Beta 4 is a service release to EwE 6.6 Beta, which fixes a range of issues encountered during the November 2018 Beta program. We are still not ready to release EwE 6.6 as one remaining nasty issue yet needs to be solved in the MPA optimization tool.
The next version of EwE, version 6.6, is available for public testing. We invite you to use this version for your EwE modelling activities and to report any issue that you encounter to the EwE development team. Until 21 December 2018 the EwE development will process user feedback to iron out glitches and prepare the best possible version for release in early 2019.
EwE 6.6 has gained a range of new features:
Native support for .eiixml files, handy for running the EwE core on non-Windows environments
Merge and split groups
Better spawning control over multi-stanza groups
Assess input uncertainty onto any component of EwE through Ecosampler
Better discard control, and fitting to landings and discards
Simplified interfaces for configuring environmental responses and changing response curves
Forcing or Other Mortality (M0) to implement mortality events
Better control when combining effort and fishing mortality to drive fisheries
CEFAS MSE plug-in
The Advection and Ecotracer modules have been overhauled
Better control how to drive foraging capacity, using priors, habitat affinity, and/or environmental responses
This is the last version of Ecopath 5, prior to the overhaul to .NET and the subsequent releases of EwE 6. Ecopath 5 contains a few features that were not migrated to EwE 6 for various reasons; you might want to use this version if you need access to legacy features such as EcoRanger and the auto mass-balance routine. It is recommended to install Ecopath 5 on Windows XP. You might need to install a virtual PC environment.
This version will complain that it is outdated on launch. Just enter ‘Polovina’ in the panic box and Ecopath 5 will start.
Please note that we are no longer making changes to the Ecopath 5 source code; Ecopath version 5 is no longer being maintained.
