LATEST - unicorn-5.4.1 Documentation

### unicorn 5.4.0 / 2017-12-23 23:33 UTC¶ ↑

    Rack hijack support improves as the app code can capture and use
    the Rack `env' privately without copying it (to avoid clobbering
    by another client).  Thanks to Sam Saffron for reporting and
    testing this new feature:

    We also now support $DEBUG being set by the Rack app (instead of
    relying on the "-d" CLI switch).  Thanks to James P Robinson Jr
    for reporting this bug:
      https://bogomips.org/unicorn-public/D6324CB4.7BC3E%25james.robinson3@cigna.com/T/
      (Coincidentally, this fix will be irrelevant for Ruby 2.5
       which requires 'pp' by default)

    There's a few minor test cleanups and documentation updates, too.

    All commits since v5.3.1 (2017-10-03):

        reduce method calls with String#start_with?
        require 'pp' if $DEBUG is set by Rack app
        avoid reusing env on hijack
        tests: cleanup some unused variable warnings
        ISSUES: add a note about Debian BTS interopability
