Release Notes for 1.1.17

o BUG-FIX: Save symmetry coordinates is fixed

o BUG-FIX: Colour-by-B-factor colours are fixed

o FEATURE: Full doxygen documentation transfered to chapi nanobind functions

o FEATURE: Anisotropic probability radius scaling (thank ClAuS Flensburg)

o CHANGE: For packagers: Now a commonly-used fragment of the monomer library
is bundled with Coot. Unknown monomers are now downloaded from GitHub
and cached using XDG Base Directory Specification

o CHANGE: For packagers: Now the reference structures are bundled
with the source code (and installed) - no longer do they need
to be a separate dependency

o CHANGE: If a map has a PANDDA:: or APPLY-SYMMETRY:: label then Coot now
properly handles that (turns off "is-EM-map" status)

o CHANGE: Atoms with Zero Occupancy results now moved into the
main window

o CHANGE: Boron atoms are now pinky-beige - like Jmol

o BUG-FIX: Fix crash on adding an atom [Clément Bousquet]

o BUG-FIX: Symmetry atoms are now clickable for distances and labels

o BUG-FIX: Fix the non-drawn clashes post model update

and now will work on macOS

overlay and now will work on macOS

o BUG-FIX: Fix the problem of focus-grab when using Tutorial Model & Data

o BUG-FIX: Fix the "Close" button in the Restraints Editor

o KNOWN-BUGS: (that I looked at at but don't know how to resolve):
- Ramachandran plot on macOS
- Menu items that use targets on macOS
(I suspect OpenGL driver bugs and GLib problems on macOS)

Mostly a bug-fix release, although I did manage to squeeze in feature - drag and drop now works.

• FEATURE: Drag and drop (partial - it works from the file browser,
  but not from CCP4i2)

• FEATURE: set_use_vertex_gradients_for_map_normals() added to the Coot API

• CHANGE: Fixed atoms are now draggable

• CHANGE: max-closeness is no longer used to filter peaks in map_peaks_py()

Moorhen and chapi

o FEATURE: Symmetry represented as solid model (no longer just lines)

o FEATURE: PAE Plots on downloading Alphafold models

o FEATURE: new chapi functions:

is_nucleic_acid()
delete_all_carbohydrate()

o FEATURE: Setting the primary mouse button for view rotation enables
secondary mouse button for zoom (like Old Coot)

o CHANGE: chapi modules name now changed to coot_headless_api
so that the molecules_container object can be called
chapi

o CHANGE: Alphafold downloads are now XDG Base Directory compliant

o BUG-FIX: NCS-jumping has been fixed - Bernhard Lohkamp

o BUG-FIX: unwritable XDG cache dir now longer causes a crash
[Jordan Dialpuri]

o BUG-FIX: About and Preferences dialogs can now be properly closed.

o BUG-FIX: Texture handling for bad NBC markers updated [Fixes crash]

Release 1.1.12

o TERMINAL OUTPUT: Coot's startup, in particular the graphics and Python, have
lately been problematic (i.e. flaky/broken). Different operating systems,
different drivers, and different versions of Python add to the complexity.
We have spent quite some time refactoring this - and especially so in the
last few weeks. To help understand what is going wrong on startup I have
increased the amount of diagnostic information on the terminal - so it's a
bit ugly at the moment.
When issues have been resolved and the startup is stable, I will reduce/remove
the diagnostics.

o FEATURE: new chapi functions:

add_terminal_residue_directly()
copy_molecule()
flood()
get_validation_vs_dictionary_for_selection()
servalcat_refine_xray()
get_torsion()
change_alt_locs()
split_residue_using_map()
get_missing_residue_ranges()
get_mutation_info()
set_temperature_factor_using_cid()
Pythonic API:
   https://www.mrc-lmb.cam.ac.uk/lucrezia/libcootapi-documentation/api.html
C++ API:
   https://www2.mrc-lmb.cam.ac.uk/personal/pemsley/coot/docs/api/html/

o FEATURE: New Coot API functions:

set_new_non_drawn_bonds()
add_new_non_draw_bonds()

o FEATURE: Added graphics viewport scaling

o FEATURE: Added Acedrg link interface

o FEATURE: HOLE interface has been restored

o FEATURE: Transform map by LSQ model fit has been restored

o BUG-FIX: --code now works again after XDG Directory Protocol
update

o BUG-FIX: Fix the use of the no-recentre-view in coordinate file open dialog

o BUG-FIX: Contact dots for ligands now show ligand donor to water H-bonds

o BUG-FIX: One can no longer refine using a CCD dictionary [Lorenzo Masso]

o BUG-FIX: Use the correct shader for surfaces in "Plain" mode

o BUG-FIX: LSQ Fit dialog now works

o BUG-FIX: CYS with hydrogen atoms no longer try to make SS bonds
[Jordan Dialpuri]

o BUG-FIX: End-of-chain TER atom now removed on adding a new terminal residue

o BUG-FIX: Dark mode icons now work in Layla

o BUG-FIX: Use a wider window on startup on macOS

o BUG-FIX: Global Phasing column labels F_early-late now auto-read
