v0.18.1

This is the final release of this project. The dqlite team has discontinued maintenance of libraft, choosing instead to incorporate its source code into dqlite as a private implementation detail. We regret any inconvenience caused by this change.

If you depend on dqlite but not on raft directly, check the dqlite repository for up-to-date information about how to use dqlite's bundled raft build configuration. If you previously depended on dqlite's raft, you should switch to the maintained fork cowsql/raft.

v0.18.0

This release includes bug fixes and refactorings, with no new major features.

v0.17.1

This release includes some breaking changes to the raft.h API; these were made with forward-compatibility in mind, so we expect to be able to avoid such breaking changes in the future. See #303.

In addition, this release fixes some longstanding bugs in libraft:

• Correcting the quorum calculation that determines when it's safe to apply a log entry: #336
• Ensuring that a "known good" configuration is always available to roll back to when a new configuration can't be committed: #354

Other miscellaneous bug fixes are also included, addressing potential crashes when a Raft state transition occurs during an asynchronous operation like writing to disk.

v0.16.0

• Add support for hostnames, see #298 and linked PR's.
• Bugfixes

v0.15.0

• raft_io version 2 introducing async_work
• raft_fsm version introducing snapshot_async
• disable failing test for libuv 1.44.2 and higher

v0.14.0

• Support for automated recovery of corrupt segments upon startup. When detecting a corrupt segment, raft will rename the segment to corrupt-{timestamp}-{original-name} and attempt to start again, once. This behaviour can be disabled with raft_uv_set_auto_recovery.
• Support for raft_uv_tcp_set_bind_address.
• Deprecate raft_fixture_init, use raft_fixture_initialize combined with raft_fixture_grow.
• Bugfixes.

v0.13.0

• move to raft_fsm v2 introducing snapshot_finalize. snapshot_finalize, if not NULL this is run after a successful call to snapshot and must be used to cleanup state introduced by snapshot a.o. freeing allocated memory, releasing locks, etc. If snapshot_finalize is set, raft is no longer an owner of the raft_buffer array returned by snapshot.
  This change unfortunately breaks binary compatibility and builds libraft.so.2 instead of libraft.so.0.

• bugfixes

v0.11.3

Bugfix release.

v0.11.2

Bugfix release.

v0.11.1

• By default, the libuv implementation of raft will use lz4 to compress snapshots. This feature can be disabled with --disable-lz4 in the configure step.
• Minor bugfixes.
