11.15.07: HNMRazor v1.3.0 and CNMRazor v1.2.0 have been released. The new versions are compatible with ChemDoodle and have a few graphically improved components. The hydrogens also add in a geometrically correct manner now.
11.15.07: The HNMRazor and CNMRazor sites have been redone. Check them out!
07.15.07: When using MolGrabber, and selecting 'Use Shapes', all charges will be displayed inside of the atoms they are associated with.
06.19.07: HNMRazor v1.2.1 and CNMRazor v1.1.1 have been released. Here is a summary of the improvements:
- Added 'Use Guest Account' button to the login screen for easier access.
- Enhanced application icons for Windows.
- Cleaned up spectra for Windows.
- Added spectroscopic techniques to HNMRazor, including presaturation and decoupling. These can be accessed in the Conditions menu, after pressing the 'Get Spectrum' button, by pressing the 'Techniques' button.
- The GUI has received a drastic upgrade for drawing molecules.
-Double, triple, aromatic bonds have been cleaned up.
-You can choose between saturation widths in the 'Options' Menu.
-Double bonds will now orient towards the middle of a ring.
-Aromaticity is detected, and circles will be drawn to indicate aromaticity if the option is selected in the 'Options' menu.
-A new Ring Toolbar has been added for easy ring addition, located in the 'View' menu.
-The shift key now breaks from the 6 angle system, allowing any molecule imaginable to be drawn.
-The system uses artificial intelligence to consider where to attach bonds to when shift is held.
06.19.07: Updated the graphics for MolGrabber and the Accounts section. Double and triple bonds are rendered clearer and double bonds in rings are checked more accurately.
06.01.07: Support for versions of HNMRazor before 1.2.0 and for versions of CNMRazor before 1.1.0 have been discontinued.
04.26.07: We have upgraded the molecule graphics for mol2png and icl2png, which affects the graphics in MolGrabber and the accounts section. Tell us what you think. The NMRazors also have this change, but the next versions will not be released until a later date.
04.07.07: Heteroaromatic shift predictions have been drastically improved. Additionally, HNMRazor and CNMRazor now detect aromaticity without using resonance (1.5) bonds. However, if you would like to force a specific resonance contributor, use the resonance bonds.
03.29.07: Added incremental constants to deal with nitrogen heteroatom effects in aromatic rings.
03.16.07: Added student instructions for the classroom, in .doc format for HNMRazor and CNMRazor.

03.13.07: The site Privacy Policy has been updated to version 1.2.
03.12.07: Added a "Register University" function to the accounts section so you can register your university if it isn't already registered for the forums.
03.05.07: Added a "Report a Glitch" function to the account section. Here you can describe any problems you are encountering and we will do our best to fix it ASAP.
02.11.07: CNMRazor v1.0.0 has been released. Keep in mind the popups are incomplete. Also, www.cnmrazor.com is up, so check it out. In the next coming weeks, vinylic and aromatic shifts will be improved for HNMRazor, and J Constants will begin to be simulated.
02.09.07: HNMRazor v1.1.4 has been released. This version includes a much more robust print function, and new popup for integration, and is compatible with CNMRazor. It also has a much improved visual spectrum for Windows, so there will be no more fuzzy peaks.
