    4645== Status of the 4.0 beta release 
     46 
    4747This newly build beta release has been widely tested before this announcement: 
    48 * All the reference configuration sucessfully complete the so-called SETTE tests: each reference configuration is running fine, is restartable (running in one step or with a restart gives identical results) and reproducible (identical results with two different domain decomposition) with optimised compiler options, and in debug mode 
     48* All the reference configuration successfully complete the so-called SETTE tests: each reference configuration is running fine, is restartable (running in one step or with a restart gives identical results) and reproducible (identical results with two different domain decomposition) with optimised compiler options, and in debug mode 
    4949* All the test cases give correct results 
    5050* Some longer runs on most of the Reference Configurations show satisfactory scientific results.

    5656== Release notes 
     57 
    5758     * '''AGRIF for embedded zooms: 
    5859         * Now compatible with new sea ice component 
     
    7576         * The first test cases available for now are: 
    7677            * CANAL: east-west periodic canal of variable size with several initial states and associated geostrophic currents (zonal jets or vortex) 
    77             * ICEDYN: east-west + north-south periodic channel.  The common configuration includes an agrif zoom (1:3) in the middle of the basin to test how an ice patch is advected through it but one can also test the advection schemes (Prather and Ultimate-Macho) by removing the key_agrif in the cpp keys. 
     78            * ICEDYN: east-west + north-south periodic channel.  The common configuration includes an AGRIF zoom (1:3) in the middle of the basin to test how an ice patch is advected through it but one can also test the advection schemes (Prather and Ultimate-Macho) by removing the key_agrif in the cpp keys. 
    7879            * ISOMIP: simple box configuration with an ice shelf with simple geometry on top. The purpose of this test case is to evaluate the impact of various schemes and new development with iceshelf cavities. The exact original setup is described [http://staff.acecrc.org.au/~bkgalton/ISOMIP/test_cavities.pdf here]. 
    79             * LOCK-EXCHANGE:classical fluid dynamics experiment that has been adapted by Haidvogel and Beckmann (1999) for testing advection schemes in ocean circulation models. It has been used by several authors including Burchard and Bolding (2002) and Ilıcak et al. (2012). The LOCK EXCHANGE experiment can in particulart illustrate the impact of different choices of numerical schemes and/or subgrid closures on spurious interior mixing 
     80            * LOCK-EXCHANGE:classical fluid dynamics experiment that has been adapted by Haidvogel and Beckmann (1999) for testing advection schemes in ocean circulation models. It has been used by several authors including Burchard and Bolding (2002) and Ilıcak et al. (2012). The LOCK EXCHANGE experiment can in particular illustrate the impact of different choices of numerical schemes and/or subgrid closures on spurious interior mixing 
    8081            * OVERFLOW: illustrates the impact of different choices of numerical schemes and/or subgrid closures on spurious interior mixing close to bottom topography. It is adapted from the non-rotating overflow configuration described in Haidvogel and Beckmann (1999) and further used by Ilıcak et al. (2012) 
    8182            * VORTEX: illustrates the propagation of an anticyclonic eddy over a Beta plan and flat bottom. It is implemented here with an online refined subdomain (thanks to AGRIF library) out of which the vortex propagates. It serves as a benchmark to diagnose nesting errors as in Debreu et al. (2012), Penven et al. (2006) and Spall and Holland (1991) 
     
    118119        * A new configuration, named ORCA2_OFF_TRC, was created to provide a benchmark simulation environment to deal with inert carbon tracers dynamics by exploiting the offline coupling with NEMO. 
    119120        * PISCES model contains new developments and modifications: 
    120           * Particulate Organic Carbon (POC) component comes with a new lability scheme, while the former Kriest parameterisation was superseded; 
     121          * Particulate Organic Carbon (POC) component comes with a new liability scheme, while the former Kriest parametrisation was superseded; 
    121122          * A complex iron chemistry scheme is now available, with an improved description of ligands for the marine iron cycle 
    122123          * Carbonate chemistry is based on MOCSY 2.0 routines (see Orr and Epitalon, 2015), by complying also with CMIP6 standards. 
     
    129130 
    130131     * '''Simplification and robustness 
    131          * Revised structure of namlist_ref/_cfg and default reference values. 
     132         * Revised structure of namelist_ref/_cfg and default reference values. 
    132133         * Lateral physics (LDF): simplification of user interface and removal of CPP keys 
    133134         * Vertical physics (ZDF) (modularity, share shear production calculation between TKE and GKS, removal of all ZDF CPP keys, removal of avmu & avmv, minimization of MPP comm.: ~15 removed) 
     
    142143     * '''Collaborative Development Environment         
    143144         * Access to information on NEMO wiki reorganised through portals  for users/developers/System Team and complete refactoring of all wiki pages and their layout 
    144          * Reorganisation of svn repository to be compliant with usual directory tree and faciltate building of NEMO executable 
     145         * Reorganisation of svn repository to be compliant with usual directory tree and facilitate building of NEMO executable 
    145146         * Define and install a separate repository for test cases to all easy contributions from the NEMO Users Community
