entries:
- breaking: true
  highlights:
  - Note types declared inside a contract must be pub.
  - Noir v1.0.0‑beta.25 enforces the caller's visibility when comptime code resolves a trait method into a typed expression.
  - The sequencer skips building and proposing a checkpoint when p2p is enabled and it is connected to fewer than SEQ_MIN_PEERS_TO_PROPOSE peers
    (default 1).
  - JSON‑RPC internal errors now return code -32603 instead of -32600.
- breaking: true
  highlights:
  - History note nullification helpers renamed and restricted to own‑contract notes.
  - Old helpers have been renamed with a local_ prefix and now assert that the note belongs to the executing contract.
  - set_as_fee_payer now asserts it is called during the setup phase.
  - PXE stores are now selected by (l1ChainId, rollupAddress, schemaVersion) instead of being wiped on mismatch.
current_version: 5.2.0
note: Versioning scheme follows semantic versioning (major.minor.patch). Only the three most recent version sections (5.2.0, 5.0.1, 5.0.0) are
  listed, each containing up to four highlight sentences extracted directly from the migration notes page. 1 extracted row(s) were dropped because
  their quote was not on the page.
