v0.927

Notes for 0.927 release:

The internal structure has been reworked so that the HDF5, EOS, and
particle libraries are always included and there is only one library
file, libo2scl.

Constants, unit conversions, the find_constants class, and the
associated documentation have been improved.

The boost integration and multiprecision libraries are now enabled by
default. The precision parameter in the dtos() function has been updated
to automatically output either digits or max_digits as requested by
the user. Multiprecision support has been improved throughout.

The old cubature classes have been removed but there is still a
./configure flag for cubature support (principally for the separate
EOS code which is under development).

Classes funct_python, fermion_rel, polylog, eos_quark_njl, nstar_cold,
eos_had_rmf_hyp, multi_funct_python, mm_funct_python, interp_krige,
interpm_krige, inte_qagi_gsl, inte_adapt_cern, eos_had_base,
bessel_K_exp_integ_boost, nucmass_dz, calc_utf8, convert_units,
boson_rel, part_pdg, and inte_double_exp_boost, have been updated.

Class eos_cs2_const was removed since its functionality is in
contained in eos_tov_linear.

New classes eos_leptons, emulator, emulator_python,
emulator_interpm_idw_table, fermi_dirac_integ_bf, part_funcs, and
eos_quark_njl_vec have been created.

The strings_spec function has been updated. New function unc_to_string()
has been added.

The ex_eos_gibbs and ex_lambda examples have been updated.

The C++/python interface and the yanic executable have been significantly
improved. The python interface is much more detailed and there has
been corresponding work on the examples in o2sclpy.

The Doxygen XML and run-time acol documentation has been synchronized
so that acol documentation will be clearer and more easily updated.
A corresponding new "vec_vec_string" type has been added to acol
and hdf_file. New command 'ninteg' was added to acol.

New index classes ix_fixed, ix_sum, etc. have been created for index
specifications. These are used in the tensor rearrange_and_copy()
functions.

v0.926

Notes for 0.926 release:

The gen_test_number class has been rewritten and improved to allow for
more flexbility.

Improvements to polylogs and associated testing.

Started process of using C++ std random number generators instead of
GSL.

Improved the verbose output in root_brent_gsl, the behavior of
tensor::rearrange(), the polynomial classes (especially for larger
floating-point types).

Improved OpenMP integration.

Created functions to compute KL divergence and a new set of classes,
matrix_invert_det to handle the inversion and determinants with Eigen
or Armadillo.

Updated to more recent versions of AME and FRDM.

Created a new vector_autocorr_fftw function for autocorrelations.

The fnmatch() function is being replaced by regex, enabled if
O2SCL_REGEX is defined. This is not yet enabled by default, because it
has caused some problems with o2graph.

A new version of the calculator class which partially supports UTF8 is
in implemented in calc_utf8. This new UTF-8 compatible class is used
in O2scl unless O2SCL_NO_CALC_UTF8 is defined. There are still some
complications with regex and UTF8 which haven't fully been resolved.

The convert_units class has been reworked to enable UTF8 support.

Created a new set of HDF5 input functions, hdf_input_n(), to allow
input with or without a name.

More work on the python interface everywhere and the snapcraft
configuration.

Improved citations for nuclear masses, handling of electrons and
photons in eos_sn, the fermion_rel nondegenerate expansion, the
fermion_rel pair_density() function, the nstar_cold class (including a
small change to the default crust), the fermion_mag_zerot class, the
tov_love class, the eos_tov_buchdahl class, the command ser-hist-t3d
in acol, the function table3d::create_hist_set().

eos_had_virial_spin. Progress on the experimental interp_krige
classes.

Improved documentation everywhere.

Cleaned the "acol -commands" and "acol -help" output.

refactored to use \ref integ_iu(), \ref integ_il() and \ref integ_i().

Improved error handling and documentation in cloud_file.

Several updates to eos_sn, nstar_rot, eos_had_rmf, eos_had_rmf_hyp_ts,
and ex_eos_gibbs. Created new beta-equilibrium functions in some
EOS classes. Created new function nucmass_fit::fit_covar() to
fit nuclear masses with a covariance matrix.

Improved integration between acol and o2sclpy.

Improved the handling of aliases in acol and cli.

Generalized convert_units, several of the integration classes, a few derivative and solver classes, and several of the particle classes to templates to allow for other floating point types.

A new class slack_messenger was created to send messages to Slack.

v0.922

Notes for 0.922 release:

In the table class, the set() function no longer automatically adds
rows or columns. This prevents some behavior which was not intuitive for
users.

Several tensor functions have been added, including
tensor::swap_data(), tensor_out(), tensor::min(), tensor::max(),
tensor::copy(), tensor::is_valid(). Slicing for tensor_grid objects
has been improved. Copy constructors for tensor and tensor_grid have
been created.

New vector_autocorr() functions were created to analyze
autocorrelations.

The class serach_vec now has improved thread safety.

created. These are still a bit experimental.

A new Robbins-Monro iteration root-finding class has been created. A
class smooth_func for smoothing multivariate functions by averaging in
a neighborhood has been created. These should help dealing with noisy
functions.

All 'funct11' classes have been renamed to 'funct'.

New vector bin size functions have been created.

The 'acol' command has been reworked to handle HDF5 I/O for more
types. It can now manipulate vectors, matrices, and tensors
in several new ways. The interaction with o2graph in o2sclpy
has also been improved.

The Markov chain Monte Carlo classes have been updated, but
are still experimental. Similarly with the probability
density distribution classes where new bivariate gaussian
and AMR-like probability densities were created.
