0.3.1

• Allows for the CFG module to work on any EVM contract. [ #59, #53 ]
• Patches loop detection to be more thorough. [ #56 ]
• Introduces the -c or --color-edges to the CFG module to colorize edges based on the JUMPI condition. This is useful for visualizing the flow of if statements. [ #59 ]
• Minor memory optimizations. [ #59 ]

0.3.0

• Introduces the cfg module, which generates the control-flow graph for contract bytecode. [ #46 ]
  • Documentation: wiki
  • Examples: wiki
• Workspace improvements for contributors. [ #47 ]
• Linting fixes & optimizations. [ #48, #50 ]
• Remove regex backtracing for loop detection. Switch to symbolic stack loop detection (thanks plotchy), which both improves runtime and removes the branch limit of 1000. [ #51 ]

  • Fully resolves #30

  • Runtime reduced significantly.

0.2.5

• Major decompilation optimizations, reducing runtime exponentially. [ #45 ]

0.2.4

• Fixes a panic on unwrapping invalid conditional. [ #40 ]
• Fixes event resolution. [ #43 ]

0.2.3

• Introduces the decompile library, which allows for use of heimdall-rs' decompile module in other rust projects. <@perama-v>
  • Documentation can be found in the wiki.

0.2.2

• Fixes an issue with unwrapping a None event when analyzing traces. [ #33 ]

0.2.1

• Limit branches to 1000 branches. This is a patch for backtrack limit exceeded, as well as infinite branch recursion. [ #30 ]
  • Requires further patching, but for now this will ensure all contracts can be partially decompiled. Functions will stop tracing for new branches when reaching the limit.
• Implement natspec comments for deubgging
  • Argument natspec include potential types, in order of confidence.

0.2.0

• Decompiled solidity output is enabled through optional flag --include-sol <@Jon-Becker>
• Multithreaded signature lookup <@Jon-Becker>
• Efficient event signature lookup <@danyalprout>

0.1.8

• Fixes dependency issues with unstable features on ethers

0.1.7

• This release includes improvements for bifrost, including:
  • New -B / --binary flag to install heimdall from a precompiled binary attached to each release.
