1
00:00:00,630 --> 00:00:06,870
In this section, I'm going to show you how to upgrade your node, a red instance from version one to

2
00:00:06,870 --> 00:00:08,460
version 2.1.

3
00:00:08,940 --> 00:00:18,000
As you can see here in the release plan, version 2.1 was released sometime in the end of 2021, around

4
00:00:18,000 --> 00:00:19,320
October and November.

5
00:00:19,890 --> 00:00:27,420
And version 2.2 is still upcoming, but not released yet expected sometime in the first quarter of 2022.

6
00:00:28,080 --> 00:00:35,850
When I created this course, the vision back then for node rate was 1.1.1.

7
00:00:36,360 --> 00:00:41,610
So at this point in time, I'll be showing you how to upgrade your instance.

8
00:00:42,150 --> 00:00:45,990
In my case, it's going to be from version 1.1.1.

9
00:00:46,350 --> 00:00:52,030
Yours is probably going to be our more recent version, depending on when you are taking this course.

10
00:00:52,530 --> 00:01:00,480
But in any case, regardless of which version your instance of Node read is at the moment, the upgrade

11
00:01:00,480 --> 00:01:01,980
process will be the same.

12
00:01:02,420 --> 00:01:08,370
And before we get into the details, I just wanted to show you where you can find information about

13
00:01:08,370 --> 00:01:13,240
what are the changes in version 2.0 and the current version 2.1.

14
00:01:13,290 --> 00:01:17,250
You can see 2.1 released October two, 2021.

15
00:01:17,790 --> 00:01:22,170
So I'm looking at the Node Red Blog and let's have a look at version 2.0.

16
00:01:22,890 --> 00:01:33,330
The most important change in version 2.0 is the support or more recent version of the node change runtime

17
00:01:33,330 --> 00:01:34,200
environment.

18
00:01:34,620 --> 00:01:39,810
So no trade 2.0 does not support anything earlier than Node.

19
00:01:39,960 --> 00:01:50,280
JS 12.17 I think that there's quite a lot of new features and changes both in the front end and under

20
00:01:50,280 --> 00:01:50,700
the hood.

21
00:01:51,240 --> 00:01:59,220
So one important new feature that you find is a new command that allows you to basically go through

22
00:01:59,220 --> 00:02:00,420
a wizard.

23
00:02:01,080 --> 00:02:07,080
You answer a few questions and then the wizard will provide you with a configuration settings file,

24
00:02:07,470 --> 00:02:11,430
which you're not going to have to go and edit manually.

25
00:02:11,430 --> 00:02:17,970
So you can just follow these the, the questions of the wizard and you'll have a configuration file

26
00:02:17,970 --> 00:02:19,230
created for you.

27
00:02:19,740 --> 00:02:26,940
There's a lot of other changes, such as a restructured default settings file as defaults flows file

28
00:02:26,940 --> 00:02:36,870
name a new editor for the front end looks like this and the completion and more interesting color scheme

29
00:02:36,870 --> 00:02:38,910
which is configurable via CCIS.

30
00:02:39,420 --> 00:02:46,620
That of course changes and additions to nodes or changes to existing nodes, but also a new node to

31
00:02:46,680 --> 00:02:47,460
have been added.

32
00:02:48,030 --> 00:02:53,880
And at this point, I'm not going to go through the details and just showing you where this information

33
00:02:53,880 --> 00:02:56,520
exists so you can go through it if you want to.

34
00:02:57,060 --> 00:03:08,550
But once we do the upgrade to Node read version 2.1, I'm going to include new lectures in this section

35
00:03:08,550 --> 00:03:15,690
where I'm going to take you through some of the most important or interesting new features in Node great

36
00:03:15,840 --> 00:03:17,970
version two and 2.1.

37
00:03:18,510 --> 00:03:25,680
And speaking of version 2.1, here is a blog post which contains information about what's new mostly

38
00:03:25,680 --> 00:03:26,910
in version 2.1.

39
00:03:26,910 --> 00:03:28,740
The changes are in the front end.

40
00:03:29,130 --> 00:03:30,060
So for example.

41
00:03:31,080 --> 00:03:33,780
It is a to go to the beginning as soon as you do the upgrade.

42
00:03:33,810 --> 00:03:35,520
You will see it in the next lecture.

43
00:03:35,970 --> 00:03:39,390
It's a possible now to hide tabs.

44
00:03:39,720 --> 00:03:47,190
If you have a busy project space with a lot of tabs, you can hide those that you don't want to see

45
00:03:47,550 --> 00:03:50,160
and de-clutter your working environment.

46
00:03:50,850 --> 00:03:58,590
So now dynamic and kitty modes and so on, you can see all of those changes that new nodes such as said

47
00:03:58,590 --> 00:04:05,970
link coal node allows you to create interactions between tabs between flows.

48
00:04:06,980 --> 00:04:09,980
And create subroutine like flows.

49
00:04:10,190 --> 00:04:17,960
I'm going to demonstrate those new features in later lectures in this section of the course.

50
00:04:18,860 --> 00:04:25,580
So let's go ahead into the next lecture where I'll show you how to upgrade node rate from version one

51
00:04:25,670 --> 00:04:27,440
to version 2.1.
