• JSON Schema for tact.config.json: PR #194

• The -h/--help, -v (short for --version), -p (short for --project), --func (for only outputting FunC code) and --check (for only doing the syntax and type checking) command-line flags: PR #287
• The mode enum in project properties of tact.config.json for specifying compilation mode: full (default), funcOnly (only outputs FunC code and exits), or checkOnly (only does the syntax and type checking, then exits): PR #287
• The foreach loop for the Map type: PR #106

Changed

• The implicit empty init function is now present by default in the contract if not declared: PR #167
• Support trailing commas in all comma-separated lists (struct instantiations, initOf arguments, init() parameters, inherited traits via with, function arguments and parameters): PR #179 and PR #246
• @stdlib/stoppable now imports @stdlib/ownable so the programmer does not have to do it separately: PR #193
• The newAddress function now evaluates to a constant value if possible: PR #237
• The pow power function could only be used at compile-time, but now it is available in the standard library and can be called both at runtime and compile-time: PR #267
• The dump() and dumpStack() functions now print the file path, line number, and column number in addition to the data: PR #271
• Use | instead of + for send mode flags because the bitwise OR operation is idempotent and hence safer: PR #274
• Bumped the versions of @ton/core and ohm-js to the most recent ones: PR #276
• Generated .pkg-files always use POSIX file paths (even on Windows): PR # 300
• The -p/--project flags now allow specifying more than one project name. Additionally, they also require a --config flag to be specified: PR #287
• Command-line interface now allows compiling a single Tact file directly, without specifying a config: PR #287

Fixed

• Escape backticks in error messages for generated TypeScript code: PR #192
• Integer overflows during compile-time constant evaluation are properly propagated as a compilation error: PR #200
• Incorrect "already exists" errors when using the toString and valueOf identifiers: PR #208
• Empty inherited trait lists after with keyword are now disallowed: PR #246
• Allow chaining method calls with !!, for instance, map.asCell()!!.hash() is grammatically correct now: PR #257
• Precedence levels for bitwise operators, equality and comparisons now matches common languages, like JavaScript: PR #265
• Incorrect variable scoping in the repeat, while and until loops: PR #269
• FunC compilation errors when trying to dump() values of the Cell, Slice, Builder and StringBuilder types: PR #271
• Tact's CLI returns a non-zero exit code if compilation fails: PR #278
• Use the most recent version of the FunC standard library stdlib.fc: PR #283
• The WASM version of the FunC compiler has been updated to 0.4.4 and patched to work on larger contracts: PR #297
• The return-statement reachability analysis: PR #302

• The SendBounceIfActionFail send mode constant to the standard library: PR #122

Changed

• Decimal and hexadecimal literals now allow underscores as numerical separators: PR #99

Release 1.1.3

Added

• bitwise and and or operations
• staticaly compile expressions with bitwise operations if possible

Release 1.1.2

Added

• Add full ABI in bindings

Release 1.1.1

Fixed

• Fix typescript bindings generation for custom key and value serialization formats
• Fix missing external messages in bindings

Release 1.1.0

⚡️ Breaking changes

• reply is now a method of Contract instead of global context and changed it's behaviour if storage reserve is non-zero in contract.
• Logical expressions are now calculated differently: && now does not execute right expression if left is false and || does not execute right expression if left is true. Before it was executed in any case. This change is made in attempt to reduce unexpected behaviour.
• OwnableTransferable is now sends response to the sender.
• overwrites was renamed to override
• Deployable trait now sends non-bounceable notifications instead of bounceable ones.

Features

• Address to Address maps
• Ability to define key and value serializations for maps
• sha256 hashing
• forward and notify functions that can be used to send messages to other contracts using remaining value of incoming message
• virtual and abstract constants that can be shared between traits
• storageReserve constant in every contract that can be used to reserve some storage space by any trait
• abstract functions that can be implemented in contracts
• FactoryDeployable trait for deploying from factory contract
• @stdlib/dns for easier DNS resolution
• Opt-in external message support
• Typed bounce receiver and bounce<T> type modifier
• commit for committing state changes
• inline modifier for functions for inlining them into the caller
• Ability to define empty messages (but not structs)
• Some string-related operations are now computed at compile time if possible

Fixed

• Signature of preloadBits function
• Fixed readForwardFee function
