Release Notes - Fauna 2.7.0
The Fauna team is pleased to announce the availability of Fauna 2.7.0.
This release brings numerous enhancements in security and usability.
Attribute-based access control (ABAC)
Attribute-based access control (ABAC) is designed as a replacement for Fauna’s current resource-based security model. It’s an alternative to an all-or-nothing security model and is commonly used in applications to restrict access to specific data based on the user’s role. Until 2.7.0, access within Fauna was restricted to 4 pre-defined roles. With ABAC, developers can define custom roles that match the applications' requirements and its data model, permitting access only to the data that the user needs to see.

Fauna Shell, on the web
Users can now access a web-based version of the Fauna Shell command-line from any browser, anywhere with an internet connection. FQL commands and functions can now be run directly in the browser. This is especially helpful for new users hoping to get started quickly with Fauna, without needing to install CLI tools on their local computer.

Renamed "Classes" and "Instances"
One of the biggest user-facing changes in this release is the renaming of "classes" to "collections" and "instances" to "documents". Usability testing has repeatedly surfaced these terms as a source of confusion for new users. As such, we have renamed these terms.
We decided to go with "collection" because it’s more inclusive of flexible data models and resonates well with developers from a NoSQL background. Because databases that use the term "collections" typically also use the word "documents" to denote the objects in those collections, "instances" have been renamed to "documents". We have also found that most new users start with document-based data models to improve productivity during the early prototyping stage of application development.
This rename appears throughout Fauna and the documentation, especially in the FQL reference.
Recursive user-defined functions
Recursion has been one of the most commonly-requested features from our community, so we have added the ability to make recursive calls to user-defined functions. Since recursive calls can be very resource-intensive, the number of calls is restricted to a hard limit of 200. An example use case would be a user creating a list of all of her friends' friends within 6 degrees of separation, so she could send them marketing information about her app.
Time to number functions
Fauna 2.7.0 introduces new time to number conversion functions.
Fauna has two special data types dealing with dates and times. The
first data type is
date, which stores a calendar date. The second is a
ts), which stores an instant in time expressed as a
calendar date and time of day. These new functions allow developers to
extract the year, month, day of month, day of week, day of year, hour,
minute, and second values from a timestamp field.
Here is a summary of these new functions. Reference coverage of these functions is available here.
List of issues fixed in 2.7.0
Numeric values now sort more predictably; previously, integers and floats could not be compared by value.
Fauna Enterprise now called Fauna Hybrid.
Inserts into the future are no longer permitted.
Numerous performance improvements.
Addressed an issue where duplicated error messages appeared if the index configuration was invalid.
