- Changes in the rendering engine for higher quality shadows at a small performance cost. - Protein atoms can now be colored based on their residue (ARG, HIS, LYS...). - Protein atoms can now be colored based on their secondary structure (helix, sheet or loop). - Added a UI control to change the direction of the light source. - Several more elements can have their colors customized within the app: F, Na, P, Cl, K, Ca, Fe, Zn and I. - PDB file reading is now multithreaded, making the opening of bigger files much faster.

- Support to change the bond color in Ball and Stick visualization mode. - Fixed some stability issues in Ball and Stick visualization mode for all devices.

- Improved RCSB PDB file search, allowing to search for text on all fields and not using ID only - Fixes rendering bug on Intel Macs

- Solve crash on Ball and Sticks visualization mode when the file contained no bonds. - Solve a bug where "Show all models" option missing on iPhone when working with multi-MODEL files. - Subsections of options in the Appearance tab are now collapsible. - Added more atom types that are recognized and show the correct Van der Waals radius (Na, P, Cl, Ca).

- Faster rendering - Removed sidebar - Option for showing all MODEL records at once - Support for more subunit colors - Redesigned color options UI

FIX: Fixes a shadow rendering bug appearing on most devices. FIX: Fixes crash when trying to display small protein on older devices.

- NEW: Selectable atom radius for solid spheres and ball and stick visualizations. - NEW: Support for multi-model PDBs. - NEW: More atom elements are detected. - FIX: Fix crashes on some PDBs with HETATM records. - FIX: Fix chirality on molecules.

FIX: Fixes a crash on A10 and older devices.

- NEW: Animated changes for visualization and color changes. - FIX: HETATM records from PDBs are now properly read.

- NEW: Structures can now be viewed as a balls-and-sticks visualization. - Fixed a bug which prevented .xyz files from being opened.

- Fixed bug in Photo Mode which prevented images from being generated properly

- NEW: Photo Mode. Create and export publication quality images. - NEW: Softer, higher quality shadows. - NEW: Move tool. - NEW: Read .xyz files. - NEW: View trajectories in .xyz file as an animation. - NEW: View energies of trajectory .xyz files.

- NEW: Support for casting shadows on the structure viewer.

- Added suggestions to RCSB file download screen. - Fixed crash when the app entered background on some devices.

- New: choose custom colors for each atom element. - New: color the protein based on subunit/chain instead of atom element. - New: open .pdb files directly from other apps. - New: File Info tab now shows the authors of the PDB file (if available). - Fixed: PDB ID is now shown correctly in File Into tab. - Fixed: App no longer fails silently when opening a file from Import Files > Open.
