Other. It never meant anything. For instance, so-called Classical Liberals held a huge range of incompatible beliefs:

• JS Mill wanted the State to "liberate" individuals from the "restrictions" of society/religion/etc
• Garibaldi was a veritable authoritarian
• Hayek was a democratic socialist who favored the social/welfare programs we have in every nation-state today
• John Locke formalized social contract theory, which helped to expand the power of the State to new levels
• Mises and Bastiat were both minarchists

Just like Classical Liberalism, modern Liberalism means nothing, because it is applied to people with radically different beliefs.
