TeXstudio is a platform-independent, fully featured LaTeX editor, which is supposed to make the writing of LaTeX documents as easy and comfortable as possible. Some of the outstanding features of TeXstudio are an integrated pdf viewer with (almost) word-level synchronization, live inline preview, advanced syntax-highlighting, and live checking of references, citations, latex commands, spelling and grammar.
The 2.6 brings a bunch of various new features and bug fixes.
For example: a better looking gui with retina display support and svg icons; alignment options for different environments; !TeX spellcheck = ... magic comment to specify file-level dictionaries; better bidi support for rtl languages; pweave highlighting; new completion files; and other stuff.
