What happened to bokeh serve --dev

Am I remembering this right? This was an option that would automatically reload the page upon changes to the source file?

Nothing happened to it. I just tested it on OSX with current branch-2.3 locally. If you are experiencing a problem or a question, it is always advised to provide specific details up front:

• exactly what you did
• exactly what you saw
• version, platform, OS info

And as appropriate:

• code samples / reproducers
• screenshots

Otherwise there is no way to speculate what is going on for you, specifically.
