v0.7.2

Changes

• Simplify fetch hostcall case 8: fetch only authorizer config blob (GP #486)
• Fix accumulation statistics to include services accumulated forfree or due to transfers (GP #484).
• PVM Invocations: Correct gas charge for transfer host call failures (GP #488)
• Fix max size of concatenated variable-size blobs, extrinsics and imported segments of a work package.
  (GP #493)

v0.7.1

CHANGES

• Remove on_transfer from service statistics (GP #457)
• Serialization: Include version byte prefix for accounts (GP #472)
• Registrar service privilege (GP #473)
• Add preimage provision status to the Accounts structure of accumulate StfState (see ASN.1 syntax).

DEVIATIONS

• Accumulation statistics for services accumulation are updated according to version 0.7.2.
  In 0.7.2, service stats need to be updated when any service accumulation logic has been executed.

v0.7.0

CHANGES

• Serialization: Move all variable-length items to end of encoding (GP #418)
• Rearrange the items in CoreActivityRecord and ServiceActivityRecord, refer to the ASN.1 schema and GP (no explicit GP PR).

DEVIATIONS

• gavofyork/graypaper#480 (Unreleased)

New TINY constant

• $G_T$ ( max per block gas ) for tiny spec fixed to 20_000_000 (ref JamBrains/jam-docs#59)

v0.6.7

• Rearrange the inner PVM page admin (GP #402)
• PVM pages can change access without clearing (GP #404)
• Renumber host-calls (GP #408)
• info host call uses fixed length types (GP #410)
• Accounts storage deposit offset and additional metadata (GP #397 and #400)
• Core assignment privileges is a sequence, one item per core (GP #393)
• Most recent accumulation outputs are stored in state; Recent blocks history now stores
  the MMR roots only, the full MMR structure relative to the last accumulation is kept
  separately (GP #405)
• New bundle size limit (GP #407)

DEVIATIONS

Changes from version 0.7.0 that have already been incorporated

• gavofyork/graypaper#440 (since the beginning)
• gavofyork/graypaper#414 (since v0.6.6)
• gavofyork/graypaper#433

** Unreleased Changes**

• gavofyork/graypaper#480

v0.6.6

• Extended the fetch host call with new variants.
• Updated numeric identifiers used in fetch.
• Updated numeric identifiers for PVM errors.
• PVM wrangled operands changed.
• Removed the traces 000...000.bin/json step, as it was not a valid trace step and was intended to be handled specially for genesis. Since it shared the same format as regular trace steps, it could be ambiguous or misleading.
• Introduced an explicit genesis.bin file containing the genesis state and header.
• The authorizer trace field has been moved to the end of the accumulation operand encoding (C.29)

DEVIATIONS

fetch host call for protocol parameters ($\omega_{10}=0$) has been implemented according to this (currently) unreleased change: gavofyork/graypaper#414

For the fetch hostcall id we're still using 18 as per GP 0.6.6. The picked change only concerns the value returned for w_10=0
