Less than a month old, the newborn Alpha is already celebrating by giving a gift back to its users: upgrades! Resource Shelf (and lots of others) report on the upgrades here. Resource Shelf quotes the changes reported on the Wolfram Alpha blog, and I requote them here for convenience:
Additional linguistic forms for many types of data and questions
More comparisons of composite properties (e.g. “US military vs. UK”)
Combined time series plots of different quantities (e.g. “germany gdp vs population”)
More complete handling of government positions (e.g. “chancellor”, etc.)
Updates to country borders for India, China, Slovenia, Croatia, and others
Updates to naming for certain politically sensitive countries and regions
Additional subcountry regions (e.g. “Wales”); many more to come
Additional support for current and past fractional timezones (e.g. “Iran time”)
City-by-city handling of U.S. states with multiple timezones
Updates to certain European currencies (e.g. for “Cyprus” and “Slovakia”)
Some additional historical events; many more to come
Additional probability computations for cards and coins (e.g. “2 or 3 aces”)
Additional output for partitions of integers (e.g. “partitions of 47″)
Implicit handling of geometric figure properties (e.g. “ellipse with area 6 and major axis 2″)
Additional support for Mathematica 3D graphics syntax
Additional support for stock prices with explicit dates
Support for planet-to-planet distances and “nearest planet”, etc.
Extra information when comparing incompatible units (e.g. “ergs vs. newtons”)
Improved linguistic handling for many foods (e.g. “love apple”)
More mountains added, especially in Australia
Support for many less-common given names (e.g. “zebulon”)
More “self-aware” questions answered (e.g. “how old are you”)
More consistent handling of sidebar links to Wikipedia, etc.
