Development Changelog

NB: The changelog for releases can be found at: https://tezos.gitlab.io/CHANGES.html

This file lists the changes added to each version of octez-node, octez-client, and the other Octez executables. The changes to the economic protocol are documented in the docs/protocols/ directory; in particular in docs/protocols/alpha.rst.

When you make a commit on master, you can add an item in one of the following subsections (node, client, …) to document your commit or the set of related commits. This will ensure that this change is not forgotten in the final changelog, which can be found in docs/CHANGES.rst. By having your commits update this file you also make it easy to find the commits which are related to your changes using git log -p -- CHANGES.rst. Relevant items are moved to docs/CHANGES.rst after each release.

Only describe changes which affect users (bug fixes and new features), or which will affect users in the future (deprecated features), not refactorings or tests. Changes to the documentation do not need to be documented here either.

General

  • Add and experimental switch to enable the use of the Brassaia context backend using TEZOS_CONTEXT_BACKEND=Brassaia environment variable. (MR :gl:`!13054`)
  • Removed binaries for Oxford. (MR :gl:`!13795`)
  • Removed binaries for ParisB. (MR :gl:`!14026`)

Node

  • Add an source argument to GET /chains/<chain>/mempool/pending_operations which allows operations to be filtered by source. (MR :gl:`!11278`)
  • Add an RPC /chains/<chain>/blocks/<block>/context/smart_rollups/smart_rollup/<sr1...>/consumed_outputs/<outbox_level> that returns the consumed output's indexes for the given outbox level. (MR :gl:`!12776`)
  • Restart the block application/peer validation once when encountering a context error to mitigate the error crashing by replaying the application/validation before raising an uncaught failure (MR :gl:`!13398` and :gl:`!13437`)
  • Importing a snapshot uses the configuration if it exists. It's useful when an archive snapshot contains some unsafe_pvm_patches. The same unsafe_pvm_patches must be set in the export and import or the import will fail. (MR :gl:`!13397`)
  • When available, add some colors to some event logs: (MR :gl:`!13610`)
    • node_is_ready is now Green
    • synchronization status changes are now Magenta
    • store merge start/end events are now Cyan
    • update to protocol table is now Blue
  • Removed Oxford mempool plugin. (MR :gl:`!13798`)
  • Remove support for deprecated version 0 for RPCs GET ../mempool/monitor_operations, POST ../helpers/preapply/operations, GET ../blocks/<block>, GET ../blocks/<blocks>/metadata. and GET ../blocks/<blocks>/operations. (MR :gl:`!13449`)
  • Remove support for deprecated version 1 for RPC GET ../mempool/pending_operations. (MR :gl:`!13449`)
  • Remove support for deprecated version 0 from RPCs POST ../helpers/parse/operations, POST ../helpers/scripts/run_operation and POST ../helpers/scripts/simulate_operation. (MR :gl:`!13451`)

Client

  • The --extra-big-maps and --other-contracts command-line parameters, which are used to specify contextual information in some Michelson-related commands, now allow file names as argument. (MR :gl:`!13311`)
  • Breaking change Removed read-write commands specific to Oxford. (MR :gl:`!13799`)
  • Breaking changes client's encoding with legacy attestation name are no longer supported starting from protocol following ParisC. (MR :gl:`!13454`)

Baker

  • When available, add some colors to some event logs: (MR :gl:`!13611`)
    • block_injected is now Blue
    • revealing_nonce is now Cyan
  • Branch used in consensus operation is now the grandparent block instead of the parent block. This is done to avoid having consensus operation branched on block that are not part of the canonical chain anymore.(MR :gl:`!13619`)

Accuser

  • When available, add some colors to some event logs: (MR :gl:`!13611`)
    • double_attestation_detected and double_preattestation_detected is now Magenta
    • double_attestation_denounced and double_preattestation_denounced is now Blue

Proxy Server

Protocol Compiler And Environment

  • Added a new version of the protocol environment (V13). (MR :gl:`!12966`)

Codec

Docker Images

Smart Rollup node

  • Updated RPC /local/batcher/injection with a new query argument possibility. When the rpc contains "drop_duplicate": true then the batcher will drop the messages that were already injected with a previous RPC call. If "drop_duplicate": false then the rollup node defaults to its the previous behavior, where messages are injected again, even if the exact same one was previously injected. By default "drop_duplicate": false. (MR :gl:`!13165`)
  • RPC /health now returns meaningful health related data to asses if the rollup node operates correctly. Old /health RPC is renamed to /ping. (MR :gl:`!12940`)
  • Use a local cache per game for intermediate states of dissections. (MR :gl:`!12899`)
  • Introduce the 5th version of the WASM PVM, which defaults to a higher tick limits to delegate refutability to the kernels. (MR :gl:`!12999`)
  • Trigger GC every 1000 blocks (instead of 100) by default to reduce CPU consumption. (MR :gl:`!13177`)
  • Default history mode is now "full". (MR :gl:`!13178`)
  • Allow to import archive snapshots in "full" rollup node. (MR :gl:`!13186`)
  • Fix a bug in how commitments are computed after a protocol migration where the the commitment period changes. (MR :gl:`!13588`)
  • Ensure penultimate commitment is published on snapshot export as a failsafe. (MR :gl:`!13544`)
  • Include commitment publication information in snapshots. (MR :gl:`!13724`)
  • Under-approximate publication level for cementation when it is missing. (MR :gl:`!13725`)
  • New metrics for the rollup node, including performance ones which can be enabled with the flag --enable-performance-metrics (requires lsof). (MR :gl:`!12290`)
