In this section, I'm going to show you how to upgrade your node, a red instance from version one to
version 2.1.
As you can see here in the release plan, version 2.1 was released sometime in the end of 2021, around
October and November.
And version 2.2 is still upcoming, but not released yet expected sometime in the first quarter of 2022.
When I created this course, the vision back then for node rate was 1.1.1.
So at this point in time, I'll be showing you how to upgrade your instance.
In my case, it's going to be from version 1.1.1.
Yours is probably going to be our more recent version, depending on when you are taking this course.
But in any case, regardless of which version your instance of Node read is at the moment, the upgrade
process will be the same.
And before we get into the details, I just wanted to show you where you can find information about
what are the changes in version 2.0 and the current version 2.1.
You can see 2.1 released October two, 2021.
So I'm looking at the Node Red Blog and let's have a look at version 2.0.
The most important change in version 2.0 is the support or more recent version of the node change runtime
environment.
So no trade 2.0 does not support anything earlier than Node.
JS 12.17 I think that there's quite a lot of new features and changes both in the front end and under
the hood.
So one important new feature that you find is a new command that allows you to basically go through
a wizard.
You answer a few questions and then the wizard will provide you with a configuration settings file,
which you're not going to have to go and edit manually.
So you can just follow these the, the questions of the wizard and you'll have a configuration file
created for you.
There's a lot of other changes, such as a restructured default settings file as defaults flows file
name a new editor for the front end looks like this and the completion and more interesting color scheme
which is configurable via CCIS.
That of course changes and additions to nodes or changes to existing nodes, but also a new node to
have been added.
And at this point, I'm not going to go through the details and just showing you where this information
exists so you can go through it if you want to.
But once we do the upgrade to Node read version 2.1, I'm going to include new lectures in this section
where I'm going to take you through some of the most important or interesting new features in Node great
version two and 2.1.
And speaking of version 2.1, here is a blog post which contains information about what's new mostly
in version 2.1.
The changes are in the front end.
So for example.
It is a to go to the beginning as soon as you do the upgrade.
You will see it in the next lecture.
It's a possible now to hide tabs.
If you have a busy project space with a lot of tabs, you can hide those that you don't want to see
and de-clutter your working environment.
So now dynamic and kitty modes and so on, you can see all of those changes that new nodes such as said
link coal node allows you to create interactions between tabs between flows.
And create subroutine like flows.
I'm going to demonstrate those new features in later lectures in this section of the course.
So let's go ahead into the next lecture where I'll show you how to upgrade node rate from version one
to version 2.1.
