New features

• Built-in viewer for most of Microsoft Office documents (DOC, DOCX, XLT, XLTX, PPT, PPTX) as well as MD, EPUB, FB2. To display such office documents, we use an internal converter that transforms their contents into HTML and displays it in the HTML viewer. This allows to protect users from executing any viruses and malicious scripts
• "Attachment auto-preview" option to allow automatic switch to the attachment's tab of the preview pane (if any)

Improvements

• Auto-refresh for OAuth tokens
• Exception on SetCurrentProcessExplicitAppUserModelID in Windows Vista

Fixes

• Double click word selection problem in the PureHTML editor
• Time Zone from .ICS import error
• Images from HTML templates were not displayed in the RichText editor
