q

2.0.17 and 2.0.18 haven't been officially released, so this release contains both of their deliveries:

From 2.0.17:
Multiple usability additions and fixes

• Fixed multiline quoting issue with -W minimal
• Added -p/-P convenience flags for pipe-delimited files
• Added -L flag to list all user functions
• Added warning when -p/-t is used along with -d, or -P/-T along with -D
• Generalized sha() user function to provide other algorithms (old sha1() remains for backward compat)
• Added md5() user function
• md5 and sha both require encoding to be provided. Will be automated in the future
• Added sqrt() and power() user functions
• Added stdev_sample() and stdev_pop() user functions

From 2.0.18:

• q benchmark logic and results

Please download release 2.0.9 from the web site http://harelba.github.io/q/ which contains rpm and deb packages as well. Another option would be to download version 2.0.9 from the "releases" list here, but it doesn't contain any rpm or deb packaging, just the windows installation.

This release has one feature - Being able to write the data into an sqlite3 disk database.

Use -S <db-filename> in order to save the data, and use any sqlite3 client to analyze/process it.

This is the first actual release of 1.6.x (previous 1.6.x were used to test the new release process).
