Problem Statement

I understand you want to get new versions of claude-code pushed out as soon as possible, but please can you change the alert in the tui to only appear for a major/minor version update

You've been pushing patch version updates daily (perhaps even multiple times a day?) lately, and seeing this constantly appearing is getting annoying frankly

I have my own cron setup for running brew update && brew upgrade. No other terminal tool does this. Please stop pestering me with a permanent (and bright/clear) _warning_ that I can't dismiss

I did the upgrade yesterday, and you've released 2 patches since then?

claude-code 2.0.47 -> 2.0.49

Proposed Solution

Only show the message for a major/minor version bump

Alternative Solutions

Show the warning only on fresh session. Don't persist it after I start working with claude

Priority

Medium - Would be very helpful
