This release of Rstox (version 1.11) includes a number of improvements and new features, highlights of which are listed below. Rstox version 1.11 corresponds with the StoX version 2.7. Support for reading the NMD Biotic v3.0 in StoX/Rstox, which is the new format for biotic data (e.g. trawl samples) released early 2019 by the Norwegian Marine Data Centre (abbreviated NMD in Norwegian). Biotic 3.0 files are treated as biotic v1.4 files by StoX in the current release, and will be fully supported in future releases. Support for the Biotic NMD API v3, which supports versioning of the data through snapshots generated when there are changes to a data set (there is one data set per cruise). Support for the Biotic NMD API v2, with a few changes such as all platform entries returned from getNMDinfo("platform") and one row per species in the output from getNMDinfo("taxa"). Added the function StationSpecCatDensity in StoX, which returns abundance regrouped into species categories specified by a resource file. See the template "Station species category density" in StoX. Added the ECA (Estimated Catch at Age) model (Hirst et al, 2014, https://doi.org/10.1111/j.1467-9876.2004.00422.x). This is a preliminary version currently running on Mac OS only. Added the function prepareDATRAS() for converting single biotic files to the DATRAS format. See a full list of changes in the README file.
