- If math is used with the same selector multiple times, it will now act as a selector rather than an aggregate. See [#9563](https://github.com/influxdata/influxdb/pull/9563) for details.
- The default logging format has been changed. See [#9055](https://github.com/influxdata/influxdb/pull/9055) and [#9066](https://github.com/influxdata/influxdb/pull/9056) for details.

You can no longer specify a different `ORDER BY` clause in a subquery than the one in the top level query. This functionality never worked properly, but was not explicitly forbidden.
As part of the ongoing development of the `tsi1` index, the implementation of a Bloom Filter, used to efficiently determine if series are not present in the index, was altered in [#8857](https://github.com/influxdata/influxdb/pull/8857). While this significantly increases the performance of the index and reduces its memory consumption, the existing `tsi1` indexes created while running previous versions of the database are not compatible with 1.4.0.
2. Remove all `index` directories on databases using the `tsi1` index. With default configuration these can be found in `/var/lib/influxdb/data/DB_NAME/RP_NAME/SHARD_ID/index` or `~/.influxdb/data/DB_NAME/RP_NAME/SHARD_ID/index`. It's worth noting at this point how many different `shard_ids` you visit.
3. Run the `influx_inspect inmem2tsi` tool using the shard's data and WAL directories for -datadir and -waldir, respectively. Given the example in step (2) that would be `influx_inspect inmem2tsi -datadir /var/lib/influxdb/data/DB_NAME/RP_NAME/SHARD_ID -waldir /path/to/influxdb/wal/DB_NAME/RP_NAME/SHARD_ID`.
4. Repeat step (3) for each shard that needs to be converted.
Users with existing `tsi1` shards, who attempt to start version 1.4.0 without following the above steps, will find the shards refuse to open, and will most likely see the following error message:
-`parse-multivalue-plugin` was added with a default of `split`. When set to `split`, multivalue plugin data (e.g. df free:5000,used:1000) will be split into separate measurements (e.g., (df_free, value=5000) (df_used, value=1000)). When set to `join`, multivalue plugin will be stored as a single multi-value measurement (e.g., (df, free=5000,used=1000)).

When enabled, each time a continuous query is completed, a number of details regarding the execution are written to the `cq_query` measurement of the internal monitor database (`_internal` by default). The tags and fields of interest are
- The top-level config `bind-address` now defaults to `localhost:8088`. The previous default was just `:8088`, causing the backup and restore port to be bound on all available interfaces (i.e. including interfaces on the public internet).
-`max-body-size` was added with a default of 25,000,000, but can be disabled by setting it to 0. Specifies the maximum size (in bytes) of a client request body. When a client sends data that exceeds the configured maximum size, a `413 Request Entity Too Large` HTTP response is returned.
-`query-stats-enabled` was added with a default of `false`. When set to `true`, continuous query execution statistics are written to the default monitor store.

This release introduces a major new querying capability in the form of sub-queries, and provides several performance improvements, including a 50% or better gain in write performance on larger numbers of cores. The release adds some stability and memory-related improvements, as well as several CLI-related bug fixes. If upgrading from a prior version, please read the configuration changes in the following section before upgrading.
### Configuration Changes
The following new configuration options are available, if upgrading to `1.2.0` from prior versions.
-`security-level` which defaults to `"none"`. This field also accepts `"sign"` and `"encrypt"` and enables different levels of transmission security for the collectd plugin.
-`auth-file` which defaults to `"/etc/collectd/auth_file"`. Specifies where to locate the authentication file used to authenticate clients when using signed or encrypted mode.
The stress tool `influx_stress` will be removed in a subsequent release. We recommend using [`influx-stress`](https://github.com/influxdata/influx-stress) as a replacement.
- [#7723](https://github.com/influxdata/influxdb/pull/7723): Remove the override of GOMAXPROCS.
- [#7709](https://github.com/influxdata/influxdb/pull/7709): Add clear command to cli.
- [#7688](https://github.com/influxdata/influxdb/pull/7688): Adding ability to use parameters in queries in the v2 client using the `Parameters` map in the `Query` struct.
- [#7669](https://github.com/influxdata/influxdb/issues/7669): Uncomment section headers from the default configuration file.
- [#7650](https://github.com/influxdata/influxdb/issues/7650): Ensures that all user privileges associated with a database are removed when the database is dropped.
- [#7634](https://github.com/influxdata/influxdb/issues/7634): Return the time from a percentile call on an integer.
- [#7621](https://github.com/influxdata/influxdb/issues/7621): Expand string and boolean fields when using a wildcard with `sample()`.
- [#7616](https://github.com/influxdata/influxdb/pull/7616): Fix chuid argument order in init script @ccasey
[Go 1.7.4](https://golang.org/doc/devel/release.html#go1.7.minor) was released to address two security issues. This release includes these security fixes.
This release is built with go 1.7.3 and provides many performance optimizations, stability changes and a few new query capabilities. If upgrading from a prior version, please read the configuration changes below section before upgrading.
The admin interface is deprecated and will be removed in a subsequent release. The configuration setting to enable the admin UI is now disabled by default, but can be enabled if necessary. We recommend using [Chronograf](https://github.com/influxdata/chronograf) or [Grafana](https://github.com/grafana/grafana) as a replacement.
-`enabled` now default to false. If you are currently using the admin interaface, you will need to change this value to `true` to re-enable it. The admin interface is currently deprecated and will be removed in a subsequent release.
-`max-values-per-tag` was added with a default of 100,000, but can be disabled by setting it to `0`. Existing measurements with tags that exceed this limit will continue to load, but writes that would cause the tags cardinality to increase will be dropped and a `partial write` error will be returned to the caller. This limit can be used to prevent high cardinality tag values from being written to a measurement.
-`cache-max-memory-size` has been increased to from `524288000` to `1048576000`. This setting is the maximum amount of RAM, in bytes, a shard cache can use before it rejects writes with an error. Setting this value to `0` disables the limit.
-`cache-snapshot-write-cold-duration` has been decreased from `1h` to `10m`. This setting determines how long values will stay in the shard cache while the shard is cold for writes.
-`compact-full-write-cold-duration` has been decreased from `24h` to `4h`. The shorter duration allows cold shards to be compacted to an optimal state more quickly.
- [#7496](https://github.com/influxdata/influxdb/pull/7496): Filter out series within shards that do not have data for that series.
- [#7495](https://github.com/influxdata/influxdb/pull/7495): Rewrite regexes of the form host = /^server-a$/ to host = 'server-a', to take advantage of the tsdb index.
- [#7099](https://github.com/influxdata/influxdb/pull/7099): Implement text/csv content encoding for the response writer.
- [#6992](https://github.com/influxdata/influxdb/issues/6992): Support tools for running async queries.
- [#6962](https://github.com/influxdata/influxdb/issues/6962): Support ON and use default database for SHOW commands.

-`max-series-per-database` was added with a default of 1M but can be disabled by setting it to `0`. Existing databases with series that exceed this limit will continue to load but writes that would create new series will fail.
- Config option `[cluster]` has been replaced with `[coordinator]`
- Support for config options `[collectd]` and `[opentsdb]` has been removed; use `[[collectd]]` and `[[opentsdb]]` instead.
- Config option `data-logging-enabled` within the `[data]` section, has been renamed to `trace-logging-enabled`, and defaults to `false`.
- The keywords `IF`, `EXISTS`, and `NOT` where removed for this release. This means you no longer need to specify `IF NOT EXISTS` for `DROP DATABASE` or `IF EXISTS` for `CREATE DATABASE`. If these are specified, a query parse error is returned.
- The Shard `writePointsFail` stat has been renamed to `writePointsErr` for consistency with other stats.
With this release the systemd configuration files for InfluxDB will use the system configured default for logging and will no longer write files to `/var/log/influxdb` by default. On most systems, the logs will be directed to the systemd journal and can be accessed by `journalctl -u influxdb.service`. Consult the systemd journald documentation for configuring journald.

v0.11.1 [2016-03-31]
--------------------
### Bugfixes
- [#6168](https://github.com/influxdata/influxdb/pull/6168): Remove per measurement statsitics
- [SHOW SERIES output has changed](https://github.com/influxdata/influxdb/pull/5937). See [new output in this test diff](https://github.com/influxdata/influxdb/pull/5937/files#diff-0cb24c2b7420b4db507ee3496c371845L263).
- [SHOW TAG VALUES output has changed](https://github.com/influxdata/influxdb/pull/5853)
- JSON write endpoint is disabled by default and will be removed in the next release. You can [turn it back on](https://github.com/influxdata/influxdb/pull/5512) in this release.
- b1/bz1 shards are no longer supported. You must migrate all old shards to TSM using [the migration tool](https://github.com/influxdata/influxdb/blob/master/cmd/influx_tsm/README.md).
- On queries to create databases, retention policies, and users, the default behavior has changed to create `IF NOT EXISTS`. If they already exist, no error will be returned.
- On queries with a selector like `min`, `max`, `first`, and `last` the time returned will be the time for the bucket of the group by window. [Selectors for the time for the specific point](https://github.com/influxdata/influxdb/issues/5926) will be added later.

v0.10.3 [2016-03-09]
--------------------
### Bugfixes
- [#5924](https://github.com/influxdata/influxdb/issues/5924): Missing data after using influx\_tsm
- [#5716](https://github.com/influxdata/influxdb/pull/5716): models: improve handling of points with empty field names or with no fields.
This release now uses the TSM storage engine. Old bz1 and b1 shards can still be read, but in a future release you will be required to migrate old shards to TSM. For new shards getting created, or new installations, the TSM storage engine will be used.
This release also changes how clusters are setup. The config file has changed so have a look at the new example. Also, upgrading a single node works, but for upgrading clusters, you'll need help from us. Sent us a note at contact@influxdb.com if you need assistance upgrading a cluster.

- To store data points as integers you must now append `i` to the number if using the line protocol.
- If you have a UDP input configured, you should check the UDP section of [the new sample configuration file](https://github.com/influxdata/influxdb/blob/master/etc/config.sample.toml) to learn how to modify existing configuration files, as 0.9.3 now expects multiple UDP inputs.
- Configuration files must now have an entry for `wal-dir` in the `[data]` section. Check [new sample configuration file](https://github.com/influxdata/influxdb/blob/master/etc/config.sample.toml) for more details.
- The implicit `GROUP BY *` that was added to every `SELECT *` has been removed. Instead any tags in the data are now part of the columns in the returned query.
