+#### _eFMI® Standard 1.0.0 Beta 1_ released
+
+The next [candidate-draft](https://www.efmi-standard.org/standard/#release-cycle-and-versioning), the _eFMI® Standard 1.0.0 Beta 1_, for the first official release of the _eFMI® Standard_ has been released! You can find it on the official eFMI® website, https://www.efmi-standard.org/.
+
+This is the first Beta release since the last candidate-draft, the Alpha 4. We are therefore now in beta phase, with each beta finalizing one model representation chapter.
+
+This release focuses on the Behavioral Model representation, whose specification has been finalized and significantly extended and improved to achieve semantic completeness. Among many features, eFMI® Behavioral Models support:
+
+ - testing of any other eFMI® model representation like Algorithm, Production or Binary Code
+ - equidistant and variable time grid scenarios, the former with well-defined acceptable time-deviation and the latter with well-defined interpolation semantic
+ - tolerances configurations defining the absolute and relative error tolerances of variables for various floating-point precisions
+ - mapping configurations defining how to map variables of any dimensionality (scalar, vector, matrix, or higher dimensionality) to reference trajectories stored in CSV files
+ - proper handling of time grids w.r.t. actual (i.e., used to conduct a test) and presupposed (i.e., assumed by the test provider) sampling times
+ - proper handling of units of reference trajectories and tolerances
+ - testing of error signals, including test scenarios with expected errors
+ - test scenarios with runtime recalibration of tunable parameters
+ - clear requirements on test environments and definition of how to conduct a test
+
+Besides the _"Behavioral Model representation"_ Chapter, Beta 1 also finalizes the PDF layout and support chapters, like:
+
+ - footer with standard version, current page number and total, licensing and website link
+ - use of single open source font family
+ - blank pages for correct printing
+ - _"Legal information"_ Chapter, now with colophon stating the licenses of used open source fonts, trademarks and disclaimer
+ - the title page, now with eFMI® logo.
+
+There are only minor improvements in the other chapters; they will be focused on and finalized in individual future Beta candidate-drafts. The plan for Beta 2 is to wrap up the current preamble with _"Abstract"_, _"Overview"_ and _"Introduction"_ Chapters into a single _"Overview"_ Chapter, wrap up and finalize Chapter 1, _"General Concepts"_, and Chapter 2, _"eFMU container architecture"_, into a single _"Common concepts"_ chapter, and finalize Chapter 3.1, the _"Algorithm Code manifest"_.
+
+Testing -- and how to define tests, store references, integrate the tooling subject to testing, and make sure different test environments agree on the test results for a certain tooling -- is certainly a hot topic for any Modelica Association standard and project. We sincerely hope that the _eFMI® Standard 1.0.0 Beta 1_ provides an excellent starting point for discussion and insights on the challenges of achieving well-defined semantics and completeness, even if "just" for something as "simple" as testing sampled data systems.

+If you have any general questions, feedback or improvement proposals for the _eFMI® Standard_, please follow the [reporting specification issues and new feature requests guidelines on our website](https://www.efmi-standard.org/standard/#reporting-specification-issues-and-new-feature-requests) or contact us on our _public_ mailing list, [`[email protected]`](https://groups.google.com/g/efmi-info) (no Google account required).
