Today's update (d75be48) brings with it the following changes:

Today's hotpatch (3b3bbbc) includes these changes:

Performance improvements

• Increased number of BlobMachine workers. Should allow fetching of more blobs concurrently.

Bugfixes

Performance improvements

• Fixed issue with thumbnail request handler sometimes crashing when generating thumbnail from an image object.

• Refactored a lot of request handlers, ensuring more consistent code. There is a small risk of regressions. Please report any unexpected behavior.

• Fixed an issue where alt and title attributes weren't rendered on thumbnails if the value was the empty string or the value 0.
• The template function get_group_member_count() now properly returns an array, even when the array contains only a single item.
