[Unreleased]

Added

• Support for compilation pipeline going through the Yul intermediate representation

[0.35.0] - 2021-11-12

Added

• The output from dapp build now uses color to differentiate warnings and errors

• Support for solc 0.8.9/0.8.8

• dapp snapshot and dapp check-snapshot commands to snapshot test gas usage.

Changed

• Dapp remappings ignores non-directories in DAPP_LIB

Fixed

• Dapp can correctly parse replay strings from invariant tests
• Libraries are properly linked when compiling with solc >= 0.7

[0.34.1] - 2021-09-08

Added

• DAPP_TEST_DEPTH env var to control --depth
• --coverage flag for dapp test to generate coverage via hevm
• dapp debug respects the DAPP_LINK_TEST_LIBRARIES environment variable.
• dapp install accepts URLs with git tags, branches or revs specified as <url>@<tag>

Changed

• Dapp debug respects DAPP_LINK_TEST_LIBRARIES

Fixed

• Fix quotation bug in dapp replay

[0.34.0] - 2021-08-03

Changed

• hevm bumped to london hard fork.
• dapp --use now uses the solc binaries from https://binaries.soliditylang.org/ instead of the versions built from source via nix
• dapp remappings now issues a warning instead of failing with a hard error in case of mistmatched package versions in the dependency tree

[0.33.0] - 2021-07-01

Added

• A new type of test has been added: invariant testing, which runs a test function against a random reachable contract state. More information in the README
• A new flag for dapp test, --ffi allows users to enable the ffi() cheatcode in their tests

Changed

• solc 0.8.6 is now the default compiler version
• updated nixpkgs to the 21.05 channel

[0.32.2] - 2021-03-22

Changed

• updated nixpkgs to the 20.09 channel

[0.32.1] - 2021-02-02

Added

• support for (non-static) solc 0.7.4 and solc 0.8.1

Fixed

• dapp init works with the new standard-json architecture
• dapp verify-contract works with the new standard-json architecture

[0.32.0] - 2021-01-26

Changed

• dapp build, dapp test, dapp --make-library-state, dapp create now use solidity output generated via --standard-json instead of --combined-json. Building via the old format is still possible via dapp build --legacy, but is considered deprecated and will be removed in future releases.

The standard json used by dapp build can be set using the environment variable: DAPP_STANDARD_JSON, and defaults to the result of dapp mk-standard-json.

• dapp --find-libraries no longer requires --extract: libraries do not need to be built to be found.

Added

• dapp mk-standard-json command to generate a standard json for setting Solidity compiler options. The settings can be tweaked using the following environment variables:
  • DAPP_REMAPPINGS (defaults to the result of dapp remappings)
  • DAPP_LIBRARIES (defaults to the result of dapp --find-libraries)
  • DAPP_BUILD_OPTIMIZE (defaults to false)

Removed

• SOLC_FLAGS. To modify the compiler settings, use a custom standard json and set the filename as argument to DAPP_STANDARD_JSON.

Fixed

• dapp create <contract> --verify now passes the qualified path to dapp verify-contract, as expected.

[0.31.1] - 2020-12-10

Added

• dapp --use can find solc versions in the nix store even if they are not present on PATH

Fixed

• Corrected help text for solc version installation

[0.31.0] - 2020-11-29

Changed

• dapp test --match now matches on file path and contract name, as well as test name
• dapp --use searches directly for binaries in your path, rather than using nix run, giving a significant speed boost.

[0.30.0] - 2020-10-31

Added

• Support for solc 0.6.8
• Support for setting solc by path. Use DAPP_SOLC=/path/to/bin or dapp --use /path/to/solc ... to use a custom solc.
• dapp test --cache for RPC caching, via hevm.

[0.29.0] - 2020-08-19

Added

• Support for solc 0.6.12 for linux

Fixed

• Support for libraries. To test a project which includes libraries you need to use:

DAPP_BUILD_EXTRACT=1 dapp test

[0.28.0] - 2020-07-13

Added

• Support for solc 0.6.7
• The json outputted by dapp build will now contain storage-layout, if the chosen solidity version allows.

Changed

• Support for solc 0.6.7
• Updated hevm to 0.40
• Updated geth to 1.9.10

Removed

• Support for git submodules (setzer, dai-cli, chief, terra)
• dapp pkg functionality - dapptools is now installed and upgraded as a Nix package only, without relying on git
• DAPPTOOLS environment variable, which was only needed to support the git-based workflow above

Deprecated

• dapp pkg subcommand is now a no-op, and will be removed in future versions.

0.27.0 - 2020-04-23

Added

• Integration with hevms new property based testing functionality. Any test with nonzero arguments will be interpreted as a property test whose arguments are randomly generated and run --fuzz-runs number of times.
• Support for solc 0.5.16
• Support for solc 0.6.0
• Support for solc 0.6.6

Changed

• --extract flag for dapp build no longer needed for using dapp create.
• dapp create will fail if it finds multiple contracts with same name, requiring full path instead.

0.26.0

Added

• Support for solc 0.5.15

Fixed

• dapp address and dapp create now returns checksummed addresses

Changed

• dapp address returns address with 0x prefix.
• Default to solc 0.5.15
• Since solc 0.5.15, shared libraries are not built anymore, which might break certain rare usecases

0.25.0 - 2019-08-02

Fixed

• Correctly load testnet snapshots which were saved with multiple accounts

Changed

• dapp address is now implemented in bash rather than depending on ethereumjs-util

0.24.0 - 2019-07-09

Added

• Support for solc 0.5.10

Changed

• Default to solc 0.5.10

0.23.0 - 2019-07-08

Changed

• Faster dapp build, with a single compilation pass. Consolidates solc output into a single out/dapp.sol.json, which may break some workflows. dapp build --extract can be used to extract .abi, .bin, .bin-runtime files from the json into out/.
• The version of hevm is now shown in dapp --version.

0.19.0 - 2019-05-09

0.18.1 - 2019-05-03

Fixed

• Revert the change to the output of dapp create, because it created problems when concatenating scripts.

0.18.0 - 2019-05-02

Changed

• The return value of dapp debug in case of error is 1, rather than -1
• Improved printing of the address of the deployed contract in dapp create

0.15.0 - 2019-03-04
