v0.31.1

New Stuff

• nvm uninstall: Check installation dir permissions before uninstalling; display "fix" commands (#847)
• nvm alias: colorize output to match nvm ls
• nvm alias: colorize output when creating aliases
• nvm ls/nvm alias/nvm ls-remote: only colorize when colors are supported

Fixes

• don’t use bash == in conditionals
• nvm run: pass through --silent on bare nvm run
• nvm exec: show “io.js” for io.js versions
• set -e: ensure nvm_version returning 3, and nvm_alias returning 2, doesn’t terminate the process
• nvm alias: explicitly forbid user aliases in subdirs
• read exits 1 when .nvmrc lacks a trailing newline; avoid that
• set -x: avoid an unbound variable
• deactivate: unset $NVM_BIN and $NVM_PATH (#1033)

Performance

• nvm alias: slightly speed up alias resolution
• Use awk to improve version comparison performance

Robustness

• add a missing command to a sed call

Misc

• Various README tweaks
• Various testing improvements
• Prefer nvm --help over nvm help
