gRPC APIs for Twisp. Deployed alongside our existing GraphQL APIs. Review the schemas at https://buf.build/twisp/api.
Custom balances for rolling up balance calculations across user-defined dimensions and filters. Create new custom balances with createCustomBalance; query balances with customBalance andcustomBalanceByCode.
Support updating the entries, params and transaction fields of a transaction code with updateTranCode.
Post transactions with a specific version of a tran code: the postTransaction mutation now supports a tranCodeVersion parameter.
Fix issue with concurrent put for transactions, ensuring that active records aren't overwritten after a record lock.

Default journals in every ledger. In many cases, users only need a single journal, so now every ledger will contain a default journal (with code DEFAULT). This also simplifies many common queries by making the journalId filter option optional - it will use the default journal if not provided.
New Journal.code field, an optional unique code for journals.
Support for Global Object Identification in the GraphQL API. All persistent core accounting models in the GraphQL schema now implement the Node interface, meaning that they have a globally unique id field and can be queried using the global Query.node field.
Integrated timestamps into transactional operations: mutation operations committed within the same transactional context will have the same created and modified timestamps in the same way that Postgres now() and CURRENT_TIMESTAMP works.
Configurable account sets with AccountSetConfig. For now, the config only has one option enableConcurrentPosting that optimizes the account set for a ridiculously high rate of entries written. The tradeoff is that read operations for balances become much more expensive and slow; to be used with caution.
Regional WAFs are deployed in every account/region.
Suite of Tutorials published on the docs site, including the "Twisp 101" tutorial and a set of "Foundations" tutorials covering the basic operations for the ledger.
Additional reference documentation on the API covering concepts like pagination and the various error types.

Historical indexes can be created to query all versions of records' histories. While regular indexes (such as those created by the schema.createIndex mutation) will index the most recent version of records, a historical index will index every version.
Indexing & filtering by multiple sort/partition keys in custom indexes. Querying custom indexes accepts a list of CustomIndexFilter to enable filtering by on indexes with multiple index keys.
Decimal type IndexKeys allow creating more flexible custom indexes.
Money type arithmetic & logical operations in CEL. CEL expressions can now perform basic infix operations on money types, e.g.: money("1.15","EUR") > money("1.14","EUR").
Enable AWS Backups for business continuity plans (BCPs).

Concurrent postings for high throughput accounts allows low cardinality accounts like settlement accounts to have postings at high throughput, while maintaining all transactional guarantees at the cost of slower reads of balances on the account.
Administrative APIs for managing user access to Twisp for your organization and managing Twisp tenants under your org.
