23.1.1

Features:

• Add error and sample rate fields to the replay event parser. (#1745)
• Add instruction_addr_adjustment field to RawStacktrace. (#1716)
• Add SSL support to relay-redis crate. It is possible to use rediss scheme to connnect to Redis cluster using TLS. (#1772)

Internal:

• Fix type errors in replay recording parsing. (#1765)

23.1.0

Features:

• Add support for limits.keepalive_timeout configuration. (#1645)
• Add support for decaying functions in dynamic sampling rules. (#1692)
• Stop extracting duration metric for session payloads. (#1739)

Internal:

• Remove concurrent profiling. (#1697)
• Use the main Sentry SDK to submit crash reports instead of a custom curl-based backend. This removes a dependency on libcurl and ensures compliance with latest TLS standards for crash uploads. Note that this only affects Relay if the hidden _crash_db option is used. (#1707)
• Support transaction naming rules. (#1695)
• Add PII scrubbing to URLs captured by replay recordings (#1730)
• Add more measurement units for profiling. (#1732)
• Add backoff mechanism for fetching projects from the project cache. (#1726)

22.12.0

Features:

• The level of events created from Unreal Crash Reports now depends on whether it was an actual crash or an assert. (#1677)
• Dynamic sampling is now based on the volume received by Relay by default and does not include the original volume dropped by client-side sampling in SDKs. This is required for the final dynamic sampling feature in the latest Sentry plans. (#1591)
• Add OpenTelemetry Context. (#1617)
• Add app.in_foreground and thread.main flag to protocol. (#1578)
• Add support for View Hierarchy attachment_type. (#1642)
• Add invalid replay recording outcome. (#1684)
• Stop rejecting spans without a timestamp, instead giving them their respective event timestamp and setting their status to DeadlineExceeded. (#1690)
• Add max replay size configuration parameter. (#1694)
• Add abnormal_mechanism field to SessionUpdate protocol. (#1665)

Bug Fixes:

• Make attachment_type on envelope items forward compatible by adding fallback variant. (#1638)
• Relay no longer accepts transaction events older than 5 days. Previously the event was accepted and stored, but since metrics for such old transactions are not supported it did not show up in parts of Sentry such as the Performance landing page. (#1663)
• Apply dynamic sampling to transactions from older SDKs and even in case Relay cannot load project information. This avoids accidentally storing 100% of transactions. (#1667)
• Replay recording parser now uses the entire body rather than a subset. (#1682)
• Fix a potential OOM in the Replay recording parser. (#1691)

Internal:

• Emit a service.back_pressure metric that measures internal back pressure by service. (#1583)
• Track metrics for OpenTelemetry events. (#1618)
• Normalize transaction name for URLs transaction source, by replacing UUIDs, SHAs and numerical IDs in transaction names by placeholders. (#1621)
• Parse string as number to handle a release bug. (#1637)
• Expand Profiling's discard reasons. (#1661, #1685)
• Allow to rate limit profiles on top of transactions. (#1681)

22.11.0

Features:

• Add PII scrubber for replay recordings. (#1545)
• Support decaying rules. Decaying rules are regular sampling rules, but they are only applicable in a specific time range. (#1544)
• Disallow - in measurement and breakdown names. These items are converted to metrics, which do not allow - in their name. (#1571)

Bug Fixes:

• Validate the distribution name in the event. (#1556)
• Use correct meta object for logentry in light normalization. (#1577)

Internal:

• Implement response context schema. (#1529)

• Report outcomes for dynamic sampling with the correct indexed transaction data category to restore correct totals. (#1561)
• Add fields to the Frame object for the sample format. (#1562)
• Move kafka related code into separate relay-kafka crate. (#1563)

22.10.0

Features:

• Limit the number of custom measurements per event. (#1483))
• Add INP web vital as a measurement. (#1487)

** Bug Fixes**:

• Support transaction_info on event payloads. (#1330)

Bug Fixes:

• Parse custom units with length < 15 without crashing. (#1312)
• Split large metrics requests into smaller batches. This avoids failed metrics submission and lost Release Health data due to 413 Payload Too Large errors on the upstream. (#1326)
• Metrics extraction: Map missing transaction status to "unknown". (#1333)
• Fix CVE-2022-2068 and CVE-2022-2097 by updating to OpenSSL 1.1.1q. (#1334)

• Extract metrics also from trace-sampled transactions. (#1317)
• Extract metrics from a configurable amount of custom transaction measurements. (#1324)
• Metrics: Drop transaction tag for high-cardinality sources. (#1339)

22.6.0

Compatibility: This version of Relay requires Sentry server 22.6.0 or newer.

Features:

• Relay is now compatible with CentOS 7 and Red Hat Enterprise Linux 7 onward (kernel version 2.6.32), depending on glibc 2.17 or newer. The crash-handler feature, which is currently enabled in the build published to DockerHub, additionally requires curl 7.29 or newer. (#1279)
• Optionally start relay with --upstream-dsn to pass a Sentry DSN instead of the URL. This can be convenient when starting Relay in environments close to an SDK, where a DSN is already available. (#1277)
• Add a new runtime mode --aws-runtime-api=$AWS_LAMBDA_RUNTIME_API that integrates Relay with the AWS Extensions API lifecycle. (#1277)
• Add ReplayRecording ItemType. (#1236)

Bug Fixes:

• Session metrics extraction: Count distinct_ids from all session updates to prevent undercounting users. (#1275)

• Session metrics extraction: Count crashed+abnormal towards errored_preaggr. (#1274)

Internal:

• Add version 3 to the project configs endpoint. This allows returning pending results which need to be polled later and avoids blocking batched requests on single slow entries. (#1263)
• Emit specific event type tags for "processing.event.produced" metric. (#1270)
• Add support for profile outcomes. (#1272)
• Avoid potential panics when scrubbing minidumps. (#1282)
• Fix typescript profile validation. (#1283)
• Track memory footprint of metrics buckets. (#1284, #1287, #1288)
• Support dedicated topics per metrics usecase, drop metrics from unknown usecases. (#1285)
• Add support for Rust profiles ingestion (#1296)

22.5.0

Features:

• Add platform, op, http.method and status tag to all extracted transaction metrics. (#1227)
• Add units in built-in measurements. (#1229)
• Add protocol support for custom units on transaction measurements. (#1256)

Bug Fixes:

• fix(metrics): Enforce metric name length limit. (#1238)
• Accept and forward unknown Envelope items. In processing mode, drop items individually rather than rejecting the entire request. This allows SDKs to send new data in combined Envelopes in the future. (#1246)
• Stop extracting metrics with outdated names from sessions. (#1251, #1252)
• Update symbolic to pull in fixed Unreal parser that now correctly handles zero-length files. (#1266)

Internal:

• Add sampling + tagging by event platform and transaction op. Some (unused) tagging rules from 22.4.0 have been renamed. (#1231)
