This particular commit has been a long time coming. For reference,
!avatar(email) was an undocumented syntax that simply rendered an
inline 50px avatar for a user in a message, essentially allowing
you to create a user pill like:
`!avatar(alice@example.com) Alice: hey!`

Reimplementation
If we decide to reimplement this or a similar feature in the future,
we could use something like `<avatar:userid>` syntax which is more
in line with creating links in markdown. Even then, it would not be
a good idea to add this instead of supporting inline images directly.
Since any usecases of such a syntax are in automation, we do not need
to make it userfriendly and something like the following is a better
implementation that doesn't need a custom syntax:
` Alice: hey!`

History
We initially added this syntax back in 2012 and it was 'deprecated'
from the get go. Here's what the original commit had to say about
the new syntax:
> We'll use this internally for the commit bot. We might eventually
> disable it for external users.
We eventually did start using this for our github integrations in 2013
but since then, those integrations have been neglected in favor of
our GitHub webhooks which do not use this syntax.
When we copied `!gravatar` to add the `!avatar` syntax, we also noted
that we want to deprecate the `!gravatar` syntax entirely - in 2013!
Since then, we haven't advertised either of these syntaxes anywhere
in our docs, and the only two places where this syntax remains is
our game bots that could easily do without these, and the git commit
integration that we have deprecated anyway.
We do not have any evidence of someone asking about this syntax on
chat.zulip.org when developing an integration and rightfully so- only
the people who work on Zulip (and specifically, markdown) are likely
to stumble upon it and try it out.
This is also the only peice of code due to which we had to look up
emails -> userid mapping in our backend markdown. By removing this,
we entirely remove the backend markdown's dependency on user emails
to render messages.

Previously, we had implemented:
<span class="timestamp" data-timestamp="unix time">Original text</span>
The new syntax is:
<time timestamp="ISO 8601 string">Original text</time>
<span class="timestamp-error">Invalid time format: Original text</span>
Since python and JS interpretations of the ISO format are very
slightly different, we force both of them to drop milliseconds
and use 'Z' instead of '+00:00' to represent that the string is
in UTC. The resultant strings look like: 2011-04-11T10:20:30Z.
Fixes#15431.
This adds support for a "spoiler" syntax in Zulip's markdown, which
can be used to hide content that one doesn't want to be immediately
visible without a click.
We use our own spoiler block syntax inspired by Zulip's existing quote
and math block markdown extensions, rather than requiring a token on
every line, as is present in some other markdown spoiler
implementations.
Fixes#5802.

This code generates the timestamp string to be shown to the user
from the given timestamp in unix format using moment.js.
We also render the timestamp in a pill.
New colors are introduced in msg edit history modal for better readability
These color will have better constrat with their background colors
Fixes#13622
We've often gotten the complaint that Zulip's emoji are a bit too big;
this should address the worst consequences of that (line-wrapping
being off with large emoji present) while still making it possible to
easily see what a given emoji is.
The right place to change this is in rendered_markdown.scss, not the
main emoji definition in zulip.scss, as the latter is also used in
places like the emoji picker where a larger size is valuable.
Closes#12731, an older PR that did this with slightly different
parameters (and without a comment).
Commit ba66dfe977 incorrectly inflated
the specificity level of these rules by moving them inside
.rendered_markdown “entirely for readability”. KaTeX has its own
rules that work better, so just delete ours.

This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.
On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.
Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.
Fixes#12822.
Many of them are now automatically generated by autoprefixer, while
others are unnecessary based on .browserslistrc, and some were just
wrong (the linear-gradient based checkerboard pattern in lightbox has
been broken in Firefox for a while).

Our implementation requires at least 1 space after the
'#' not not break existing linkifiers like '#123', etc.
that generally follow the convention we show in linkifier
examples.
- [valid] : # Hello
- [valid] : # Hello
- [invalid]: #Hello
For the frontend, we have taken the code from v0.7.0 of
upstream marked and made minor changes to avoid having
to refactor a significant part of our marked code.
For the backend, we merely have to change the regex to
force require spaces after #, and add hashheader to our
list of blockparsers.
Fixes#11418.
This moves our main CSS for rendered Zulip message content into an
external file, which may be reusable but in any case should make it
easier to find this content.
