0.4.0

• Unused values(e.g. local a = expr1; ... a = expr2) are now detected;
• In CLI, rockspecs(arguments ending with .rockspec) now expand into list of related .lua files;
• Unused varargs are now detected;
• Some minor fixes and CLI improvements.

0.3.0

• luacheck is now _ENV-aware: "globals" inside chunks with custom _ENV are ignored, but their presence marks the _ENV variable as used; accessing the outermost("default") _ENV is permitted, too.
• In --globals option of the CLI hyphen now expands to all standard global variables;
• New -c/--compat flag defines some additional globals for Lua 5.1/5.2 compatibility(e.g. setfenv).
• New -l/--limit option allows setting a limit of warnings. If the limit is not exceeded, the CLI exits with 0.
• The -q/--quiet flag now can be used several times(-q/-qq/-qqq) to make the CLI more or less quiet.
• Other small improvements.

0.2.0

• Command-line interface now prints per-file reports as they are produced instead of waiting for all files to be checked;
• luacheck now recognizes different types of variables(usual locals, function arguments and loop variables) and reports them accordingly;
• luacheck now distinguishes accessing global variables from setting them;
• In command-line interface -q switch makes luacheck only print total number of warnings instead of suppressing output completely.
