v0.1.0

v0.1.0

Bug fixes:

• REP-6873: Handle a “nil” resume token on startup.
• Prevent logs from missing changes that happen “between” generations.
  (This is purely a logging fix.)
• Prevent /progress from reporting 0 tasks for generation 0.

New features:

• REP-6797: The metadata can now be stored on a standalone mongod.
  (Previously replication was required, even for a single node.)
• Logs now track mismatch “duration”, i.e., the amount of time that
  has passed when a mismatch remains. This helps to highlight
  mismatches prior to cutover.
• Logs now show the optime of the latest change event whose recheck
  has been completed. This gives an at-a-glance indicator of Verifier’s
  progress relative to both source & destination cluster times.
• Verifier can now track changes by reading the oplog rather than
  using a change stream. Reading the oplog is generally faster but
  carries some important caveats. See documentation.

v0.0.13

v0.0.13

• Fix a panic when failing to load resume token.
• Ignore MongoDB-internal databases.
• Update x/crypto.

v0.0.12

v0.0.12

• REP-6832: This fixes document fetches always to use the cluster’s most
  recently-seen timestamp, and to use majority read concern. Previously
  document fetches used local read concern and sent only the start time
  as the afterClusterTime, which allowed stale or not-majority-committed
  data to be used in comparisons.

v0.0.11

v0.0.11

• REP-6804 (BUG FIX): This fixes potential skipped rechecks after a mismatch.

v0.0.10

v0.0.10

• REP-6785 (BUG FIX): This prevents skipped documents across a restart
  of the verifier.
• Verification is now uses CPU and metadata much more efficiently.
  This allows verification of migrations that previously exceeded
  the verifier’s abilities.
• Single-node connection strings now default to a direct connection.

v0.0.9

v0.0.9

This release fixes a recently-introduced bug that caused a failure on
startup if srcURI or dstURI were specified in a config file but not as
command arguments.

v0.0.8

v0.0.8

• BUG FIX: Statistics aggregation failed when a recheck included collection
  metadata.
• Add basic time-series support. See documentation for important caveats.

v0.0.7

v0.0.7

• BREAKING CHANGE: Replace the --debug parameter with --logLevel.
• Add a --start CLI parameter.
• Reduce generation-end pause.
• Add a download script.
• Optimize change stream reading.
• Move a few overly-prolix log messages to trace-level.
• Various small improvements.

v0.0.6

v0.0.6

This release optimizes the handling of change streams. These changes will
help verification to keep pace with cluster writes.

v0.0.5

v0.0.5

• REP-6438: Logs now reflect progress made in currently-running tasks.
• REP-6492: Partitioning will now, when possible, use an algorithm that
  divides collections more evently.
