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:
GA Release OCP4.12.2-en-3-20231030
Third production release of the DO180 course for OCP4.12
- feat(title): change course title, close #1468 (#1595)
- feat(prereqs): add DO080 to prereqs (#1661) (#1665)
ch01 (intro):
- rewrite first and third lectures (#1586)
- move some content from ch03 pods to ch01 intro
- rearrange the lectures so it's "arch" (general k8s), then "editions" (OpenShift content), then the rest (web console, etc.)
This also fixes https://issues.redhat.com/browse/PTL-3728 / DO180-588
ch02 (cli):
- feat: changed the output to be retrieved on step 6.2 of resources GE
- feat: added new questions to review quiz
- feat: added content of Go templates in resources lecture, rephrase JSONPath
content
ch03 (pods):
- feat: Removed sub steps in containers GE, specify commands on steps,
added extra instructions - feat: add web console instructions to troubleshooting lecture
- feat: add web console instructions to containers lecture
ch04 (deploy):
- feat: removed content to make the GE simpler and less tedious from
services GE, changed example - fix: removed excess use of the --command option in services GE
Removed the --command flag from the command at step 9.1
Changed the entrypoint of the dbinit container to have the expected handling of double quotes on the arguments.
Updated dbinit image and the GE to use version v1
Resolves Jira: PTL-3211
- feat: mention use of the web console in newapp lecture
- feat: updated to include the use of the web console in workloads lecture,
minor fixes - feat: mention use of the web console in routes lecture, minor fixes
- fix: corrected an incorrect IP address in a graphic in services lecture (#1639)
This fix resolves the following JIRA: https://issues.redhat.com/browse/PTL-9818
ch05 (storage):
- feat: removed step 6 and merged steps 9&10 into one of classes GE
- feat: updated stateful lecture to include the use of the web console, minor fixes
- feat: mention the web console in classes lecture
- feat: mention the web console in volumes lecture
- feat: updated configs lecture to include the use of the web console, expand
secret content - feat: updated volumes GE to use GUI in the first half of the GE.
- feat: updated configs GE to include the use of the web console and other tweaks
- fix: removing a bad practice from the volumes GE (#1643)
- fix: reword in volumes GE (#1662) (#1664)
Step 6 of the GE was changed to add the initialization data to the database
via config map instead of the GUI.
ch06 (reliability):
- feat: updated probes lecture to include the use of the web console, other tweaks
- feat: updated scaling lecture to include the use of the web console, other tweaks
- feat: updated limits lecture to include the use of the web console, including
metrics, and some tweaks
Other changes:
- feat(lab-scripts): use new functions to create and delete projects in lab
scripts, should be a bit more robust - fix(grammar): add a couple of by before using (#1583)
- fix(intro): add missing comma in objective (#1584)
- fix(title-case): fix some title case (#1618), (#1619), (#1625), (#1627)
- chore(devspaces): set up Devspaces (#1511)
- chore(link-checker): use caching link checker (#1626)
- fix: fix some wordings and grammar (#1632)
- chore: remove unused content (#1633)
- fix: fix non-html single references (#1635)
- fix(outline): fix some title case in the outline and add hook (#1634)
- fix(grading): do not use add_error_and_stop (#1637)
Some labs used a non existent add_error_and_stop. Reimplemented those bits. Also removed unused code which referenced this function.
Resolves #1636.
- fix(markup): fix minor markup issues (#1648)
Add some missing replaceable and markup some highlight correctly (not as userinput).
Affected lectures pods/containers/ge, pods/images/ge, pods/troubleshooting/ge, pods/review/lab, deploy/service/ge.
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!

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!

@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

@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.
