New spells and talent changes
The build adds 4 spells. Spell records are the noisiest family in a client build (every new item effect, aura and NPC ability is one), so the names below are examples and the true count is the number that matters.
For what is still coming in 12.1.5, Blizzard's own Midnight: 12.1.5 PTR Development Notes is the official list; the records above are what the client holds today and can change before the patch goes live.
Computed from build record 10842 (12.1.5.70077) to build record 14508 (12.1.5.70340). Every count on this page is the number of rows that changed between those two records.

What each spell listed above is and who uses it, read from the current game data: school, cast time and duration, the skill line or Adventure Guide boss it belongs to, and its tooltip with amounts left out (they scale with level and gear).
Deeper Daggers Changed in this build: tooltip text. Physical, instant. Current tooltip: “Shadow damage increased by 8%.”
Before and After: Spell Values This Build Changed
Cooldowns, durations, cast times and schools that differ between this build and the one before it, each side read from its own build.
Each World of Warcraft game build is compared field-by-field against the previous build of
the same version line. Added, changed and removed records are read directly from the client
database, not from patch notes. Prices shown are the game's own vendor values, formatted with
live coin denominations; where a value is unknown it is left blank rather than guessed.
Counts are the true totals for the build; where a heading reads "40 of 11,892" the rows
under it are that many examples, and a record the client has not named yet is left out
rather than printed as an id. A removed record is shown by name without a link, because
the entry it pointed at is gone from the client. Every build lands in the
patch news feed the day it is ingested.
