Ticketticket Created for both bug reports and feature development on the bug tracker. numbers based on trac timeline for the period above.

Code Changes

Build/Test Tools

  • Build/Test Tools: Reset the PHPMailer mock in Tests_Mail::tearDown(). [37307] #36609
  • Tests: Use the same incrementor for all fields belonging to a given text fixture. [37299] #35199
  • Don’t announce PR builds in SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/. People may submit a PR to our travis build repo, we shouldn’t notify slack when that happens. [37268] #36607
  • Tests: Allow override of MULTISITE and SUBDOMAIN_INSTALL constants [37266] #36567

Canonical

  • Use get_the_terms() to verify that a post belongs to the requested %category%. The get_the_terms() wrapper provides cache support, and saves a database hit

Emoji

  • Smilies: Move convert_smilies to happen later in the the_content filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions.

  • Administration: Introduce admin_print_footer_scripts-$hook_suffix", a dynamic version of the admin_print_footer_scripts hook. This is now more consistent with the generic admin_print_scripts and the dynamic admin_print_scripts-$hook_suffix hooksHooks In WordPress theme and development, hooks are functions that can be applied to an action or a Filter in WordPress.
