Bug fixes

Add support for escaped characters and unicode characters in strings
Ensure datetimes work correctly in Eastern timezones
Ensure is::uuid() parses valid UUIDs correctly
Ensure LET statements throw errors correctly on failure
Ensure Record IDs are parsed correctly when defined as a string
Fix bug where escaped characters were not supported in regex values
Ensure datetimes with milliseconds or nanoseconds are parsed correctly
Ensure datetimes with partial timezones are correctly calculated
Ensure time::month() returns the month of the specified datetime
Ensure FETCH clauses fetch the respective data correctly
Handle connection errors properly when WebSocket clients disconnect improperly
Ensure HTTP session is not verified multiple times when requesting an invalid HTTP route
Use Accept header instead of Content-Type header for client content negotiation
Fix key scan range iteration in RocksDB, which caused SurrealDB to randomly crash

Performance improvements

Miscellaneous performance optimizations and code cleanup
Limit maximum allowed runtime and memory in JavaScript functions
Ensure crypto and rand functions do not allow unbounded resource usage
Ensure read-only transactions are used when write functionality is not needed when using TiKV distributed storage engine

Embedding subquery results

SurrealDB now allows you to use the resulting Record IDs of a subquery, and embed them within another record, without having to specify the id field specifically.

// It is now possible to define a new Record ID as normal
LET $friend = (CREATE person SET name = 'Jaime');
// There is no need to select the `id` field using `$friend.id`
CREATE person SET name = 'Tobie', friend = $friend;

Using specific Record IDs

SurrealDB now supports the ability to set a specific reocrd ID in the record content itself when creating records using CREATE and RELATE statements.

// It is now possible to define a new Record ID as normal
CREATE person:test SET name = 'Tobie';
// Or by specifying the Record ID within the record data part of the query
CREATE person SET id = person:test, name = 'Tobie';
// In addition the ID can be specified in a CONTENT object
CREATE person CONTENT { id: person:test, name: 'Tobie' };
// Numbers can be used, and will be converted into a Record ID
CREATE user CONTENT { id: 1, name: 'Robert' };
// Strings can be used, and will be converted into a Record ID
CREATE city CONTENT { id: 'London', name: 'London' };
// UUIDs can be used, and will be converted into a Record ID
CREATE city CONTENT { id: '8e60244d-95f6-4f95-9e30-09a98977efb0', name: 'London' };
// Complex values can be used, and will be converted into a Record ID
CREATE temperature CONTENT { id: ['London', time::now()], name: 'London' };
// Complex values can be used, and will be converted into a Record ID
RELATE person:tobie->knows->person:jaime SET id = knows:cofounder;

Support for deep-merge record updates

SurrealDB now supports deep-merging record changes, ensuring that only specified object fields are modified and overwritten.

// Create a record
CREATE person:test SET name.initials = 'TMH', name.first = 'Tobie', name.last = 'Morgan Hitchcock';
// Use the MERGE clause to deep merge objects, without overwriting any fields
UPDATE person:test MERGE {
  name: {
    title: 'Mr',
    initials: NONE,
  },
  tags: ['Rust', 'Golang', 'JavaScript'],
};

Dynamic expressions in Record IDs

Complex Record IDs now support dynamic expressions, allowing parameters, and function expressions to be used as values within the IDs. This is useful in a timeseries context, or for ensuring locality between specific records in a table.

// Set a new parameter
LET $now = time::now();
// Create a record with a complex ID using an array
CREATE temperature:['London', $now] SET
  location = 'London',
  date = $now,
  temperature = 23.7
;
// Create a record with a complex ID using an object
CREATE temperature:{ location: 'London', date: $now } SET
  location = 'London',
  date = $now,
  temperature = 23.7
;
// Select a range of records up to the current time
SELECT * FROM temperature:['London', '2022-08-29T08:03:39']..['London', time::now()];
