-------------------------
In the previous version, Google used the "family: man, woman, boy" emoji to 
represent the generic "family" emoji. In this version, Google created a unique 
emoji to represent the "family" emoji. The justification is that all 3 people 
in the new emoji are now represented as gender-neutral.

Emoji #408 is the family emoji. Emoji #409 is "family: man, woman, boy".

Or compare https://emojipedia.org/family/ with 
https://emojipedia.org/family-man-woman-boy/
If you click Google, you can see the historical versions. This update is 
Android 9.0; the version currently in 18.04 LTS is Android 8.0.

The same thing happened with the "couple with heart" emoji, #404 and #405 where 
the 2 adults now are gender-neutral.

So yes, this is a behavior change, but it is expected that there are
some changes to existing emoji. For a more dramatic example, see LP:
#1766736 (the pistol emoji change which landed in Ubuntu 18.04 LTS just
before release).

Not to mention the dramatic style change in Android 7.0. See
https://blog.emojipedia.org/rip-blobs-google-redesigns-emojis/

Small glyphs
------------
The small glyphs change was made in this commit:
https://github.com/googlei18n/noto-emoji/commit/e571d53e0299bd1

The commit message says that "android has legacy tooling that expects
small metrics" but they'll eventually switch to using big metrics. But
on closer reading, it does look like this used to build big metrics
before this change, so let me ask for clarification.

Title:
  Update fonts-noto-color-emoji to 20180810 release for Unicode 11

Status in fonts-noto-color-emoji package in Ubuntu:
  Fix Released
Status in fonts-noto-color-emoji source package in Bionic:
  Incomplete

Bug description:
  Impact
  ======
  Google has released the latest version of their color emoji font that is 
shipped with Android 9 "Pie".
  The new release is a major upgrade, including support for the new Unicode 11 
standard. Some existing emoji were tweaked.

  We need this update in Ubuntu 18.04 LTS so that the new emoji work.

  https://blog.emojipedia.org/whats-new-in-unicode-11-0/
  https://blog.emojipedia.org/inclusive-emojis-coming-back-to-android/
  https://emojipedia.org/emoji-11.0/

  Note that several of the new combined emoji (like red-haired man 👨‍🦰 )
  will need an update elsewhere (pango?) to display as combined.

  Test Case
  =========
  1. After installing the update, visit
  https://unicode.org/emoji/charts/full-emoji-list.html
  The browser column should match the Google column

  2. You can also use the Characters app shipped by default to verify
  that the emoji seem to work ok.

  Regression Potential
  ====================
  Except for being rebuilt from source in Ubuntu, this is basically the same 
emoji font Google ships in the latest Android.

  We can easily verify that the update is successful by completing the 2
  test cases above.

  Other Info
  ==========
  Google does a major update of this font once per year corresponding with the 
annual release of the new Unicode standard and Android.

  Proposed pango update:
  https://gitlab.gnome.org/GNOME/pango/merge_requests/15

  gtk3 could then probably use an update to get the new emoji in its
  emoji chooser.

  Most other GNOME distros (including Debian Testing and Fedora 28) also
  use this font as their default color emoji font.
