Silex v0.46.1

Why upgrade?

This release prevents an older Silex installation from blocking silex login
when its authentication directory still has overly broad permissions.

Changes

• The client automatically tightens a legacy storage directory to 0700 when
  it does not contain a registry credential yet.
• It continues to reject symbolic links and any credential found in a
  directory that another local user may have been able to read.

Impact and migration

No manual action is required when the directory does not contain a registry
credential yet. A credential already present under permissive directory modes
remains rejected and must be revoked before signing in again.
