## 2024-04-21 Gabriele Cosmo (prophonon-V11-02-00)
- Fixed compilation error in G4LatticeManager on Windows VC++ with
  C++20 Standard enabled.
  Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).

# History entries prior to 11.0

16 April 2021 Ben Morgan (prophonon-V10-07-00)
-----------------------------------------------------
- Migrate build to modular CMake API

28 May 2020 Ben Morgan (prophonon-V10-06-00)
-----------------------------------------------------
- Name module "G4solidstate_phonon" for use with new CMake system,
  as old "G4phonon" name clashes with solidstate/channeling"

8 October 2014  Michael Kelsey (prophonon-V10-00-01)
----------------------------------------------------
- G4LatticeManager:  Change to globally shared object (simple "static", not
  G4ThreadLocal).  Fixes null-pointer crash in MT phononExample.

13 March 2014  Gabriele Cosmo (prophonon-V10-00-00)
---------------------------------------------------
- Removed inline keywords in methods in G4PhononDownconversion.cc
  and make coherent use of G4 types.

15 November 2013  Michael Kelsey (prophonon-V09-06-07)
------------------------------------------------------
- G4PhononDownconversion.cc:  Address Coverity #53462, initialize data
  buffers in ctor.

- G4PhononReflection.cc:  Address Coverity #53407, throw exception if input
  track polarization is invalid (i.e., track is not a phonon).

- G4LatticeManager.hh:  Address Coverity #53461, drop lattice counters.

- G4LatticeReader.hh:  Move ctor, dtor implementations to .cc file; fix
  comment on psLatfile, as stream is owned by reader.

- G4LatticeReader.cc:  Address Coverity #53491-53495, check input data fNX
  and fNY against allowed size of lattice array (G4LatticeLogical::MAXRES)
  before using them.  NOTE:  Requires materials-V09-06-32 or later.

15 November 2013  Michael Kelsey (prophonon-V09-06-06)
------------------------------------------------------
- G4VPhononProcess.cc:  Add verbosity reporting of vgroup before and after
  rotation.

13 November 2013  Michael Kelsey (prophonon-V09-06-05)
------------------------------------------------------
- G4LatticeManager:  Avoid double-delete at end of job by registering unique
  lattice pointers into std::set<>, and deleting those instead of std::map
  entries.  Supporting non-virtual utility functions for use in ctor/dtor.

12 November 2013  Michael Kelsey (prophonon-V09-06-04)
------------------------------------------------------
- G4LatticeReader.cc:  Per G.Folger, errors processing input file should
  throw fatal exception, not return null pointer.

12 November 2013  Michael Kelsey (prophonon-V09-06-03)
------------------------------------------------------
- G4VPhononProcess.cc:  Add verboseLevel-controlled output to show
  generation of secondaries.

- G4PhononDownConversion.cc, G4PhononScattering.cc:  Add verboseLevel output
  to show MFP.

11 November 2013  Michael Kelsey (prophonon-V09-06-02)
------------------------------------------------------
- G4PhononTrackMap:  Move implementation of Clear() to .cc file.  Called
  from constructor to try to ensure that map data member isn't wonky on
  Windows.

6 November 2013  Michael Kelsey (prophonon-V09-06-01)
-----------------------------------------------------
- G4LatticeReader.cc:  Fix compiler warning about implicit cast of string
  literal to char*, by casting getenv() to (const char*).

5 November 2013  Michael Kelsey (prophonon-V09-06-00)
-----------------------------------------------------
