Zato 3.1 changelog

#1

Hello,

I am happy to link you to the preliminary Zato 3.1 changelog:

https://zato.io/docs/3.1/project/changelog.html

Most of the functionality is already implemented while the rest is in development, to be released in June 2019.

This will be an incremental release, building on the already existing strong foundations.

For now, this is a list of additions or features changed and documentation for programmers and administrators will be added before the final release.

If you would like to use Zato 3.1 already, it is best to install it from source code.

Cheers, @dsuch!

Bit by bit (due to lack of time), I’m currently trying to install the latest version of Zato (main branch) from sources on a Docker container using Ubuntu 18.04, using Python 3.6.

So I’ll be testing some of these new, wonderful features one of these days and try to provide feedback.

Keep up the good work!

Excellent. With the speed of moving things in my company, it will take some time until I can validate my services against the new version, but keep up the good work!

I am installing the latest version of the main branch of Zato from sources inside a Docker container running Ubuntu 18.04:

cd /opt
git clone https://github.com/zatosource/zato
cd zato
./code/install.sh -p python3

And I just found these warnings during the execution of the installation script:

You may want to adjust versions in the requirements file. :slight_smile:

Also there is a missing dependency: tzdata. After installing the package via apt I no longer got the following error while executing /opt/zato/code/bin/zato --version:
