Hi Joan,
Congrats to the new release.
Thanks! Everyone put in a lot of hard work on 3.0.0.
I was excited to see SM60 and ES2015 support but then I read …
These do not have SM60:
...
* Ubuntu 16.04 (xenial), 18.04 (bionic)
* Ubuntu 20.04 (focal) should include SM60 once released in April.
Many users do not upgrade right away to a new OS release for many reasons. E.g.
my stuff is still on 16.04 and I am now looking to eventually move onto 18.04.
I think that adoption of a new OS like the upcoming 20.04 will at first be only
for brand new installs for new software and it will take a while for existing
projects to move to 20.04.
Therefore, is there a plan to maybe have SM60 on 18.04? (I understand why there
is no effort going into 16.04 anymore.)
I'm sympathetic to your situation, but...probably not. Here's my reasoning.
Ubuntu does not provide packages that I'm aware of for SM60 on 18.04.
There are 19.04 packages, but it's our policy to support only LTS
releases. Of course, 20.04 now has the packages.
We're trying to get away from packaging SM ourselves. It's a lot of
effort, and I'm the only one maintaining it, on a volunteer basis. We
had to do so for 1.8.5 because the system-provided packages were broken
for our needs, because we don't like to depend on 3rd party PPAs, and
because distros started dropping the packages out of distros a couple of
years ago. For SM60, it would be going back through all of that effort,
just to package SM60 for 1, maybe 2 distros. I'd really rather not.
You can always use the Docker container. It is wildly popular: since
CouchDB 3.0.0 was released, there's already been more than 2 *million*
downloads of the couchdb image. (By comparison, there's been about 3000
.deb and 750 .rpm 3.0.0 downloads in the same timeframe.) (One weakness
in the stats is we don't know if all of those 2 million downloads were
of the 3.0.0 Docker container, but we do know that the jump in downloads
was a significant increase over downloads in the previous month.)
It _may_ be possible to create a 20.04 chroot inside of 18.04 if the
libc ABI hasn't changed. Finally, anyone can build binaries for CouchDB
and share them. If you decide to do either of these and publish your own
solution, do let the list know!

Great news, congratulations on the release!
Hi Sebastien! Thanks!
Are there more details over what the upgrade of the JS engine means in
practice?
Can we write ES2015 modules and use let/const, arrow functions and the like
for map/reduce functions?
Yes, that's the idea. You can do anything supported by Firefox 60esr.
Sandboxing rules for couchjs still apply. You can also write your map/reduce
functions directly using more modern syntax:
"map": "(function (doc) {emit(doc._id, 1);});"
That should help with module inclusion, declarations, etc. A PR against our
docs to include this info would be most welcome - we overlooked this I think
with the SM60 changes.
The compatibility tables online here should help you know what's achievable:
https://kangax.github.io/compat-table/es6/
Be sure to pick "Show obsolete platforms" to get a column for "FF 60 ESR."
Do remember also that if you have to replicate with older versions of CouchDB,
you'll want to be backward compatible.
Note that only the following binary downloads have SpiderMonkey 60 in them:
* Debian buster packages (.deb)
* x86_64, ppc64le only (not arm64v8)
* CentOS 8 packages (.rpm)
* x86_64 only
* docker (couchdb, apache/couchdb)
* x86_64, ppc64le only (not arm64v8)
* macOS (10.10+, 64-bit)
* Windows (7+, 64-bit)
These do not have SM60:
* CentOS 6, 7 (not expected to be added)
* Debian stretch (not expected to be added)
* Ubuntu 16.04 (xenial), 18.04 (bionic)
* Ubuntu 20.04 (focal) should include SM60 once released in April.

Thanks for creating this version. Good job!!
You're welcome!
As all Ember App's we use need
https://www.npmjs.com/package/ember-cli-deploy-couchdb Will Virtual
hosts
and Rewrite functions (/{db}/{ddoc}/_rewrite) be supported in 3.0 and
removed in 4.0 ?
Yes, exactly. 3.x will retain these, but are flagged as deprecated. The
plan is to remove them entirely with 4.0, along with show and list
functions.
