You are right that most VE installs won't actually be able to upgrade to
this newer version of Parsoid if they are running LTS versions of MW
(which probably most installations are -- looks like only a few hundred
installs are based on MW 1.31 and later according to
)
MW 1.31 LTS is likely going to be out in May, and so at that time, you
will be able to upgrade.
But, releasing 0.9.0 now lets us break node v4 compatibility in our
codebase.

Heiya,
I apprechiate this e-mail informing about breaking changes.
So basically everybody still on MW 1.27 LTS, 1.29 and 1.30 will have to
hold parsoid updates since I do not assume that VE of December 12, 2017
will run on MW 1.27.x, etc.
I just hope that VE for MW 1.31 LTS will not have a hard requirement on
parsoid 0.9.0 because then things will get painful. Does not sound like
it though but one never knows.
Cheers Karsten

Hello everyone,
We are releasing the next version of the Parsoid deb and npm packages
(v0.9.0) later today. There is one significant change in this release
that might affect some VisualEditor installations. This version of
Parsoid wraps sections in <section> tags and bumps the HTML version to
1.6.1. However, VisualEditor installations older than Dec 12, 2017 are
not compatible with this section wrapped output.
In order to prevent silent failures, Parsoid will do a hard fail and
reject parse requests with a HTTP 406 when it receives a version
string smaller than 1.6.0 (which VE before Dec 12, 2017 would issue).
VE will then popup the following error: "Error loading data from
server: apierror-visualeditor-docserver-http: HTTP 406. Would you like
to retry?" Retries won't help in this scenario.
Knowing this, you have a couple of options:
* Not upgrade Parsoid. If you upgrade Parsoid without reading this
notice and later stumble on this (which we'll also add to the
Parsoid releases page), you have the option of downgrading your
Parsoid install by downloading an older deb package from
https://people.wikimedia.org/~ssastry/parsoid/debs/
* If you choose to upgrade Parsoid and your VE installation is from
before Dec 12, 2017 (which is probably most of you), the recommended
solution is to upgrade your VisualEditor installation as well.
If for some reason you really really need to upgrade Parsoid but
cannot upgrade VisualEditor, contact us on IRC in #mediawiki-parsoid
to ask us how you can do that.
