28 February 2019   632

Go 1.12 programming language released, which is being developed by Google with the participation of the community as a hybrid solution combining high performance of compiled languages with such advantages of scripting languages as ease of writing code, speed of development and protection from errors. The project code is distributed under the BSD license.

These are main updates:

  • Native TLS 1.3 support. It is not enabled by default, it is necessary to set the option tls13=1 in the environment variable GODEBUG (package crypto / tls).
  • Improved module system support. Developers are preparing to include it by default in version 1.13.
  • Windows support on ARM architecture systems. For example, Go can now be used with Windows 10 IoT Core on Raspberry Pi 3 boards.
  • Improved compatibility with upcoming versions of macOS and iOS. The layer for making specific system calls is the libSystem library.

Get more information at official documents.

Starting with Go 1.13, support for macOS 10.10 "Yosemite" will be discontinued, as the minimum supported version of macOS will be 10.11 "El Capitan". The next release also plans to end support for the FreeBSD 10.x branch.

CockroachDB to Change License Type

The only restriction in new bundle of licenses is the ban on selling commercial versions of CockroachDB, made in the form of cloud services

The developers of the distributed DBMS CockroachDB have announced the migration of the project source code into a bundle from the Business Source License (BSL) and Cockroach Community License (CCL), which is not free due to the discrimination of certain categories of users. The BSL license was proposed by MySQL co-founders three years ago as an alternative to the Open Core model. The essence of BSL is that the extended functionality code is initially available for making changes, but for a certain period of time it can be used for free only if the additional conditions are met that require a commercial license to be circumvented.

The new license allows the use of CockroachDB on any number of nodes in the cluster and embedding in applications, including those that are sold to customers or run as services. The only restriction that prevents the license from being considered free and open is the ban on selling commercial versions of CockroachDB, made in the form of cloud services. To issue a CockroachDB in the form of paid cloud services now requires the purchase of a commercial license.

As in the case of the re-licensing of MongoDB, Redis and TimescaleDB modules, the reason for the transition to a non-free license is the fight against the parasitization of cloud service providers who create derivative commercial products and resell open DBMS as cloud services but do not participate in the community and do not help in developing. It happens when the cloud providers, who are not related to the project, resell ready-made open solutions and benefit, but the developers are left with nothing.
