Version 4.12.2 versus 4.12 of DO180 course?

[DRobitaille]

I just noticed that there is now a version 4.12.2 of the DO180.  Currently without any new updated videos.  Do we have access to some sort of changelog to judge how different the new version is compared to 4.12. 

I'm currently in the process of reviewing the content of DO180/DO280 in preparation for my upcoming EX280 exam (based on "4.12"), so I'm wondering if it's worth studying  the 4.12.2 version instead of 4.12.

Hi there! Videos and translations updates are currently in progress for 4.12.2. Once those are completed, the 4.12 version of the course will roll off the catalog. We pushed this release as a new version to prevent progress tracking issues that occur when overwriting an existing course.

In this release, we focused on implementing instructor feedback, improving the CH01 content, and featuring the OpenShift web console more throughout the lectures and some GEs. We also experimented with creating a changelog for this release. Below are the details for this release:

• chore(gh): add graphic request issue template from DO457 (#1611)

• fix(userinput): fix password prompts (#1649)

To match the rest of the course, the password should be shown as userinput.

Removed replaceable that probably tried to indicate that the typing is hidden.

pods/images/ge, pods/troubleshooting/ge, updates/ids/ge

Either the 4.12 or 4.12.2 version of the course will be sufficient for EX280, but I do recommend taking 4.12.2 because of the improvements and updated graphics that were implemented from instructor and student feedback. I hope this helps!

Thank you,

Hey @Natalie_Lind ! Many thanks for this resourceful update. I am sure we all will greatly benefit from it.

There is video content associated with this course? Could someone please share a link or explain how to navigate to the videos from the course menu?

[Chetan_Tiwary_]

Thanks for reaching out!

Yes, the video course is there for DO180v4.12  ( embedded in the course in ROL portal - if you are a ROL subscriber ) 

Video course for v4.12.2 is in progress and not available as of now. It will be available soon as per above update.

Hello @Natalie_Lind,
Is there a way I can access the course material in a PDF file for my offline reading and preparing - so I can take notes offline? Is this something you can help me with?

Forward thanking you!

[Wasim_Raja]

@pvrb If you have an RHLS subscription then there should be an option to download the pdf once you open the course something like below:

Incase you are using a partner based subscription you can reach out to the partner or raise a support case for any help.

Regards,

Wasim

[Chetan_Tiwary_]

@pvrb Yes you can download the course in a PDF file for offline consumption - provided you have a valid required subscription type. 

Since you are not able to see the pdf download option - I believe you are having a partner based open subscription. You need to have RHLS subscption to get the same.

@Wasim_Raja Gratefully thank you and I believe mine is partner based subscription and when I raised a support case - I was told to get to RHLS subscription.

In any case you answered my question. THANK YOU!

@pvrb Welcome!!
