Welcome to IDA 7.0!
The biggest news is that IDA is a native 64-bit application! First of all it means that now it can eat all memory of your computer and thrash it :) But jokes aside, switching to 64-bit aligns IDA with other modern software and makes it more compatible with the rest of the world. For example, IDAPython integration will be easier and more streamlined because many operating systems nowadays come with the 64-bit Python preinstalled (32-bit Python won't work anymore).
Second, we took this change as an opportunity (since old 32-bit plugins won't work with 64-bit IDA anyway) to clean up the IDA API, make it more consistent and less confusing. If we failed or succeeded is to be seen, but we ourselves like the new API much more. The fundamental concepts remain the same and IDA did not lose any bit of its functionality during the cleanup. We minutely tested all changes and ensured that all our tests continue to pass as before or better. We also tried to make our 3 APIs: C++, Python, and IDC, to be closer to each other. Function names and their functionality are the same in most cases, but we tried to stay pythonic in Python and C++-ish in the C++ interface. Since the changes are huge and it is easy to lose your way, we prepared a Porting guide from the IDA 4.9-6.x API to the IDA 7.0 API which explains what has changed and how. We hope that it will greatly help you when porting your plugins to the new 7.0 API.
For Python and IDC we implemented a compatibility layer that will help you with your scripts. Most of them should run fine on 7.0 with very minor or no changes. We plan to turn off the compatibility layer in the next release, so please dedicate some of your time to port your scripts to run without it. See the IDA 7.0: IDAPython backward-compatibility with 6.95 APIs page for more info.
To make the transition even smoother, we are also publishing a 32-bit version of IDA. It can (and should) be only used to run old 32-bit plugins while you are porting them to 64-bit. The 32-bit version of IDA can read v7 databases but it lacks some very nice new features. Let us introduce them now.
Now IDA is a truly international application that can speak all languages of the world because it uses UTF-8 everywhere. All scripts and plugins can use it. You can use UTF-8 in the disassembly listing, including comments or even the function names. This is not what we advise, therefore odd characters in names require some fine tuning. See the IDA 7.0: Automatic discovery of string literals during auto-analysis page for all the gory details.
By the way, the existing databases will have to be upgraded to benefit from the UTF-8 encoding. We tried to make the upgrade process as simple as before but there is a catch: since old databases could use any encoding, IDA has to guess the old encoding on the fly. To learn how to help IDA with this error prone task, see the IDA 7.0: Internationalization page.
IDA now parses and annotates exception handling information and RTTI. We plan to improve the decompiler and IDA to take advantage of this information in the future.
We improved the OSX and iOS debuggers to handle OSX 10.13 and iOS 11. There are many changes under the hood but your experience should be the same as before or even better.

BUGFIX: source debugging: the status bar would show the file offset, but not the current address
BUGFIX: stack tracing was broken for x86_64
BUGFIX: the PDB plugin could cause internal error if called with invalid data (now it only results in a non-fatal warning)
BUGFIX: the SNES loader could interfere and cause IDA to exit on very large files (> 2GB)
BUGFIX: the decompiler would not take into account wide user-specified variables and would create additional variables that would overlap with them
BUGFIX: the navband could disappear when using a debugger that uses manual memory regions (e.g. iOS or GDB)
BUGFIX: the presence of the decompiler plugin on the disk without a license in ida.key would lead to error

BUGFIX: ui/qt: IDA could leave F11-style fullscreen while navigating around and/or performing other actions
BUGFIX: ui/qt: If IDA encountered an error at startup, it might not have had time to create the taskbar icon yet, sometimes leaving that error/warning dialog hard to reach
BUGFIX: ui/qt: Using special mouse buttons 4 & 5 to move forward & backward in history, would change the cursor coordinates
BUGFIX: ui/qt: deleting a script snippet would mark the one that gets selected afterwards as 'modified'
BUGFIX: ui/qt: double-clicking on the 1st member of a struct, would cause the view to jump
BUGFIX: ui/qt: it was impossible to select the font from some listing widgets
BUGFIX: ui/qt: on Windows or OSX when a screen reader is used (e.g., JAWS or VoiceOver), the IDA View-A will automatically switch to flat listing since graph views are not accessible
BUGFIX: ui: ExportData action would silently overwite the output file if it already existed
BUGFIX: ui: IDA could lose the preferences for synchronization between views (and possibly registers, in case of debugging.)
BUGFIX: ui: OSX: idaq64 would always launch idaq if a file was dragged onto the dock icon
BUGFIX: ui: On Windows, the "Load a new file" dialog wouldn't create a taskbar entry, meaning it could be hard to find it on the desktop if another window showed up in front
BUGFIX: ui: Renaming an unsaved script snippet could lose its contents

BUGFIX: ui: re-enabled building graph of code and data xrefs to current address
BUGFIX: ui: the "Functions window" could spend too much time refreshing the list of function names, even when no functions were modified
