Steps to reproduce:

1. On an Alloy sample site, access admin view and enable "English" - "en" and "English (United States)" - "en-US".
2. Set up multiple sites. The main site (site A) has 'en' master language and the secondary site (site B) has 'en-US' master language. Site B just contains a start page.
3. Under Manage Websites of admin view, select Use site-specific assets for both sites.
4. Configure site A with Culture = en, Type = Primary, Scheme = HTTP.
   Configure site B with Culture = en-US, Type = Primary, Scheme = HTTP.
   Remember to remove the wildcard host name.
5. Go back to edit view and select site A. In the assets pane, select Media and create a folder named image under For This Site.
6. Upload an image to the image folder.
7. Select a page that has version in "en" only, for example, Alloy Meet. Add the uploaded image to the Teaser image property of this page. Then publish the page.
8. Export the Alloy Meet page from site A by going to admin view > Tools and select Export Data. Leave the default options selected and click Export content items to export the page.
9. Import the Alloy Meet page to site B by going to admin view > Tools and select Import Data. Select the Update existing content items with matching ID check box, and select English (United States) in this step. Upload the export file.
   Please note that the page exported does not have a en-us language version! However, some content has been imported.
10. Still in site B, check the Media assets pane. The image in the image folder has been imported.
11. Edit the imported image, move the mouse over the Download this file to get the link of this file, it will be something like: http://testhost:1839/sitesassets/image/darwin.gif
12. Browse to this URL _http://testhost:1839/sitesassets/image/darwin.gif_.

Expected result:

The image is displayed.

Actual result:

An "HTTP Error 404.0 - Not Found" error is displayed.

QueryableNotificationUsersImpl.FindAsync is used to find users based on their username, not by exact match, but by pattern match. This will basically do a full scan on AspNetUsers table.

If a customer has many users registered, it can be a major bottleneck.

Add page view tracking to the platform navigation in CMS. This tracking only occurs if tracking is already enabled through another add-on, such as Labs.BlockEnhancements. 

Inline block editing features have been moved from the Episerver Block Enhancements Labs add-on to CMS UI.

This feature allows editors to edit block content in a "quick edit view" without changing the current content context. A dialog box with an editable form is opened by selecting Quick Edit from the block's content menu.

In the inline edit dialog box, editors can also publish the block, mark the block as Ready to Publish, or send the block to review depending on the context and user's access rights.

See Linh Nguyen's blog post and the developer guide topic Inline edit blocks for more information.

This bug happens for BLOB downloads when they are sent to the client asynchronously and URL rewrite is configured to inject the Application Insights JavaScript.

It looks like it is related to Response.Flush called. When commenting out this line, it starts to work.
Similarly, when adding a Response.Flush() call after the synchronous transmit-method that will also start failing. Otherwise, when it copies with stream.CopyTo(), it will read/write to the stream without a flush and that works as expected.

Steps to reproduce

• Install URL rewrite (older version is installed by default, it needs version 2): https://www.iis.net/downloads/microsoft/url-rewrite
• Enable rewrite-config: C:\Windows\System32\inetsrv>appcmd unlock config /section:allowedServerVariables
• Setup IIS site for Alloy
• Install EnvVarProvider dll: gacutil /i Microsoft.Web.Hosting.EnvVarProvider.dll
• Setup environment variable: APPINSIGHTS_INSTRUMENTATIONKEY = d06bb9f2-1af0-428c-baed-a9626a5fbdf1
• Setup environment variable: APPINSIGHTS_JAVASCRIPT_ENABLED = true
• Set connection strings to use azure resources
• Upload a .html file to media assets
• Download the .html file from media assets

Result
File is partially downloaded or browser reacts with a network error.

According to Google, alternative links need to be outputted in an absolute URL format. This does not seem to be the case with the built-in alternate links extension in Episerver, resulting in incorrect behavior with Google complaining.

Example of output of the extension method for the episerver.com site:

<link href="/" rel="canonical" />
<link href="/" hreflang="en" rel="alternate" />
<link href="/de" hreflang="de" rel="alternate" />
<link href="/se" hreflang="sv" rel="alternate" />
<link href="/no" hreflang="no" rel="alternate" />
