    Hi,

    I'm glad to announce a new release of NGINX Unit.

    -------------------------------------------------------------------
    To all Unit package maintainers: please don't miss the new '--tmp'
    configure option. It specifies the directory where the Unit daemon
    stores temporary files (i.e. large request bodies) at runtime.
    -------------------------------------------------------------------

    In this release, we continue improving the functionality related to
    proxying and static media asset handling.

    Now, the new 'upstreams' object enables creating server groups
    for weighted round-robin load balancing:

    {
    "listeners": {
    "*:80": {
    "pass": "upstreams/rr-lb"
    }
    },

    "upstreams": {
    "rr-lb": {
    "servers": {
    "192.168.0.100:8080": { },
    "192.168.0.101:8080": {
    "weight": 2
    }
    }
    }
    }
    }


    See the docs for details:

    - https://unit.nginx.org/configuration/#configuration-upstreams

    So far, it's rather basic, but many more proxying and load-balancing
    features are planned for future releases.

    By its design, the new 'fallback' option is somewhat similar to the
    'try_files' directive in nginx. It allows proceeding to another
    action if a file isn't available:

    {
    "share": "/data/www/",

    "fallback": {
    "pass": "applications/php"
    }
    }


    In the example above, an attempt is made first to serve a request
    with a file from the "/data/www/" directory. If there's no such
    file, the request is passed to the "php" application.

    Also, you can chain such fallback actions:

    {
    "share": "/data/www/",

    "fallback": {
    "share": "/data/cache/",

    "fallback": {
    "proxy": "http://127.0.0.1:9000"
    }
    }
    }


    More info:

    - https://unit.nginx.org/configuration/#configuration-fallback

    Finally, configurations you upload can use line (//) and block (/* */)
    comments. Now, Unit doesn't complain; instead, it strips them from the
    JSON payload. This comes in handy if you store your configuration in a
    file and edit it manually.


    Changes with Unit 1.16.0 12 Mar 2020

    *) Feature: basic load-balancing support with round-robin.

    *) Feature: a "fallback" option that performs an alternative action if a
    request can't be served from the "share" directory.

    *) Feature: reduced memory consumption by dumping large request bodies
    to disk.

    *) Feature: stripping UTF-8 BOM and JavaScript-style comments from
    uploaded JSON.

    *) Bugfix: negative address matching in router might work improperly in
    combination with non-negative patterns.

    *) Bugfix: Java Spring applications failed to run; the bug had appeared
    in 1.10.0.

    *) Bugfix: PHP 7.4 was broken if it was built with thread safety
    enabled.

    *) Bugfix: compatibility issues with some Python applications.


    To keep the finger on the pulse, see our further plans in the roadmap here:

    - https://github.com/orgs/nginx/projects/1

    Also, good news for macOS users! Now, there's a Homebrew tap for Unit:

    Stay healthy!
