Digia announced that Qt 5.4 Release Candidate is already available for downloading:
https://blog.qt.digia.com/blog/2014/11/27/qt-5-4-release-candidate-available/
According to the information from their team meetings this release candidate should be very close to release version which is expected later in December.
This version contains large number of bug fixes, also versions of MinGW and Mac OS used were updated. Now Yosemite is used for packaging.
List of new features in version 5.4 can be found here:
http://qt-project.org/wiki/New-Features-in-Qt-5.4
The most interesting thing, to my opinion, is that in this version they consider Qt WebKit module done. Though it will be supported in future, later they will be developing Qt WebEngine. It is a new module appeared just now and based on Chromium.
They are not going to support Qt WebEngine on all platforms, only some of them. You can read about that here:
http://qt-project.org/wiki/QtWebEngine#5405d8a903c83e89cb649f1b518ef1be
Many new features for WinRT and Windows Phone platforms were added in version 5.4.

Creating Web Application in Visual Studio 2013 Update 4
Templates used in Visual
Studio for web applications were updated a lot recently.
Imagine we need to create
ASP.NET Web Application using .NET Framework 4.5, Visual Studio 2013
with the latest Update 4 (available since November 12, 2014
http://www.visualstudio.com/news/vs2013-update4-rtm-vs#CodeLens).
Here we can add
Application Insights feature to your project which should help us to
understand what users are doing with our application, how often they
launch it, in what environments, etc. For our test application we
don't need it by now.
We will select Web Forms
now (we will select MVC template next time for our investigation). We
don't need unit tests and hosting in the cloud for this project. In
Change Authentication window we can change authentication from
Individual User Accounts (default) to No Authentication,
Organizational Accounts (i.e. Active Directory) or Windows
Authentication (Intranet application).
So pressing OK and our
template is being generated, actually got a lot of files!
We have Home, About,
Contact, Register, Log in pages though we haven't written a single
line of code yet. But what is more important we notice we have clean
URLs without .aspx – like in MVC. This is achieved with the help of
Microsoft.AspNet.FriendlyUrls library which was described by Scott
Hanselman https://aspnetfriendlyurls.codeplex.com/
. Together with this library we have ViewSwitcher control allowing to
switch between desktop and mobile views of the page.
Another techniques we
should pay attention to are bundling and minification. Rick Anderson
described them for Web Forms here:
Main target of using these
techniques is to improve request load time. Code for creating bundles
in in Global.asax.cs file. Look at Bundle.config file, there you can
add your own files as well.
ASP.NET identity (logging
in / registration of user) uses Microsoft OWIN Authentication
middleware for forms authentication. OWIN (Open Web Interface for
.NET) is an open source project which defines interactions between
web servers and application components (owin.org). In References of
our solution there are several assemblies related to OWIN, for
example:
- Microsoft.Owin.Host.System.Web - contains an OWIN server that enables OWIN-based applications to run on IIS using the ASP.NET request pipeline
- Microsoft.AspNet.Identity.Owin - contains a set of OWIN extension classes to manage and configure OWIN authentication middleware

Microsoft releases Visual Studio Community Edition
Microsoft released Visual Studio 2013 Community Edition Update 4 (November 12, 2014):
http://www.visualstudio.com/news/vs2013-community-vs
This edition is free for individual developers even for building commercial applications. It is also free for everybody participating in open source projects.
Here is the nice short video introducing Community Edition:
http://channel9.msdn.com/Events/Visual-Studio/Connect-event-2014/040
I've already installed Community Edition for test. Main C++ and C# projects are in place and I am also able to compile and launch my old projects. .NET Frameworks are available from 2.0 to 4.5.1 with possibility to download later frameworks from web.
Visual Studio also suggests to install Python Tools and Tools for Apache Cordova (JavaScript).
At the whole, Community Edition seems to be great free replacement to Professional Edition.
