Grunt Newer Versions Save

• Write current time to timestamp file (thanks @malys, see #69)

This release doesn't include any API breaking changes, so upgrades should be trouble free. All the rest of the 1.x releases will remain backwards compatible.

• Document that grunt-newer works with grunt-spritesmith >= 3.1.0 (thanks @danez, see #66)
• Support for an empty list of source files (thanks @ruslansagitov, see #62)

• Support for a single source file that matches the dest file (thanks @btholt, see #42 and #62)
• Avoid unhandled error when task is aliased (see #61)

• Support for override option. In cases where a src file should be included even if it has not been modified (e.g. a LESS file whose imports have been modified), the override option can be used (see #35)

• When src and dest files are the same, the previous run time is considered (see #24)

• Compare src file modification times to dest files if present (see #2)

• Filter out file objects with no remaining src files (see #6)

• Fix use of any-newer on task with multiple targets (thanks @royriojas, see #7)

• Add newer-reconfigure to properly reset task configuration (see #8)

• Correctly handle cases where dest file is not present (thanks @royriojas, see #11)
