I made the mistake of upgrading a working IDE 2.0 platform to the latest rev today and now some of my processors (8266) no longer upload.
What are my options?
Can I revert to the previous version? This would be a wonder feature in the event
problems are encountered.
Can I delete the IDE and get the previous version?
Or just go back to 1.8.19?
edit;
I am confused as all get out now. After doing the new upgrade to the IDE when I check the Help About Arduino & it says 2.0.4 date 2023-02-27.
Now whenever I invoke the IDE a screen comes up saying Update Available.
Scroll down until you find the version you want to download.
At the bottom of the entry for that release, you'll see an "Assets" section. This is an expandable section of the page, so if it is collapsed, click on it to expand:
Click the appropriate download link from the list under the "Assets" section.
For example, if you are using Windows, you could click the "arduino-ide_2.0.4_Windows_64bit.zip" link for the ZIP package of Arduino IDE 2.0.4:
So what happened?
I went through the upgrade process and everything went without a hitch after it downloaded the upgrade files and I was prompted thru the install. I also rebooted.
