Hello,

I’m very happy to let you know that Zato 1.1 has just been released.

What is Zato

Zato is a lightweight, yet complete, ESB (Enterprise Service Bus) and
app server in Python designed for creating middleware applications and
systems of systems.

Zato is open-source software released under a commercial-friendly LGPL
license.

Release notes

This release is based on feedback from early adopters and includes a
number of improvements to help first time users get started more easily.

An important addition in 1.1 is a unified installer for OS X, Ubuntu,
Mint and Fedora.

Special thanks to Myroslav Opyr (quintagroup.com) for all his
suggestions and code patches and to a vocal group of OS X users
(https://github.com/zatosource/zato/issues/41) who helped create the OS
X installer!

Changelog: https://zato.io/docs/project/changelog.html

Unfortunately, this release doesn’t add an installer for RHEL and SLES.
Confronted with a choice between delaying 1.1 and adding support for OS
X and Fedora, I had to make a call and chose the latter.

Changelog

  • Unified installer for Ubuntu, Mint, Fedora and OS X

  • Added the zato check-config command

  • Fixed a bug which lead to double execution of user-defined scheduler jobs

  • Made quickstart clusters more robust when confronted with improperly
    configured servers, sanity checks are now performed before servers are
    started

  • Changed the default value of main.deployment_lock_expires so it works
    on 32-bit systems without a need for reconfiguring servers after they’re
    created

  • Made scripts generated by zato quickstart relocatable

  • Newly created servers start CPU_COUNT gunicorn workers by default now,
    not CPU_COUNT * 2 as previously

  • HAProxy load-balancer can now bind to all interfaces. Patch provided
    by Myroslav Opyr (quintagroup.com).
