	Funding: Tango Community More than 40 laboratories use Tango Controls as a framework for their control systems. During its 18 years of existence, Tango Controls has evolved and matured. The latest 9.3.3 release is regarded as the most stable and feature-reach version of the framework. However, it makes use of already outdated CORBA technology which impacts all the stack, from the low-level transport protocol up to the client API and tools. The Tango Community decided to move forward and is preparing for so-called Tango Controls v10. Tango v10 is meant to be more a new implementation of the framework than a release of new features. The new implementation shall make the code easier to maintain and extend as well as remove legacy technologies. At the same time, it shall keep the Tango Controls objective philosophy and allows the new implementation to coexist with the old one at the same laboratory. The first step in the process is to provide a formal specification of current concepts and protocol. This specification will be base for the development and verification of new source code. Formal specification of Tango Controls and its purpose will be presented along with used tools and methodologies.

	The Tango HDB++ project is a high performance event-driven archiving system which stores data with micro-second resolution timestamps, using archivers written in C++. HDB++ supports MySQL/MariaDB and Apache Cassandra backends and has been recently extended to support PostgreSQL and TimescaleDB, a time-series PostgreSQL extension. The PostgreSQL backend has enabled efficient multi-dimensional data storage in a relational database. Time series databases are ideal for archiving and can take advantage of the fact that data inserted do not change. TimescaleDB has pushed the performance of HDB++ to new limits. The paper will present the benchmarking tools that have been developed to compare the performance of different backends and the extension of HDB++ to support TimescaleDB for insertion and extraction. A comparison of the different supported back-ends will be presented. https://timescale.com*

	This paper will present the state of of kernel developments in the Tango Controls toolkit and community since the previous ICALEPCS 2017. It will describe what changes have been made over the last 2 years to the Long Term Support (LTS) version, how GitHub has been used to provide Continuous Integration (CI) for all platforms, and prepare the latest source code release. It will present how docker containers are supported, how they are being used for CI and for building digital twins. It will describe the outcome of the kernel code camp(s). Finally it will present how Tango is preparing the next version - V10. The paper will explain why new and old installations can continue profiting from Tango Controls or in other words in Tango "the more things change the better the core concepts become".

This paper will present the state of of kernel developments in the Tango Controls toolkit and community since the previous ICALEPCS 2017. It will describe what changes have been made over the last 2 years to the Long Term Support (LTS) version, how GitHub has been used to provide Continuous Integration (CI) for all platforms, and prepare the latest source code release. It will present how docker containers are supported, how they are being used for CI and for building digital twins. It will describe the outcome of the kernel code camp(s). Finally it will present how Tango is preparing the next version - V10.
