With the new ability to dump the OP2 directly to HDF5, this should not be an as much of

### pyNastran v1.0.0 has been released (2017/5/25)
This is a major release. The focus this time has been on robustness and testing.
Hopefully, it shows. The software has also been relicensed to be **BSD-3**, which
is a more permissive license and is the same one that numpy, scipy, and
matplotlib use.
Unfortunately, the GUI is more complicated.
- For open source projects : GPL 2/3
- For companies that pay a license to Riverbank : proprietary
- For companies that don't pay a license fee : GPL 2/3
However, you may distribute an unmodified binary.
- Programmatics:
- Dropping Python 3.3 support
- Adding Python 3.6 support
- Supports Python 2.7, 3.4-3.6
- [OP2](http://pynastran-git.readthedocs.io/en/latest/quick_start/op2_demo.html)
- preliminary random results (ATO/CRM/PSD/RMS/NO)
- improved geometry support
- MONPNT1/MONPNT3 reading
- MATPOOL matrices
- F06 scripts
- added a preliminary flutter (SOL 145) parser
- supports multiple subcases
- PK and PKNL methods supported
- `plot_Vg_Vf(...)`, `plot_Vg(...)`, `plot_root_locus(...)`
- input/output units
- mode switching not fixed yet

- SPC Forces, MPC Forces, Load Vector, Applied Load
- minimal control presently
- No Grid Point Forces (e.g., freebody loads, interface loads)
- signficant speedups
- [BDF](http://pynastran-git.readthedocs.io/en/latest/quick_start/bdf_demo.html)
- 312 cards supported
- faster node transforms using:
```python
>>> icd_transform, icp_transform, xyz_cp, nid_cp_cd = get_displacement_index_xyz_cp_cd(dtype='float64, sort_ids=True)
>>> xyz_cid0 = transform_xyzcp_to_xyz_cid(xyz_cp, icp_transform, cid=0, in_place=False)
```
- simplified card adding
```python
>>> model.add_grid(nid, xyz=[4.,5.,6.], comment='nid, cp, x, y, z')
```
- comments can now be created without worrying about `$` signs
```python
>>> model.add_card(['GRID', 10, None, 4.0, 5.0, 6.0], comment='GRID comment\ngrid,nid,cp,x,y,z')
```
```
$GRID comment
$grid,nid,cp,x,y,z
GRID,10,,4.0,5.0,6.0
```
- unit conversion
- [GUI](http://pynastran-git.readthedocs.io/en/latest/quick_start/gui.html)
- buttons for picking, rotation center, distance
- PyQt5 support
- QScintilla & pygments support for scripting code editor

--------------------------------Future--------------------------------
Overall Notes
-----------------------v1.2.0 released 2019/5/21-----------------------
Programmatics:
- This is the last Python 2.7 release.
- Dropping Python 3.5 support
- Supports Python 2.7, 3.6-3.7
- GUI is compatible with PyQt4/PyQt5 as well as PySide/PySide2
- improved testing of old versions of packages

Added BDF
- *** SET2,PEALST,DMI,CONM1
BDF:
- 373 cards supported (up from 343)
- added abiltity to write models to separate include files
```python
>>> model = BDF()
>>> model.read_bdf(bdf_filename, save_file_structure=True)

out_filenames = {
bdf_filename : bdf_filename_new,
include_filename : include_filename_new,
}
>>> model.write_bdfs(out_filenames, relative_dirname=None, is_windows=None)
>>> ifile = model.grids[1].ifile
```

- HDF5 import/export
```python
>>> model = read_bdf(bdf_filename)
>>> model.export_hdf5_filename(hdf5_filename)
>>> model_new = OP2()
>>> model_new.load_hdf5_filename(hdf5_filename)
```

- preliminary superelement support
```python
>>> model.read_bdf(bdf_filename)
>>> model.superelement_models[1].nodes
```

Overall OP2
- ***added support for SORT2

BDF Bug Fixes
BDF API Additions
OP2:
- reorganization of random op2 results into op2.results.psd (or ato, no, crm, rms) to aide in finding data
- reorganization of op2 class to reduce number of functions in the object. This affects any custom table reading.
- improved optimzation response reading
- limited SORT2 support
- fixed CD transformation bug for BOUGV1 and BOPHIG1 tables
- Improved HDF5 export/import support (e.g., matrices, random results)

- Can optionally save directly to HDF5 instead of numpy (limited).
- Loading OP2s to an HDF5 file to decrease memory usage
```python
>>> op2_model = OP2()
>>> op2_model.load_as_h5 = True
>>> op2_model.read_op2(op2_filename)
```

OP2Geom:
- HDF5 support
- reading EQEXIN/S, GPT, GPDT, CSTM/S tables (recovery of nodes & coordinate with OP2Geom)
- fixed theta/mcid reading for CTRIA3/CQUAD4
- fixed CQUAD8 bug

Removed BDF
GUI:
- sped up HTML logging
- much improved groups menu
- options for Nastran in preferences menu to speed up loading/limit memory usage
- pyNastran BDF pickle reading
- pyNastran OP2 HDF5 reading (not MSC's format)
- visualization when pickling nodes/elements
- min/max labels
- highlight menu
- Patran-style colors
- custom force vectors
- AVL support

Overall OP2
- added plotting support for "standard" results (***complex)
- ***complex results may plot in real/imag or mag/phase or PSD
(power spectral density)
- ***no temperature, stress, element forces, energy


Overall F06
F06 Reader
F06 Writer

Solver
- not released
- rewriting pyNastran solver (SOL 101)
- improved support for 3D
- uses case control deck to identify loads/BCs
- still uses dense matricies, but layout will be easier to add sparse
matricies later
- still need to build Kgg/Fg/SPC/MPC matrices, partition matrices,
solve, calculate responses
- added D matricies for PSHELL, PCOMP, PSOLID

-----------------------v1.1.1 released 2018/7/xx-----------------------
BDF:
- 'SUBCASE=5' supported in addition to 'SUBCASE 5' and 'SUBCASE = 5'

OP2:
- fixed type of a few random results (i.e., mpc_forces_NO was being slotted into mpc_forces_ATO)
- when result limiting, you can now use regular expressions
Known issues:
- Transient Pandas Dataframes will fail for newer versions of numpy/pandas. If anyone knows how to use a MultiIndex,
this is probably pretty easy to fix.

-----------------------v1.1.0 released 2018/6/26-----------------------
This is a major release. As in the v1.0 release, the focus has been on testing.
