[charles-cooper]

meta issue to keep track of 0.4.0 issues

features:

• library modules VIP: Library Modules #2431
• stateful modules VIP: stateful singleton modules with ownership hierarchy #3722
  • improve initializer list hint fix[ux]: error messages relating to initializer issues #3831
• .vyi files VIP: .vyi files #2814
• vyper.interfaces -> ethereum.ercs VIP: move builtin interfaces to ethereum.ercs #3675
  • add warning/more helpful error message for usages of vyper.interfaces
  • move builtin interfaces to IERC20, IERC721, etc #3796
• remove named reentrancy locks VIP: remove named reentrancy locks #3760
• allow convert() to shorten bytestrings feat[lang]: allow downcasting of bytestrings #3832
• new await (or call) syntax for external calls VIP: syntactic distinction for external vs internal calls #2856
• floordiv operator VIP: ban div operator for integers in favor of floordiv #2847
• ban use of raw self (use self.address!), OR make interfaces interchangeable with address VIP: disallow the use of self as an address #3701 (comment)
• fix bytestring length inference
  • (related:) make bytestrings use ellipsis in all interfaces
• update struct constructor syntax -- use kwargs instead of dict VIP: Convert Struct construction to use kwargs #2381 (comment)
• rename enum to flag VIP: rename enum to flags #3642
• change ABI for decimals feat[lang]!: change ABI type of decimal to int168 #3696
• auto-export events which are logged in a contract fix: allow referencing events from interfaces #2852 (comment)
• create_from_blueprint default offset feat: default code offset = 3 #3454
• add length inference to dynarrays
• add exports: functionality feat[lang]: implement function exports #3786
• export bundles feat[lang]: implement export bundles #3698 -- DEFERRED TO 0.4.1

bugfixes: analysis

• fix purity analysis of exprs (ex. Calls to functions with higher mutability not prevented #3161)
• fix analysis of iterators fix: iterator modification analysis #3764
• implements mutability bug payable decorator in interface functions not enforced by implements #3774

bugfixes: codegen

• concat buffer overflow concat builtin can overrun memory #3737
• signed array indexes negative array indexes #3762
• slice bounds check invalid bounds check for slice() #3756

integration (compiler output):

• add __init__() to source map DEFERRED
• fix storage slot layout for large slots (use strings, ints get truncated)
• refactor storage layout refactor[tool]: refactor storage layout export #3789
• feat[tool]: archive format #3891

internal API:

• protect all CompilerData methods with anchor_evm_version

Could we maybe squeeze in #3607

Could we maybe squeeze in #3607

hm yea, need to think more on this, it's weird to have different default semantics for different functions

closing as finished with the 0.4.0 release
