward-compatibility
- If you want to use the variables in decoded form,
  - Use decodeURI(post.permalink)
  - decodeURL() of hexo-util can decode punycoded domain.
- This change does not apply to this.url variable.
fix(paginator): add escape option for compatibility with hexo-util 1.3.0 #3728
- Theme devs, if you customize prev_text/next_text with html (e.g. to insert icons), you need to set escape: false in the parameter.

- Support excerpt: in front-matter
switch minimatch to micromatch #3538
- Refer to micromatch docs for advanced globbing

Option to use date instead of file mtime for updated date #3235

feat(list_tags): add Schema “keywords” and Microdata “tag” #3678
feat(permalink_variable): add pretty_urls option to remove index.html from url #3691

pretty_urls:

- Does not apply to this.url variable (see #3661).
- Should be compatible with existing canonical-related plugins, recommend plugin and theme devs to test
