| Rell 0.10.3 | This release includes several enhancements. Function return types are now inferred automatically. Guard blocks separate argument verification from operation code. Queries can be called from code and REPL. A shorter syntax for nested namespaces is available. Operations return objects for constructing transactions and blocks. New functions rell.gtx.block and rell.gtx.tx aid in block and transaction manipulation. REPL now supports executing transactions and blocks. Named function arguments and default parameter values have been added. A Group By feature allows for data aggregation. New cryptographic functions, including sha256, keccak256, and eth_ecrecover, improve hash calculations and signature verification. | 2020-09-24 |
| Rell 0.10.2 | This release includes several features. Imports are now public by default, with no option for private imports. Specific definitions and wildcard imports can be specified, with support for import aliases and renaming. Namespaces can be split across multiple files. The REPL shell in the Rell interpreter allows for interactive evaluation of expressions, statements, and definitions. | 2020-02-26 |
| Rell 0.10.1 | This release includes several updates. The @external annotation replaces external blocks. Modules can now be marked as @external and imported as such. Abstract modules and functions allow for customization. The @omit annotation excludes fields from at-expressions. Sorting now uses @sort and @sort_desc. Enum value attributes can be used in at-expressions. New exists() and empty() functions for collections. Run-time errors include detailed stack traces. System queries provide version, build, and application structure information. Run.XML format changes include updates to blockchain RID and dependency specifications. | 2019-12-10 |
| Rell 0.10.0 | This release includes major updates. A new module system replaces the old "include" directive, allowing modules to import each other and be organized in directories. Classes are renamed to entities and records to structs, with a migration tool available for code updates. The @mount annotation specifies arbitrary mount names for definitions. Annotation syntax is updated to be more consistent. Anonymous namespaces allow applying annotations to multiple definitions. Name inference is improved to support qualified type names. Tuple field access by index is now supported. The compiler can report multiple errors. A new sha256() function for byte_array is added. Deprecated functions are now fully removed, with a migration tool to assist in updating code. | 2019-11-04 |
| Rell 0.9.1 | This release introduces a new decimal type for handling real numbers with high precision. The decimal type supports up to 131072 digits before the decimal point and 20 digits after. It includes global functions for conversion and basic operations, member functions for advanced operations, and constants defining precision and range. The integer.signum() function has been deprecated in favor of integer.sign(). | 2019-08-30 |
| Rell 0.9.0 | This release includes an upgrade to Postchain 3.0, renames GTXValue to gtv, and adds the virtual<T> type for data structure verification. It introduces the ?? null check operator, namespace support for operations and queries, and standardized function names. New functions for decimal and byte_array operations, improved Gtv conversions, and cryptographic functions are included. Integer operations now throw exceptions on overflow, and a new rowid type allows database primary key access. The run.xml format simplifies multi-chain configuration. | 2019-07-24 |
| Rell 0.8.0 | This release brings in several updates, including the include directive for importing files, support for namespaces for organizing definitions, and the addition of external block functionality for accessing classes from other blockchains. It introduces the when statement for conditional logic, tuple unpacking, and implicit casting for nullable variables. The release also adds increment/decrement operators, enforces checks for uninitialized variables, and allows late initialization of val variables. Additionally, it introduces new library functions, changes table naming conventions, updates configuration paths, and fixes slow compilation issues. | 2019-05-08 |
| Rell 0.7.0 | This release adds singleton object classes, enum types, and expression support for if. Updates and deletes now use cardinality operators and a simplified syntax.

The chain_context includes new configuration options, and table names are prefixed by blockchain ID to prevent conflicts. | 2019-02-20 |
| Rell 0.6.1 | This release includes updates such as requiring .. to access class attributes in @-expressions, replacing = with == for equality checks, and using = for named tuple fields. New record types and functions are introduced, along with GTXValue for encoded data. GTX-compatible parameters/results and new reference comparison operators (=== and !==) are added. Immutable types are now the only option for map keys or set elements, and class declaration order no longer affects cyclic records and complex structures. | 2018-12-21 |
