Releases

v0.9.0​

Feature release targeting PISA v0.8.0. As PISA v0.8.0 supports storage costing, Coco supports specifying the payer for logic storage via payer keyword on mutate statement. Cocolab supports access control and few new syntax changes improve developer's experience.

Type: Minor Feature · PISA: v0.8.0 · Date: August 14, 2026

New (requires version = "0.8.0" under [target.pisa]):

  • payer clause on mutate — names who pays for the storage a logic-state write consumes (payer Logic, payer Sender, payer Actor(id); Sender is the default). Logic state only
  • Environment.StorageResult(account, payer) — returns the storage bytes added and removed in the current interaction, replacing the global VolumeCapacity() / VolumeAvailable() metering
  • Actor query methods Actor(id).Exists(), Actor(id).HasSigned() and Actor(id).Param(name)

New in Cocolab:

  • Storage access control — grant, get and wipe storage_mutate simulate an actor authorizing a logic to write their state, matching the default-deny enforcement of the PISA v0.8.0 runtime. Policies are kept in the session snapshot
  • Names are validated when a command runs: callers(...) may only name compiled logics and origins(...) only registered users, and every as <actor> clause — on the storage_mutate commands and on deploy/invoke/enlist/create — is rejected outright when it names nothing, instead of coming back as an empty result

Changes (all targets):

Breaking (all targets):

  • Every asset engine method now carries a required qualifier: writes are dynamic, reads are static. Asset logic written for 0.8.2, where transfer and approval endpoints carried no qualifier, needs the qualifiers added

Breaking on 0.8.0 targets:

  • Writing another actor's state is denied by default. mutate Module.Actor(id).* for anyone but the sender now requires that actor's storage_mutate grant; Module.Sender.* and Module.Logic.* writes and all reads are unaffected
  • Environment.VolumeCapacity() and Environment.VolumeAvailable() are not supported; use Environment.StorageResult()

v0.8.2​

Bug-fix release. Updates runtime to PISA v0.7.1.

Type: Bug-fix · PISA: v0.7.1 · Date: June 19, 2026

Changes:

  • Cocolab: persistent session state, configurable default.basefuel and per-call fuel, and events are printed even when an interaction fails
  • Fixed quoting of hex literals in generated YAML manifests
  • Fixed += on strings and bytes (now concatenates)
  • Fixed f-string handling of literal {{/}} braces and a brace at the end of an expression
  • Nested and brace-elided composite literals; omitted class fields default to their zero value
  • Interface endpoint qualifiers now propagate to the caller
  • Updated runtime to PISA v0.7.1
