7.0.0 - 2022-07-19

Added

[Traffic Portal] Added Layered Profile feature to /servers/
#6448 Added status and lastPoll fields to the publish/CrStates endpoint of Traffic Monitor (TM).
Added back to the health-client the status field logging with the addition of the filed to publish/CrStates
Added a new Traffic Ops endpoint to GET capacity and telemetry data for CDNi integration.
Added SOA (Service Oriented Architecture) capability to CDN-In-A-Box.
Added a Traffic Ops endpoints to PUT a requested configuration change for a full configuration or per host and an endpoint to approve or deny the request.
Traffic Monitor config option distributed_polling which enables the ability for Traffic Monitor to poll a subset of the CDN and divide into "local peer groups" and "distributed peer groups". Traffic Monitors in the same group are local peers, while Traffic Monitors in other groups are distributed peers. Each TM group polls the same set of cachegroups and gets availability data for the other cachegroups from other TM groups. This allows each TM to be responsible for polling a subset of the CDN while still having a full view of CDN availability. In order to use this, stat_polling must be disabled.
Added support for a new Traffic Ops GLOBAL profile parameter -- tm_query_status_override -- to override which status of Traffic Monitors to query (default: ONLINE).
Traffic Ops: added new cdn.conf option -- user_cache_refresh_interval_sec -- which enables an in-memory users cache to improve performance. Default: 0 (disabled).
Traffic Ops: added new cdn.conf option -- server_update_status_cache_refresh_interval_sec -- which enables an in-memory server update status cache to improve performance. Default: 0 (disabled).
Traffic Router: Add support for file-protocol URLs for the geolocation.polling.url for the Geolocation database.

[Traffic Portal] Added the ability for users to view Delivery Service Requests corresponding to individual Delivery Services in TP.
[Traffic Ops] Added support for backend configurations so that Traffic Ops can act as a reverse proxy for these services #6754.
Added functionality for CDN locks, so that they can be shared amongst a list of specified usernames.

Added layered profile feature to 4.0 for GET /deliveryservices/{id}/servers/ and /deliveryservices/{id}/servers/eligible.
Change to t3c regex_revalidate so that STALE is no longer explicitly added for default revalidate rule for ATS version backwards compatibility.
Change to t3c diff to flag a config file for replacement if owner/group settings are not ats #6879.
t3c now looks in the executable dir path for t3c- utilities
Added support for parent.config markdown/retry DS parameters using first./inner./last. prefixes. mso. and prefixes should be deprecated.
Add new REGEX_REMAP_DIRECTIVE support to raw remap text to allow moving the regex_remap placement.
t3c change t3c diff call to t3c-diff to fix a performance regression.
Added a sub-app t3c-tail to tail diags.log and capture output when t3c reloads and restarts trafficserver

Go version 1.17 is used to compile Traffic Ops, T3C, Traffic Monitor, Traffic Stats, and Grove.

Deprecated

The Riak Traffic Vault backend is now deprecated and its support may be removed in a future release. It is highly recommended to use the new PostgreSQL backend instead.
The riak.conf config file and its corresponding --riakcfg option in traffic_ops_golang have been deprecated. Please use "traffic_vault_backend": "riak" and "traffic_vault_config" (with the existing contents of riak.conf) instead.
The Traffic Ops API route GET /api/{version}/vault/bucket/{bucket}/key/{key}/values has been deprecated and will no longer be available as of Traffic Ops API v4
The Traffic Ops API route POST /api/{version}/deliveryservices/request has been deprecated and will no longer be available as of Traffic Ops API v4
The Traffic Ops API routes GET /api/{version}/cachegroupparameters, POST /api/{version}/cachegroupparameters, GET /api/{version}/cachegroups/{id}/parameters, and DELETE /api/{version}/cachegroupparameters/{cachegroupID}/{parameterId} have been deprecated and will no longer be available as of Traffic Ops API v4
The riak_port option in cdn.conf is now deprecated. Please use the "port" field in traffic_vault_config instead.
The traffic_ops_ort.pl tool has been deprecated in favor of t3c, and will be removed in the next major version.
With the release of ATC v6.0, major API version 2 is now deprecated, subject to removal with the next ATC major version release, at the earliest.

Removed

Removed the unused backend_max_connections option from cdn.conf.
Removed the unused http_poll_no_sleep, max_stat_history, max_health_history, cache_health_polling_interval_ms, cache_stat_polling_interval_ms, and peer_polling_interval_ms Traffic Monitor config options.
Removed the Long Description 2 and Long Description 3 fields of DeliveryService from the UI, and changed the backend so that routes corresponding API 4.0 and above no longer accept or return these fields.
The Perl implementation of Traffic Ops has been stripped out, along with the Go implementation's "fall-back to Perl" behavior.
Traffic Ops no longer includes an app/public directory, as the static webserver has been removed along with the Perl Traffic Ops implementation. Traffic Ops also no longer attempts to download MaxMind GeoIP City databases when running the Traffic Ops Postinstall script.
The compare tool stack has been removed, as it no longer serves a purpose.
Removed the Perl-only cdn.conf option geniso.iso_root_path
t3c dispersion flags. These flags existed in ort.pl and t3c, but the feature has been removed in t3c-apply. The t3c run is fast enough now, there's no value or need in internal logic, operators can easily use shell pipelines to randomly sleep before running if necessary.

Changed

Changed some Traffic Ops Go Client methods to use DeliveryServiceNullable inputs and outputs.
When creating invalidation jobs through TO/TP, if an identical regex is detected that overlaps its time, then warnings will be returned indicating that overlap exists.
Changed Traffic Portal to disable browser caching on GETs until it utilizes the If-Modified-Since functionality that the TO API now provides.
Changed Traffic Portal to use Traffic Ops API v3
Changed Traffic Portal to use the more performant and powerful ag-grid for all server and invalidation request tables.
Changed ORT Config Generation to be deterministic, which will prevent spurious diffs when nothing actually changed.
Changed ORT to find the local ATS config directory and use it when location Parameters don't exist for many required configs, including all Delivery Service files (Header Rewrites, Regex Remap, URL Sig, URI Signing).
Changed ORT to not update ip_allow.config but log an error if it needs updating in syncds mode, and only actually update in badass mode.
- ATS has a known bug, where reloading when ip_allow.config has changed blocks arbitrary addresses. This will break things by not allowing any new necessary servers, but prevents breaking the Mid server. There is no solution that doesn't break something, until ATS fixes the bug, and breaking an Edge is better than breaking a Mid.
Changed the access logs in Traffic Ops to now show the route ID with every API endpoint call. The Route ID is appended to the end of the access log line.
Changed Traffic Monitor's tmconfig.backup to store the result of GET /api/2.0/cdns/{{name}}/configs/monitoring instead of a transformed map
Changed OAuth workflow to use Basic Auth if client secret is provided per RFC6749 section 2.3.1.
Multiple Interface Servers
- Interface data is constructed from IP Address/Gateway/Netmask (and their IPv6 counterparts) and Interface Name and Interface MTU fields on services. These MUST have proper, valid data before attempting to upgrade or the upgrade WILL fail. In particular IP fields need to be valid IP addresses/netmasks, and MTU must only be positive integers of at least 1280.
- The /servers and /servers/{{ID}}} TO API endpoints have been updated to use and reflect multi-interface servers.
- Updated /cdns/{{name}}/configs/monitoring TO API endpoint to return multi-interface data.
- CDN Snapshots now use a server's "service addresses" to provide its IP addresses.
- Changed the Cache States tab of the Traffic Monitor UI to properly handle multiple interfaces.
- Changed the /publish/CacheStats in Traffic Monitor to support multiple interfaces.
- Changed the CDN-in-a-Box server enrollment template to support multiple interfaces.
Changed Tomcat Java dependency to 8.5.57.
Changed Spring Framework Java dependency to 4.2.5.
Changed certificate loading code in Traffic Router to use Bouncy Castle instead of deprecated Sun libraries.
Changed deprecated AsyncHttpClient Java dependency to use new active mirror and updated to version 2.12.1.
Changed Traffic Portal to use the more performant and powerful ag-grid for the delivery service request (DSR) table.
Traffic Ops: removed change log entry created during server update/revalidation unqueue
Updated CDN in a Box to CentOS 8 and added RHEL_VERSION Docker build arg so CDN in a Box can be built for CentOS 7, if desired
Added Delivery Service Raw Remap __CACHEKEY_DIRECTIVE__ directive to allow inserting the cachekey directive into the Raw Remap text. This allows Raw Remaps which manipulate the cachekey.

Deprecated

Deprecated the non-nullable DeliveryService Go struct and other structs that use it. DeliveryServiceNullable structs should be used instead.
Deprecated the insecure option in traffic_ops_golang in favor of "tls_config": { "InsecureSkipVerify": <bool> }
Importing Traffic Ops Go clients via the un-versioned github.com/apache/trafficcontrol/traffic_ops/client is now deprecated in favor of versioned import paths e.g. github.com/apache/trafficcontrol/traffic_ops/v3-client.

Removed

Removed deprecated Traffic Ops Go Client methods.
Configuration generation logic in the TO API (v1) for all files and the "meta" route - this means that versions of Traffic Ops ORT earlier than 4.0.0 will not work any longer with versions of Traffic Ops moving forward.
Removed from Traffic Portal the ability to view cache server config files as the contents are no longer reliable through the TO API due to the introduction of atstccfg.

4.1.0 - 2020-04-23

Added

Added support for use of ATS Slice plugin as an additonal option to range request handling on HTTP/DNS DSes.
Added a boolean to delivery service in Traffic Portal and Traffic Ops to enable EDNS0 client subnet at the delivery service level and include it in the cr-config.
Updated Traffic Router to read new EDSN0 client subnet field and route accordingly only for enabled delivery services. When enabled and a subnet is present in the request, the subnet appears in the chi field and the resolver address is in the rhi field.
Traffic Router DNSSEC zone diffing: if enabled via the new "dnssec.zone.diffing.enabled" TR profile parameter, TR will diff existing zones against newly generated zones in order to determine if a zone needs to be re-signed. Zones are typically generated on every snapshot and whenever new DNSSEC keys are found, and since signing a zone is a relatively CPU-intensive operation, this optimization can drastically reduce the CPU time taken to process new snapshots and new DNSSEC keys.
Added an optimistic quorum feature to Traffic Monitor to prevent false negative states from propagating to downstream components in the event of network isolation.
Added the ability to fetch users by role
Added an API 1.5 endpoint to generate delivery service certificates using Let's Encrypt
Added an API 1.5 endpoint to GET a single or all records for Let's Encrypt DNS challenge
Added an API 1.5 endpoint to renew certificates
Added ability to create multiple objects from generic API Create with a single POST.
Added debugging functionality to CDN-in-a-Box.
Added an SMTP server to CDN-in-a-Box.
Cached builder Docker images on Docker Hub to speed up build time
Added functionality in the GET endpoints to support the "If-Modified-Since" header in the incoming requests.

Modified Traffic Portal and Traffic Ops to accept IPv6 only servers.
Updated Traffic Monitor to default to polling both IPv4 and IPv6.
Traffic Ops, Traffic Monitor, Traffic Stats, and Grove are now compiled using Go version 1.14. This requires a Traffic Vault config update (see note below).
Existing installations must enable TLSv1.1 for Traffic Vault in order for Traffic Ops to reach it. See Enabling TLS 1.1 in the Traffic Vault administrator's guide for instructions.
Changed the totalBytes property of responses to GET requests to /deliveryservice_stats to the more appropriate totalKiloBytes in API 2.x
Fix to traffic_ops_ort to generate logging.yaml files correctly.
Fixed issue #4650: add the "Vary: Accept-Encoding" header to all responses from Traffic Ops

4.0.0 - 2019-12-16

Added

Traffic Router: TR now generates a self-signed certificate at startup and uses it as the default TLS cert. The default certificate is used whenever a client attempts an SSL handshake for an SNI host which does not match any of the other certificates.
Client Steering Forced Diversity: force Traffic Router to return more unique edge caches in CLIENT_STEERING results instead of the default behavior which can sometimes return a result of multiple targets using the same edge cache. In the case of edge cache failures, this feature will give clients a chance to retry a different edge cache. This can be enabled with the new "client.steering.forced.diversity" Traffic Router profile parameter.

Traffic Router: Added a tunable bounded queue to support DNS request processing.
Traffic Ops API Routing Blacklist: via the routing_blacklist field in cdn.conf, enable certain whitelisted Go routes to be handled by Perl instead (via the perl_routes list) in case a regression is found in the Go handler, and explicitly disable any routes via the disabled_routes list. Requests to disabled routes are immediately given a 503 response. Both fields are lists of Route IDs, and route information (ID, version, method, path, and whether or not it can bypass to Perl) can be found by running ./traffic_ops_golang --api-routes. To disable a route or have it bypassed to Perl, find its Route ID using the previous command and put it in the disabled_routes or perl_routes list, respectively.
To support reusing a single riak cluster connection, an optional parameter is added to riak.conf: "HealthCheckInterval". This options takes a 'Duration' value (ie: 10s, 5m) which affects how often the riak cluster is health checked. Default is currently set to: "HealthCheckInterval": "5s".
Added a new Go db/admin binary to replace the Perl db/admin.pl script which is now deprecated and will be removed in a future release. The new db/admin binary is essentially a drop-in replacement for db/admin.pl since it supports all of the same commands and options; therefore, it should be used in place of db/admin.pl for all the same tasks.
Added an API 1.4 endpoint, /api/1.4/cdns/dnsseckeys/refresh, to perform necessary behavior previously served outside the API under /internal.
Added the DS Record text to the cdn dnsseckeys endpoint in 1.4.
Added monitoring.json snapshotting. This stores the monitoring json in the same table as the crconfig snapshot. Snapshotting is now required in order to push out monitoring changes.
To traffic_ops_ort.pl added the ability to handle ##OVERRIDE## delivery service ANY_MAP raw remap text to replace and comment out a base delivery service remap rules. THIS IS A TEMPORARY HACK until versioned delivery services are implemented.
Snapshotting the CRConfig now deletes HTTPS certificates in Riak for delivery services which have been deleted in Traffic Ops.
Added a context menu in place of the "Actions" column from the following tables in Traffic Portal: cache group tables, CDN tables, delivery service tables, parameter tables, profile tables, server tables.
Traffic Portal standalone Dockerfile
In Traffic Portal, removes the need to specify line breaks using __RETURN__ in delivery service edge/mid header rewrite rules, regex remap expressions, raw remap text and traffic router additional request/response headers.
In Traffic Portal, provides the ability to clone delivery service assignments from one cache to another cache of the same type. Issue #2963.
Added an API 1.4 endpoint, /api/1.4/server_capabilities, to create, read, and delete server capabilities.
Traffic Ops now allows each delivery service to have a set of query parameter keys to be retained for consistent hash generation by Traffic Router.
In Traffic Portal, delivery service table columns can now be rearranged and their visibility toggled on/off as desired by the user. Hidden table columns are excluded from the table search. These settings are persisted in the browser.
Added an API 1.4 endpoint, /api/1.4/user/login/oauth to handle SSO login using OAuth.
Added /#!/sso page to Traffic Portal to catch redirects back from OAuth provider and POST token into the API.
In Traffic Portal, server table columns can now be rearranged and their visibility toggled on/off as desired by the user. Hidden table columns are excluded from the table search. These settings are persisted in the browser.
Added pagination support to some Traffic Ops endpoints via three new query parameters, limit and offset/page
Traffic Ops now supports a "sortOrder" query parameter on some endpoints to return API responses in descending order
Traffic Ops now uses a consistent format for audit logs across all Go endpoints
Added cache-side config generator, atstccfg, installed with ORT. Includes all configs. Includes a plugin system.
Fixed ATS config generation to omit regex remap, header rewrite, URL Sig, and URI Signing files for delivery services not assigned to that server.
In Traffic Portal, all tables now include a 'CSV' link to enable the export of table data in CSV format.
Pylint configuration now enforced (present in a file in the Python client directory)
Added an optional SMTP server configuration to the TO configuration file, api now has unused abilitiy to send emails
Traffic Monitor now has "gbps" calculated stat, allowing operators to monitor bandwidth in Gbps.
Added an API 1.4 endpoint, /api/1.4/deliveryservices_required_capabilities, to create, read, and delete associations between a delivery service and a required capability.
Added ATS config generation omitting parents without Delivery Service Required Capabilities.
In Traffic Portal, added the ability to create, view and delete server capabilities and associate those server capabilities with servers and delivery services. See blueprint
Added validation to prevent assigning servers to delivery services without required capabilities.
Added deep coverage zone routing percentage to the Traffic Portal dashboard.
Added a traffic_ops/app/bin/osversions-convert.pl script to convert the osversions.cfg file from Perl to JSON as part of the /osversions endpoint rewrite.
Added [Experimental] - Emulated Vault suppling a HTTP server mimicking RIAK behavior for usage as traffic-control vault.
Added Traffic Ops Client function that returns a Delivery Service Nullable Response when requesting for a Delivery Service by XMLID

Changed

Traffic Router: TR will now allow steering DSs and steering target DSs to have RGB enabled. (fixes #3910)
Traffic Portal: Traffic Portal now allows Regional Geo Blocking to be enabled for a Steering Delivery Service.
Traffic Ops: fixed a regression where the Expires cookie header was not being set properly in responses. Also, added the Max-Age cookie header in responses.
Traffic Router, added TLS certificate validation on certificates imported from Traffic Ops
- validates modulus of private and public keys
- validates current timestamp falls within the certificate date bracket
- validates certificate subjects against the DS URL
Traffic Ops Golang Endpoints
- Updated /api/1.1/cachegroups: Cache Group Fallbacks are included
- Updated /api/1.1/cachegroups: fixed so fallbackToClosest can be set through API
  - Warning: a PUT of an old Cache Group JSON without the fallbackToClosest field will result in a null value for that field
Traffic Router: fixed a bug which would cause REFUSED DNS answers if the zone priming execution did not complete within the configured zonemanager.init.timeout period.
Issue 2821: Fixed "Traffic Router may choose wrong certificate when SNI names overlap"
traffic_ops/app/bin/checks/ToDnssecRefresh.pl now requires "user" and "pass" parameters of an operations-level user! Update your scripts accordingly! This was necessary to move to an API endpoint with proper authentication, which may be safely exposed.
Traffic Monitor UI updated to support HTTP or HTTPS traffic.
Traffic Monitor health/stat time now includes full body download (like prior TM <=2.1 version)
Modified Traffic Router logging format to include an additional field for DNS log entries, namely rhi. This defaults to '-' and is only used when EDNS0 client subnet extensions are enabled and a client subnet is present in the request. When enabled and a subnet is present, the subnet appears in the chi field and the resolver address is in the rhi field.
Changed traffic_ops_ort.pl so that hdr_rw-<ds>.config files are compared with strict ordering and line duplication when detecting configuration changes.
Traffic Ops (golang), Traffic Monitor, Traffic Stats are now compiled using Go version 1.11. Grove was already being compiled with this version which improves performance for TLS when RSA certificates are used.
Fixed issue #3497: TO API clients that don't specify the latest minor version will overwrite/default any fields introduced in later versions
Fixed permissions on DELETE /api/$version/deliveryservice_server/{dsid}/{serverid} endpoint
Issue 3476: Traffic Router returns partial result for CLIENT_STEERING Delivery Services when Regional Geoblocking or Anonymous Blocking is enabled.
Upgraded Traffic Portal to AngularJS 1.7.8
Issue 3275: Improved the snapshot diff performance and experience.
Issue 3550: Fixed TC golang client setting for cache control max age
Issue #3605: Fixed Traffic Monitor custom ports in health polling URL.
Issue 3587: Fixed Traffic Ops Golang reverse proxy and Riak logs to be consistent with the format of other error logs.
Database migrations have been collapsed. Rollbacks to migrations that previously existed are no longer possible.
Issue #3750: Fixed Grove access log fractional seconds.
Issue #3646: Fixed Traffic Monitor Thresholds.
Modified Traffic Router API to be available via HTTPS.
Added fields to traffic_portal_properties.json to configure SSO through OAuth.
Added field to cdn.conf to configure whitelisted URLs for Json Key Set URL returned from OAuth provider.
Improved profile comparison view in Traffic Portal.
Issue #3871 - provides users with a specified role the ability to mark any delivery service request as complete.
Fixed Traffic Ops Golang POST servers/id/deliveryservice continuing erroneously after a database error.
Fixed Traffic Ops Golang POST servers/id/deliveryservice double-logging errors.
Issue #4131 - The "Clone Delivery Service Assignments" menu item is hidden on a cache when the cache has zero delivery service assignments to clone.
Traffic Portal - Turn off TLSv1
Removed Traffic Portal dependency on Restangular

3.0.0 - 2018-10-30

Added

Removed MySQL-to-Postgres migration tools. This tool is supported for 1.x to 2.x upgrades only and should not be used with 3.x.
Backup Edge Cache group: If the matched group in the CZF is not available, this list of backup edge cache group configured via Traffic Ops API can be used as backup. In the event of all backup edge cache groups not available, GEO location can be optionally used as further backup. APIs detailed here

Delivery Service Origins Refactor: The Delivery Service API now creates/updates an Origin entity on Delivery Service creates/updates, and the org_server_fqdn column in the deliveryservice table has been removed. The org_server_fqdn data is now computed from the Delivery Service's primary origin (note: the name of the primary origin is the xml_id of its delivery service).
Cachegroup-Coordinate Refactor: The Cachegroup API now creates/updates a Coordinate entity on Cachegroup creates/updates, and the latitude and longitude columns in the cachegroup table have been replaced with coordinate (a foreign key to Coordinate). Coordinates created from Cachegroups are given the name from_cachegroup_\<cachegroup name\>.
Geolocation-based Client Steering: two new steering target types are available to use for CLIENT_STEERING delivery services: STEERING_GEO_ORDER and STEERING_GEO_WEIGHT. When targets of these types have an Origin with a Coordinate, Traffic Router will order and prioritize them based upon the shortest total distance from client -> edge -> origin. Co-located targets are grouped together and can be weighted or ordered within the same location using STEERING_GEO_WEIGHT or STEERING_GEO_ORDER, respectively.
Tenancy is now the default behavior in Traffic Ops. All database entries that reference a tenant now have a default of the root tenant. This eliminates the need for the use_tenancy global parameter and will allow for code to be simplified as a result. If all user and delivery services reference the root tenant, then there will be no difference from having use_tenancy set to 0.
Cachegroup Localization Methods: The Cachegroup API now supports an optional localizationMethods field which specifies the localization methods allowed for that cachegroup (currently 'DEEP_CZ', 'CZ', and 'GEO'). By default if this field is null/empty, all localization methods are enabled. After Traffic Router has localized a client, it will only route that client to cachegroups that have enabled the localization method used. For example, this can be used to prevent GEO-localized traffic (i.e. most likely from off-net/internet clients) to cachegroups that aren't optimal for internet traffic.
Traffic Monitor Client Update: Traffic Monitor is updated to use the Traffic Ops v13 client.
Removed previously deprecated traffic_monitor_java
Added infrastructure/cdn-in-a-box for Apachecon 2018 demonstration
The CacheURL Delivery service field is deprecated. If you still need this functionality, you can create the configuration explicitly via the raw remap field.

2.2.0 - 2018-06-07

Added

Per-DeliveryService Routing Names: you can now choose a Delivery Service's Routing Name (rather than a hardcoded "tr" or "edge" name). This might require a few pre-upgrade steps detailed here
Delivery Service Requests: When enabled, delivery service requests are created when ALL users attempt to create, update or delete a delivery service. This allows users with higher level permissions to review delivery service changes for completeness and accuracy before deploying the changes.

Fair Queuing Pacing: Using the FQ Pacing Rate parameter in Delivery Services allows operators to limit the rate of individual sessions to the edge cache. This feature requires a Trafficserver RPM containing the fq_pacing experimental plugin AND setting 'fq' as the default Linux qdisc in sysctl.
Traffic Ops rpm changed to remove world-read permission from configuration files.
