## Releases

### v3.10.0 — v3.10.0 | 06-17-26

- Date: 2026-06-17
- Version: v3.10.0
- Original notes: https://github.com/influxdata/influxdb/releases/tag/v3.10.0
- Permalink: https://whatsnew.fyi/product/influxdb/releases/v3.10.0

- **added** — Catalog v3 automatically migrates to a compact binary format on first startup, reducing catalog size by approximately 5–6x compared to v2
- **added** — Processing engine supports cross-database queries via the `database=` keyword argument on `influxdb3_local.query()`
- **added** — Processing engine has trigger lockdown with new serve flags `--restrict-plugin-triggers-to` and `--plugin-dir-only` to restrict plugin behavior
- **added** — GET /ready endpoint returns 200 OK when the server can reach object storage and 503 when it cannot
- **added** — Always-on heap profiling enabled at startup with negligible overhead accessible at the pprof endpoint
- **added** — influxdb3 debug catalog command allows inspecting catalog state offline directly from object storage without a running server
- **added** — Row-level deletion via `influxdb3 delete rows` command to delete rows by time range and tag predicates, monitored with the `system.row_deletes` table
- **added** — Backup and restore management via `influxdb3 create/status/show/delete/cancel backup` and `restore` commands plus matching `/api/v3/enterprise/backup` and `/restore` endpoints
- **added** — Bulk import of generic Parquet files with `influxdb3 import upload` command mapping columns to InfluxDB types
- **added** — User authentication and RBAC with username/password to JWT conversion, optional OAuth/OIDC, and three built-in roles (Admin, Auditor, Member)
- **added** — 36 new `influxdb3_compactor_*` Prometheus metrics including `influxdb3_compactor_snapshot_lag_seconds` as the primary health signal
- **changed** — Object-store licenses are no longer bound to object-store config allowing bucket or store migration with the same license
- **changed** — `--pt-partition-count` flag renamed to `--pt-shard-count` with no alias
- **changed** — `/api/v2/write` endpoint now returns 403 for valid tokens lacking write permission instead of 401
- **changed** — Line-protocol parse errors on `/api/v2/write` now return 400 instead of 500
- **fixed** — Compaction stability improvements including ingest-time, deadlock, write-amplification, and gen1 orphaning fixes

The following are some highlighted updates with the newest release for InfluxDB 3 Core and Enterprise. Learn more via our full [Release Notes](https://docs.influxdata.com/influxdb3/core/release-notes/).

##### InfluxDB 3 Core Updates

**Catalog v3**: The on-disk catalog automatically migrates to a compact binary format (~5–6x smaller than v2) on first startup. Migration is automatic, idempotent, and crash-safe. **Back up** `{prefix}/catalogs/` and `{prefix}/_catalog_checkpoint` before upgrading; the migration is one-way and 3.9.x binaries _cannot_ read a v3 catalog.

**Processing engine supports cross-database queries**: Plugins can now read from any database using the `database=` keyword argument on `influxdb3_local.query()`.

**Processing engine now has trigger lockdown**: New serve flags restrict plugin behavior; `--restrict-plugin-triggers-to` limits triggers to `wal`, `schedule`, or `request`, and `--plugin-dir-only`

**`GET /ready` endpoint**: Returns `200 OK` when the server can reach object storage, `503` when it cannot; ideal for load balancer and orchestration readiness probes.

**Always-on heap profiling**: Enabled at startup with negligible overhead (~<1% CPU), accessible at the existing pprof endpoint. Disable with `MALLOC_CONF=prof:false`.

**`influxdb3 debug catalog`**: Inspect catalog state offline directly from object storage; no running server required.

##### InfluxDB 3 Enterprise Updates

All Core updates are included in Enterprise. The following are exclusive to Enterprise. Many of these require the new performance update preview (in beta); if using these features, they should not be included in production environments yet. 

**Row-level deletion**: Delete rows by time range and tag predicates with `influxdb3 delete rows`. Deletion is asynchronous and applied by the compactor. Monitor with the `system.row_deletes` table. Requires `--use-pacha-tree`.

**Backup and restore**: Full backup and restore management via new `influxdb3 create/status/show/delete/cancel backup` and `restore` commands, plus matching `/api/v3/enterprise/backup` and `/restore` endpoints. Requires `--use-pacha-tree` and a compactor node with an admin token.

**Bulk import**: Import generic (non-IOx) Parquet files with `influxdb3 import upload`, mapping columns to InfluxDB types via `--column` flags. Track jobs with `influxdb3 import list`.

**User auth and RBAC (preview)**: Multi-user authentication with username/password → JWTs, optional OAuth/OIDC, and three built-in roles (Admin, Auditor, Member). Off by default (`--without-user-auth true`). 

**Object-store license portability**: Licenses are no longer bound to object-store config (type, bucket, endpoint, region) — validation enforces only signature, expiry, and licensed core count. You can move buckets or stores with the same license.

**Observability**: 36 new `influxdb3_compactor_*` Prometheus metrics, with `influxdb3_compactor_snapshot_lag_seconds` as the primary health signal.

##### Breaking Changes

- **Catalog v3 migration is one-way**: Back up your catalog before upgrading (see above).
- **`--pt-partition-count` renamed to `--pt-shard-count`**; there's no alias, so update startup scripts.
- **`/api/v2/write` returns `403`** (was `401`) for valid tokens lacking write permission; line-protocol parse errors now return `400` (was `500`).

###### Bug Fixes
- Compaction stability improvements (ingest-time, deadlock/write-amplification, gen1 orphaning, and upgrade-blocking fixes), plus several other bug fixes and performance improvements.

- Many other bug fixes and performance improvements

##### v2.8.0 [2025/12/12]
--------------------
###### Bug Fixes

1. [305e61d](https://github.com/influxdata/influxdb/commit/305e61d): Fix compilation on alpine linux

###### Features

1. [5e204dc](https://github.com/influxdata/influxdb/commit/5e204dc): Add optional token hashing

###### Token Hashing

InfluxDB OSS 2.8.0 introduces token hashing. When activated using the --use-hashed-tokens, all API tokens are stored as hashes on disk. While token hashing is a valuable security upgrade, care should be taken when upgrading and enabling token hashing. 

Documentation link: [use-hashed-tokens](https://docs.influxdata.com/influxdb/v2/reference/config-options/#use-hashed-tokens)

 It is *highly* recommended to upgrade to 2.8.0 or later versions and enable hashed tokens in two steps, not one.

###### How Token Hashing Works

Upon upgrading to version 2.8.0 or later releases from version 2.7.12 or earlier releases, the BoltDB schema is upgraded to add a new index bucket. 

Upon startup when token hashing is enabled, all unhashed tokens are converted to hashed tokens and unhashed tokens are deleted. This check and conversion of unhashed tokens occurs on every startup when token hashing is enabled. 

When token hashing is disabled, any new tokens are stored as hashed tokens. If token hashing is disabled after being disabled, newly created tokens are stored unhashed. However, existing tokens remain hashed on disk.

###### Hashed Tokens Are Lost During Downgrade

Be aware that once token hashing is enabled, downgrading to a version earlier than 2.8.0 will erase all API tokens due to the required schema downgrade. This means downgrading requires recreating all API tokens and updating them on clients. Even if token hashing is disabled before downgrading, all API tokens will still need to be recreated because disabling token hashing does not unhash tokens stored in hashed form.

If token hashing is *never* enabled, then it is possible to downgrade from 2.8.0 to 2.7.12 and earlier.

###### Recommended Process

It is not necessary to enabled token hashing immediately after upgrading. Token hashing is also not required by 2.8.0. 

1. Upgrade InfluxDB.
   1. Initiate influxd shutdown.
   2. Wait for a clean shutdown.
   3. Upgrade influxd.
   4. Start influxd.
2. Verify upgrade is successful.
3. Enable Token Hashing (if desired)
   1. Initiate influxd shutdown.
   2. Wait for a clean shutdown.
   3. Update configuration to use token hashing by adding --use-hashed-tokens to the command line or INFLUXD_USE_HASHED_TOKENS=true to the container environment. Or set use-hashed-tokens to true in the configuration file.
   4. Start influxd.
