📢 The package has been migrated to the @xterm scope (#4860, #4861) via @Tyriar. This means that the old xterm and xterm-* packages are now deprecated and will no longer be maintained. This was done mainly for security reasons to remove ambiguity around the package names and to prevent potential typosquatting attacks.
Please use the new scoped @xterm/* packages.
