v0.3.2

In case of the following error: [ERROR] Protostar <VERSION> is not compatible with provided protostar.toml.
Update the protostar_version in the protostar.toml to your Protostar version e.g.:

["protostar.config"]
protostar_version = "0.3.2"

(This change shouldn't be necessary. We had a bug in the deployment script introduced in v0.3.1.)

Changelog

• added handling of hexadecimal values in --inputs and --sign arguments in the deploy command, see #637
• added initial activity indicator when Protostar boots

and some internal improvements in preparation for new features to come!

v0.3.1 Minor improvements

• added config keyword argument to declare and deploy_contract migration cheatcodes
• added call migration cheatcode
• added protostar_version verification
• improved feedback messages
• changed testing default target to current working directory rather than test directory
• removed fuzz_simplification_runs

(This release includes many changes under the hood.)

v0.3.0 Fuzz testing & Migration scripts

• added fuzz testing
• added migration scripts and migrate command
• added declare command
• added --report-slowest-tests flag to the test command
• added support for configuring required arguments in the protostar.toml
• improved test collecting performance
• improved documentation structure
• improved testing output by adding test case execution time info
• updated cairo-lang version to 0.9.1
• removed --stdout-on-success flag
• removed limitation: test file can't import a file with a constructor expecting arguments
• removed fast-collecting flag from test command
• fixed data transformer for expect_events cheatcode when unit testing

v0.2.6 store/load cheatcodes, QoL

• added store and load cheatcodes, which modify any contract storage
• added exit-first flag to the test command, which interrupts testing when any test fails
• added stdout-on-success flag to the test command and improved handling of the standard output, which should improve debugging experience
• added fast-collecting flag to the test command, which enables faster but unsafe test collecting algorithm
• added no-progress-bar flag to the test command
• added upgrade checker, which displays an information when a new version of the Protostar is available
• added logging execution time
• improved performance of cheatcodes using data transformer
• improved context hint local used by __setup__ by allowing assigning any object
• fixed data transformer issues for contracts deployed in the __setup__ function
• removed account-contract flags from test and build commands — Protostar detects account contracts from now on

v0.2.5 fixes and resource usage info

• added resource usage information next to test case testing result 
• added --disable-hint-validation flag to the test command
• added --account-contract to enable compilation of contracts containing __execute__ function
• improved expect_events cheatcode by supporting data transformation
• fixed list assignment index out of range error
• fixed freezing issue in larger projects

v0.2.5 pre-release

• added account-contract flag
• added gas estimation per test case
• fixed performance issue in large projects

v0.2.4 declare, prepare, deploy

• added declare cheatcode
• added prepare and deploy cheatcodes to allow using other cheatcodes to test constructors
• improved mock_call and deploy_contract cheatcodes by integrating Starknet.py's data transformer
• improved handling of compilation errors in test files during collecting phase
• improved warp and roll cheatcodes to be usable in the integration testing approach
• changed deploy_contract to declare the contract before deploying
• fixed mock_call not affecting calls in contracts deployed by deploy_contract
• fixed SSL error when running upgrade command
• minor fixes and improvements
