CDT 4.1.0 Release Notes
Release 4.1.0
This CDT release is required when compiling System Contracts for use with the Savanna Consensus algorithm used with release Spring 1.0. This release includes full support for BLS cryptography and managing BLS signatures.
In addition there are a number of usability features.
- Export memory from wasm file for use with Vert
- Supports MacOS with native linking
- BLS cryptography as a host function
The new host functions provided in CDT v4.1.0 and later are only compatible in Spring v1.0.0 and above. Running contracts which include new CDT v4.1.0 host functions will not execute in previously released Leap software. CDT v4.1.0 may still be used to compile and run contracts across both Spring and Leap when only pre-Spring host functions are used.
Note:
- Running full integration tests requires linking to Spring libraries. If no integration tests are needed, CDT may be build and installed independent from Spring.
- Changes from RC1 adding a test as described in PR #299
- Changes from RC2 resolve Indeterministic Build Output PR #308

CDT 4.0.1 Release Notes
Contract Development Toolkit (CDT) is a C/C++ toolchain targeting WebAssembly (WASM) and a set of tools to facilitate development of smart contracts written in C/C++ that are meant to be deployed to an Antelope blockchain.
This bug fix release fixes MacOS builds, updates integrations with Leap , and removes the previously unused "antler-proj" library.
Read on for details.
Bug Fixes
Updated CI tests to use libtester from Leap Package
Updates GitHub Actions to use libtester provided by existing leap deb package.
Add Explicit Overloads
Fixes a bug where std::basic_string<uint8_t> fails to correctly match in datastream for the stream operators
Fix Deprecated Call in cmake
Updates cmake to use find_package(Python) previous method is deprecated.
Fix MacOS Builds
Updates codes to work on the latest clang, and updated linking to work across MacOS and Linux.
PRs
- (223)[4.0] fix
-fnativelinking on macOS @spoonincode - (233)[4.0] remove
is_callable_v<>workaround, fixing build @spoonincode
Remove Unused Libraries
Removes Antler Run and Antler Proj. This code was unaccessible.
Fix ABI Issues with Nested Contract Calls
The wrong type was included in an ABI. This occured in limited circumstances, when including an hpp file from a contract that defined a global singleton into another contract. In this scenario CDT incorrected added the global table to the ABI.

ANTLER Project Tools (antler-proj) is a set of tools to help in the generation of smart contracts intended for deployment to an Antelope blockchain.
This set of tools will help the developer create, maintain, build, and test smart contracts.
Usage
For now, please see the User Guide for usage.
Additional crypto primitive host functions
Additional crypto extensions support is now available. To see the scope of all primitives supported, view our documentation here.
In order to bring parity between asset and extended_asset for operators, the following were added:
extended_asset& operator*=(int64_t)extended_asset operator*(const extended_asset&, int64_t)extended_asset operator*(int64_t, const extended_asset&)int64_t operator/(const extended_asset&, const extended_asset&)extended_asset& operator/=( int64_t )extended_asset operator/( const extended_asset&, int64_t )
CDT was also missing support for the get_code_hash host function introduced with Antelope's GET_CODE_HASH protocol feature. The API wrapper for this has been added along with some additional testing.
Bug Fixes
Missing inline declaration on blake2_f intrinsics helper
blake2_f() in crypto_ext.hpp were not inline, so if multiple .cpp files included this header file duplicate symbol errors were being thrown.
Wrong table name for ABI when eosio::singleton used
Crash in cdt-cpp when using a std::basic_string<> in action wrapper
Other Changes
Tables with name typed primary key now supported
Using a name as a primary key in a table is a common use case. Support for this use case to the multi_index template has now been added.
Feature Lifecycle Updates
Removals in v4.0.0
boost removed from eosiolib and native libraries
boost library usage removed from eosiolib and native libraries. It still remains in cdt but deprecated as for now as part of cdt package. Usage of external to cdt boost for contracts development is not restricted.

CDT v3.1.0 Release Notes
Contract Development Toolkit (CDT) is a C/C++ toolchain targeting WebAssembly (WASM) and a set of tools to facilitate development of smart contracts written in C/C++ that are meant to be deployed to an Antelope blockchain.
This release, includes additional crypto extensions for crypto primitives host functions, an update to how data segments are partitioned, and documentation updates.
Read on for details.

Crypto Extensions
TypesG1 point G2 point have been added to use as input and as results for computations and the bigint type has been added to modexp.
Data segment partitioning updates
There is now a new optimization to run on data segments that will repartition the data segments with fracturing taking place at 1024 bytes maximum and when lengths of spans of zeros are present.

There is now a new optimization to run on data segments that will repartition the data segments with fracturing taking place at 1024 bytes maximum and when lengths of spans of zeros are present.

CDT v3.0.1 Release Notes
This patch release contains a bug fix, an enhancement, and documentation updates.
Read on for details.
Bug fixes
Inconsistency in ABI generated for map
In CDT releases prior to 3.0.0, the ABI generated for std::map<K,V> was a list of structs in which the ABI for the inner struct included fields first and second, which is the same ABI that would be generated for std::pair<K,V>.
In CDT 3.0.0, the behavior of ABI generation for std::map<K,V> unintentionally changed such that the inner struct would sometimes use the fields key and value instead (depending on whether a std::map<K,V> or std::pair<K,V> was encountered first in the code scanned by the ABI generator). Additionally, if the ABI generation chose the version of the struct with fields key and value for the inner struct generated from a std::map<K,V>, then all other types involving std::pair<K,V> for different fields in the ABI would also use that version of the struct with fields key and value as opposed to version containing first and second that was intended.
This release fixes the bug introduced in CDT 3.0.0 to ensure that the inner struct generated in the ABI for std::map<K,V> is always the version that is compatible with the intended ABI of std::pair<K,V>: the version that contains first and second fields.
Enhancements
Make varints compile-time constructible
The varints unsigned_int and signed_int have been updated to be compile-time constructable to be available for compile time constant expressions.
