For the full commit log, see here.

v0.8.1, release 2021-02-17

  • Ensure workers can send data popped off the queue at shutdown (#239, @onlynone)
  • Add support for special characters in password when using url keyword (#242, @swistak35)
  • Add Ruby 3.0 support (#249, @dentarg, @paul and @track8)
  • Support characters that need quoting for usernames and database names (#248, @estheruary)

v0.8.0, released 2020-02-05

  • Allow dropping of specific series from specific DBs (#233, @cantino)
  • Add support for MRI 2.7 (#235, @jeffkowalski)
  • Raise a LineProtocolError if attempting to write empty values as field set is required. This adds descriptive feedback to the error "unable to parse '{series},{tags} ': invalid field format" (#236, @todtb)
  • Add support for configuring HTTP Proxy (#238, @epchris)

v0.7.0, released 2019-01-11

  • Drop support for Ruby 2.2, since Bundler dropped it and we want to use Bundler in the development cycle as well.
  • Fix issue with tag values ending in a backslash.

v0.6.4, releases 2018-12-02

  • Fix newly introduced InfluxDB.now(precision) for precisions larger than "s".

v0.6.3, released 2018-11-30

  • Added InfluxDB.now(precision) and InfluxDB::Client#now as companions to InfluxDB.convert_timestamp.

v0.6.2, released 2018-11-30

  • Added InfluxDB.convert_timestamp utility to convert a Time to a timestamp with (taken from PR influxdb-rails#53 by @ChrisBr).

v0.6.1, released 2018-08-23

  • Fix InfluxDB::Client#delete_retention_policy: the database name argument is now quoted (#221, #222 @AishwaryaRK).
  • Add InfluxDB::Client#list_measurements and #delete_measuerment (#220)

v0.6.0, released 2018-07-10

  • Add batch query support via InfluxDB::Client#batch (and using InfluxDB::Query::Batch). Using multiple queries joined with ; will cause issues with Client#query in combination with either GROUP BY clauses or empty results, as discussed in #217.

    Initial code and PR#218 from @satyanash.

v0.5.3, released 2018-01-19

  • Fix NoMethodError in InfluxDB::Client#list_retention_policies when the database has no RPs defined (#213, @djoos)

v0.5.2, released 2017-11-28

  • Add async option to block on full queue (#209, @davemt)

v0.5.1, released 2017-10-31

  • Add support for SHARD DURATION in retention policy (#203, @ljagiello)

v0.5.0, released 2017-10-21

  • Add support for precision, retention policy and database parameters to async writer (#140, #202 @rockclimber73)

    Attention You may need to validate that your calls to the write API (InfluxDB::Client#write, #write_point, #write_points) don't accidentally included a precision, RP, and/or database argument. These arguments were ignored until now. This is likely if you have changed your client instance configuration in the past, when you added a async: true. Updating might cause data inconsistencies!

v0.4.2, released 2017-09-26

  • Bugfix in InfluxDB::PointValue: Properly encode backslashes (#200)

v0.4.1, released 2017-08-30

v0.4.0, released 2017-08-19

  • Dropped support for Ruby < 2.2.
  • Updated dependencies.
  • Refactor some method declarations, to take kwargs instead of an options hash (this shouldn't break call sites).
  • Allow configuration by an URL (idea by @carlhoerberg in #188).
  • Improved logging (#180).

v0.3.17, released 2017-09-27

  • (Backport from v0.4.1) Bugfix in async client: Flush queue before exit (#198, #199 @onlynone)
