This feature introduces the concept of themes. Themes are an evolution
of site customizations.
Themes introduce two very big conceptual changes:
- A theme may include other "child themes", children can include grand
children and so on.
- A theme may specify a color scheme
The change does away with the idea of "enabled" color schemes.
It also adds a bunch of big niceties like
- You can source a theme from a git repo
- History for themes is much improved
- You can only have a single enabled theme. Themes can be selected by
users, if you opt for it.
On a technical level this change comes with a whole bunch of goodies
- All CSS is now compiled using a custom pipeline that uses libsass
see /lib/stylesheet
- There is a single pipeline for css compilation (in the past we used
one for customizations and another one for the rest of the app
- The stylesheet pipeline is now divorced of sprockets, there is no
reliance on sprockets for CSS bundling
- CSS is generated with source maps everywhere (including themes) this
makes debugging much easier
- Our "live reloader" is smarter and avoid a flash of unstyled content
we run a file watcher in "puma" in dev so you no longer need to run
rake autospec to watch for CSS changes
This lets an SMTP server optionally decide if it should reject a mail without
passing it on to Discourse at all, possibly before even reading the
email's payload, to prevent spam-induced backscatter and save resources.
This just does the bare minimum sanity checking that could prevent obvious
backscatter. For legit errors from legit users, Discourse will still send a
much more pleasant reply email.
This allows users who entered a typo or invalid email address when
signing up an opportunity to fix it and resending the confirmation
email to that address.
* `1.month.ago + 1.month` uses the calendar month for calculations
such that `1.month.ago` from the 30th of March 2017 will give
us the 28th of February 2017. Adding one month ahead from
28th February 2017 will be 28th of March 2017.
This is to fix the problem where a newly created user would not
receive live updates for the first notification if the notification
is published before the client has subscribed to the channel.
