    • Internal:

      • An unnecessary allocation in getSpeciesByName() has been replaced by a more efficient cast.

      • The callback routines to compute the Jacobian and flow vector have been simplified by using arrays of reactant species instead of lists.

  • 0.13 was publicly released on 2012-03-30:

    • New:

      • Routines to get a copy of a network view, update a network view in a zone, remove a network view from a zone, check whether the parent network of a network view has been updated since the view was generated, to add or remove reactions to/from a view, and to iterate over network views stored in a zone have been added to the API.

      • A new technical report describes libnucnet views and how to use them.

    • Fix:

      • The user-defined function type Libnucnet__Net__screeningFunction has been changed to Libnucnet__Net__screening_function to be compatible with libnucnet naming standards. This is a backwards-incompatible change.

    • Reorganization:

      • The evolution network for a zone is now updated from a network view using the network view update routine; thus, the updateEvolutionNetwork() and restoreDefaultEvolutionNetwork() routines have been removed. This is a backwards-incompatible change.

      • The addCopyOfNetView() routine has been removed. The action of this routine can be replaced by a NetView copy and update.

      • Libnucnet__NucView and Libnucnet__ReacView no longer store the originally defining XPath; thus, the getXPath() routines have been removed.

      • The labels for a network view in a zone are no longer restricted to XPath expressions.

      • The API routine to retrieve a network view from a zone no longer creates the view if it does not exist. If it does not, the routine now simply returns a null pointer indicating that the user should create it and update it in the zone.

  • 0.12 was publicly released on 2011-12-30:

    • New:

      • The API routine to update user rate function data now has a check that the rate function is registered.

      • It is now possible to copy a Network view from one zone to another.

      • It is now possible to update the evolution network during a calculation. An example code has been added to demonstrate this capability.

      • Routines to get the largest nucleon numbers and abundances summed by Z, N, or A have been added to the API. Example codes have been added to demonstrate these routines.

      • A new routine returns the standard Jacobian.

    • Fix:

      • The usage statement in the example code update_reac_data_to_xml.c has been corrected (fixes 3371635).

      • Some documentation typos have been fixed.

      • The example Kunz et al. (2002) fit function and data have been corrected (fixes 3421904 and 3421906).

    • Reorganization:

      • The distributed code no longer refers to a version number. This may be obtained from the distribution directory name.

  • 0.11 was publicly released on 2011-07-18:

    • New:

      • A new API routine Libnucnet__updateZoneXmlMassFractionFormat() now permits the user to choose the format code for output of zone mass fractions to an xml file. An example has been modified to illustrate this new routine.

      • A new API routine Libnucnet__Zone__addCopyOfNetView() allows the user to copy an existing NetView to a zone. An example has been modified to illustrate the use of this routine.

      • A new example shows how to update a reaction xml file with a second reaction xml file and output the result to a new xml file.

  • 0.10 was publicly released on 2011-06-13:

    • New:

      • The defining XPath expressions for views may now be retrieved from views by new API routines. Examples illustrate these new routines.

      • It is now possible to apply a user-defined deallocator routine to data for a user-defined rate function.

    • Fix:

      • A missing cast in a net view look up has been added to allow a clean compile with g++ (fixes 3314818).

      • The default value for D_LARGE (the quantity governing how much larger the reverse rate can be relative to the forward rate) has been increased in Libnucnet.h.

      • Some documentation typos have been fixed.

    • Reorganization:

      • The regression test script now downloads data automatically.

  • 0.9 was publicly released on 2011-05-28:

    • New:

      • Code is now hosted at SourceForge.net.

      • The examples/ directory now includes a regression test script generator.

      • It is now possible to get views of nuclide and reaction collections and networks. New and modified examples demonstrate the use of views.

    • Reorganization:

      • Examples directory has moved to same level as src/.

      • Example codes now have descriptive names.

      • Data for example codes is now downloaded separately.

      • Extra data for user-defined rate functions are only stored in zones. This means getDataForRateFunction() is no longer in the API.

      • It is no longer necessary to set user rate functions for the Libnucnet__Reac structure after registering them. This means setUserRateFunction() and setUserRateFunctions() have been removed from the API.

  • 0.8 was publicly released on 2011-05-14:

    • New:

      • The user no longer needs to make the tmp directory for compiling example codes.

    • Reorganization:

      • The prototype for computeRate() has changed and now takes extra data as input. This is a backwards-incompatible change in the API.

      • The routine getDataForUserRateFunction() has been renamed to getDataForRateFunction(). This is a backwards-incompatible change in the API.

  • 0.7 was publicly released on 2010-09-06:

    • New:

      • Routines to copy a zone, compute a species quantum abundance, and a nuclear species binding energy have been added to the API. Example codes have been added or modified to demonstrate these new routines.

      • Darmstadtium, Roentgenium, and Copernicium have been added to the element name list.

      • The ability to include elements with unassigned names (for example, ubn--unbinilium--for Z = 120) has been added to the API.

    • Fix:

      • A number of documentation typos have been fixed.

    • Reorganization:

      • Parameters in example codes have been moved into defines.

      • Example codes that validate xml input now have flags to allow the user to turn off validation (default is to validate).

  • 0.6 was publicly released on 2010-05-03:

    • New:

      • Routines to output Libnucnet__Net and Libnucnet structures to xml have been added to the API. New examples demonstrate these new routines.

      • A routine to check the zone data against the webnucleo.org zone data schema has been added.

      • The zone data schema now checks that an input mass fraction lies between zero and one.

      • A check on the agreement between (z,a) and name of species in input zone data has been added in the zone data parser.

      • Checks have been added on input zones for routines on species abundances, abundance changes, and optional properties.

      • A check has been added to catch unregistered user rate function keys.

      • It is now possible to include di-neutrons in the reaction network.

    • Fix:

      • A number of documentation typos have been fixed.

      • A possible memory leak if update of user-defined properties fails has been fixed.

      • A missing tau in usage statement of single zone network example has been added.

      • Libnucnet__Nuc__getSpeciesByZA() no longer crashes when input Z larger than largest Z in network.

    • Reorganization:

      • Namespaces have been simplified. The prefixes have been removed; however, the parser should still be able to handle them in most cases.

      • Iteration over zone optional properties is now a direct scan. This is potentially much faster than in previous versions; however, the iteration order in no longer alphabetical by property name but rather by the order in which the properties are stored internally, an ordering the user does not control.

  • 0.5 was publicly released on 2010-01-11:

    • New:

      • Iteration over species, reactions, and zones now uses qsort() for ordering. This should dramatically speed up iteration of large collections.

      • It is now possible for the user to define his/her own rate function and to apply it to rate calculations. A new technical report describes and the examples now illustrate how to apply such rate functions.

    • Fix:

      • Libnucnet__Nuc__writeToXmlFile() now correctly outputs isomer.

      • Old single ground state is now correctly removed if species updated with ground and isomer.

      • Network evolution example codes now demonstrate Newton-Raphson iterations more correctly.

      • The prototypes of accessor routines have been changed to reflect const correctness better. This is a backwards compatible change.

  • 0.4 was publicly released on 2009-05-18:

    • New:

      • Two new examples demonstrate how to check that forward and reverse reaction rates lie within specified bounds and how to run a single zone network calculation with input thermodynamic and initial mass fraction data from a text file.

      • It is now possible for the user to specify the order in which reactions and zones are iterated over with their iterators. The user specifies these with user-defined compare functions that are set and cleared with API routines. The default iteration order for both reactions and zones is now based on their internal storage, which the user does not define. The default iteration for reactions or zones can be considerably faster than one requiring sorting and should be used whenever possible.

      • The routines Libnucnet__Species__updatePartitionFunctionData() and Libnucnet__Reaction__updateRateTable() now sort the input data by temperature before storing them.

      • The single zone evolution examples now use the new wn_matrix arrow solver by default (though the user can still change to use the gsl lu decomp routine). This requires an upgrade to wn_matrix 0.8 or later. The arrow solver can run much faster than the gsl lu decomp routine for large networks.

    • Fix:

      • The argument check for the single zone evolution example has been fixed.

      • A bug that caused the routine to compute the nuclear partition function to crash when the species only has two partition function points has been fixed. The similar bug for computing reaction rates from rate tables has also been fixed.

      • Some usage statements in the example codes have been fixed or made clearer.

      • Some typos in the documentation have been fixed.

  • 0.3 was publicly released on 2009-01-27:

    • New:

      • The following new API routines have been added: Libnucnet__Nuc__clearSpeciesCompareFunction, Libnucnet__Nuc__extractSubset, Libnucnet__Nuc__updateSpecies, Libnucnet__Reac__extractSubset, Libnucnet__Reac__updateReaction, Libnucnet__Reaction__Element__getName, Libnucnet__Reaction__Element__isNuclide, Libnucnet__Reaction__copy, Libnucnet__Reaction__free, Libnucnet__Reaction__iterateProducts, Libnucnet__Reaction__iterateReactants, Libnucnet__Reaction__new, Libnucnet__Species__copy, Libnucnet__Species__free, Libnucnet__Species__getPartitionFunctionLog10, Libnucnet__Species__getPartitionFunctionT9, Libnucnet__Species__updateMassExcess, Libnucnet__Species__updatePartitionFunctionData, Libnucnet__Species__updateSource, Libnucnet__Species__updateSpin, Libnucnet__Zone__getProperty, Libnucnet__Zone__iterateOptionalProperties, Libnucnet__Zone__new, Libnucnet__Zone__removeProperty, Libnucnet__Zone__updateProperty, Libnucnet__relabelZone, Libnucnet__writeZoneDataToXml

      • The structure Libnucnet__Reaction__Element has been added to the API. Reaction elements are reactants or products. API routines allow the user to get the names of the reaction elements, determine whether they are nuclides or not, and iterate over them.

      • Non-smoker fits now have high temperature limits. The default is 10 billion K, but the user may set this in the data xml file.

      • It is now possible to get mass fraction data in a zone by z and a or by the species name.

      • It is now possible to add, update, and retrieve optional properties for a zone. It is also possible to iterate over the properties.

      • It is now possible to sort the species with a user-supplied data compare function.

      • A number of new examples and their associated data demonstrate the new API capabilities.

      • Generated example xml files are now included in the distribution tarball. This allows users to run any of the examples right away.

    • Fix:

      • A number of documentation typos have been fixed.

      • The usage statement for the modified reaction rate single zone calculation has been fixed (bug reported by Tianhong Yu).

    • Reorganization:

      • The prototypes of a number of API routines have changed. These are backwards incompatibilities and users should update. The changed routines are: Libnucnet__Nuc__addSpecies, Libnucnet__Nuc__removeSpecies, Libnucnet__Reac__addReaction, Libnucnet__Reac__new_from_xml, Libnucnet__Reaction__addNonSmokerFit, Libnucnet__Zone__updateAbundanceChanges, Libnucnet__Zone__updateAbundances, Libnucnet__addZone, Libnucnet__new_from_xml.

      • The following routines have been removed from the API: Libnucnet__Reaction__getNumberOfProducts, Libnucnet__Reaction__getNumberOfReactants, Libnucnet__assignZonesFromXml.

      • The xml zone data schema has changed.

    • Internal:

      • The validity of reactions is now checked only when the network has been updated. This results in a good speed up of network calculations.

  • 0.2 was publicly released on 2008-08-01:

    • New:

      • Libnucnet now can apply user-defined routines and data to compute the effect of screening electrons on nuclear reaction rates. Several examples in the distribution demonstrate how to apply user-defined routines to reaction rate calculations and how to use them in single-zone or multi-zone nucleosynthesis calculations.

      • New routines allow a user to extract the abundances and abundance changes of a zone into gsl_vector structures.

      • Libnucnet now handles mu and tau leptons as reactants and products.

      • A new API routine now returns a Libnucnet__Reac structure containing duplicate reactions. Distribution examples demonstrate how to use this routine and how to then remove duplicate reactions.

      • Libnucnet now handles multiple fits for a non-smoker reaction.

    • Fix:

      • Re-indexing of all species after species removal has been fixed.

      • A bug that prevented a species abundance change from being updated when it is zero has been fixed.

      • Several typos in the documentation have been fixed.

      • The symbol for Francium has been changed from incorrect fe to correct fr (bug reported by Lih-Sin The).

    • Reorganization:

      • The xml tag for the mass excess has been changed from mass to mass_excess.

      • Species, reactions, and zones are now looped over by iterators. A user now supplies a iterate function to be applied during the iteration. The distribution examples have been modified to reflect this change.

      • Libnucnet__Zone__computeFlowVector() now returns a gsl_vector.

      • Libnucnet now builds a reaction string from addReactant() and addProduct() routines.

      • The routine to add partition function data now uses gsl_vectors.

      • The Q value calculation routine has been renamed.

  • 0.1 was publicly released on 2007-10-16:

    • New:

      • Initial Release
