The supported linear birth-death-sampling processes now allow for both destructive and non-destructive sampling (see ?LBDP).

• gendat() now returns the deme for samples.
• The Strains model (see ?strains) now has a filtering code: strains_pomp().

This release fixes a bug in the curtail function.

This release includes simulators for two new models:

• 'Strains': in which 3 strains compete for susceptibles.
• 'TwoUndead': which is identical to the 'TwoSpecies' model, except in that strains persist as ghosts after their demise.

In addition, there are some improvements to the underlying library:

• It is now possible to have events in which lineages migrate when sampled.
• There is some additional error-trapping.

This release contains an improvement to the curtail() function, which can now truncate a genealogy from either the left or the right.

It also contains some streamlining of the underyling C++ library functions.

This release fixes an error in the filtering codes for the SEIR and Two-Species models.

There are also some changes to allow for simulation with multiple (batch) sampling.

A bug, introduced in the previous release, has been fixed.

This release fixes bugs.

This release fixes bugs in the two-species spillover model's simulation and filtering codes.

The filtering codes for the two-species spillover model are now working.
