Problem Statement

Installed claude about 2 weeks ago: issue #14980 is still present.
What's the suggested solution? Do we need to manually clear older versions?

max@pc:~$ ls -l .local/share/claude/versions/
totale 754844
-rwxr-xr-x 1 max max 256535352 lug  8 11:28 2.1.204
-rwxr-xr-x 1 max max 257006392 lug  8 23:29 2.1.205
-rwxr-xr-x 1 max max 259402552 lug 13 00:10 2.1.207

Proposed Solution

After installed a new version, can the previous versions can be deleted, maybe asking the user.

Alternative Solutions

Alternatively, a CLI command like claude cleanup (or meybe in the TUI) to perform the same operation on-demand.
