| <br><h2>Signing Keys</h2> |
| <p>It is essential that you verify the integrity of the downloaded files using the PGP or MD5 signatures.</p> |
| |
| <p>The PGP signatures can be verified using PGP or GPG. First download the KEYS as well as the `ASC` signature file |
| for the relevant distribution. Make sure you get these files from the main distribution directory, rather than |
| from a mirror. Then verify the signatures using: |
| |
| <pre style="background-color: #C0C0C0; padding: 0px 20px 20px 20px;"><code> |
| % pgpk -a KEYS % pgpv apache-trafficcontrol-8.0.1.tar.gz.asc |
| </code> |
| or |
| <code> |
| % pgp -ka KEYS |
| % pgp apache-trafficcontrol-8.0.1.tar.gz.asc |
| </code> |
| or |
| <code> |
| % gpg --import KEYS |
| % gpg --verify apache-trafficcontrol-8.0.1.tar.gz.asc apache-trafficcontrol-8.0.1.tar.gz |
| </code> </pre> |
| |
| |
| <pre style="background-color: #C0C0C0; padding: 0px 20px 20px 20px;"><code> |
| $ gpg --verify apache-trafficcontrol-8.0.1.tar.gz.asc apache-trafficcontrol-8.0.1.tar.gz |
| gpg: Signature made Wed Mar 27 10:55:24 2024 MDT |
| gpg: using RSA key 383FAA8E2028BB4796DFE5A177B0253DC9954099 |
| gpg: Good signature from "Rima Shah <rshah@apache.org>" [ultimate] |
| </code></pre> |
| |
| </p> |
| |
| <p>Additionally, you should verify the SHA signature on the files. A unix program called `sha` or `shasum` is |
| included in many unix distributions. It is also available as part of GNU Textutils. An MD5 signature |
| (deprecated) consists of 32 hex characters, and a SHA512 signature consists of 128 hex characters. Ensure your |
| generated signature string matches the signature string published in the files above. |
| </p> |

| <h4>Release Notes</h4> |
| <h5><u>Traffic Ops</u></h5> |
| <p class="card-text"> |
| <ul> |
| <li><strong>Client Certificate Authentication</strong>: The ability for a Traffic Ops (TO) instance to accept TLS certificates from a client request and verify them against specified Root CA’s certificate as a form of login. This is not to be confused with mTLS, albeit a similar design. Should a client not send a TLS certificate as part of the request login functionality will default to standard form authentication.</li> |
| <li>Assignment of multiple Server Capabilities to a Server and vice-versa: Previous releases only allowed 1:1 assignment of server to a capability and vice-versa. This release now supports multiple assignments (1:many).</li> |
| <li>Simplification of CDN configs by removing hypnotoad section (used in deploying TO locally or in CIAB) was no longer being used.</li> |
| <li><strong>Layered Profile</strong>: Aggregation of parameters based on profile priority.</li> |
| <li><strong>Delivery Services</strong>: Regional field added to aid <code>maxOriginConnections</code></li> |
| <li><strong>Permission and Roles</strong>: Added new permissions (e.g.: <code>SSL-KEY_EXPIRATION:READ</code>, <code>ACME:READ</code>, etc.) to various roles. Also created a new role (<code>trouter</code>) to monitor Traffic Ops resources. Return empty array when no permission are given for a roles API (PUT, POST)</li> |
| <li><strong>Reporting</strong>: Added a feature to indicate success and failure during server upgrade.</li> |
| <li><strong>OAuth</strong> Added OAuth security when using Microsoft Authenticator and an optional field <code>oauth_user_attribute</code> for OAuth login credentials along with usage of ID token instead of Access Token for authentication.</li> |
| <li><a href="https://github.com/apache/trafficcontrol/issues/7674">#7674</a> Added the ability to indicate if a server failed its revalidate/config update.</li> |

| <li><a href="https://github.com/apache/trafficcontrol/issues/7519">#7519</a> Fixed TO API <code>/servers/{id}/deliveryservices</code> endpoint to responding with all DS’s on cache that are directly assigned and inherited through topology.</li> |

| </ul> |
| <h6>Breaking changes:</h6> |
| <ul> |
| <li>Fixed DS “ACTIVE” flag (<a href="https://github.com/apache/trafficcontrol/pull/4654">Blueprint</a>): Previously setting a Delivery Service (DS) to “Inactive” actually only sets it to “not routed”. There is no way to create a Delivery Service (with assigned servers) that will not be distributed to cache server configuration. This fix changes the <code>Active</code> property of Delivery Services from a boolean to an enumerated string constant that can represent three different “Activity States” for a Delivery Service.</li> |
| <li>Updated <code>LastUpdated</code> field across multiple APIs to use <code>RFC3339</code> instead of deprecated <code>time.Time</code>.</li> |
| <li>Capabilities are now part of DS structure instead of a separate struct.</li> |
| </ul> |
| </p> |
| |
| <h5><u>Traffic Portal</u></h5> |
| <p class="card-text"> |
| <p><strong>Delivery Service (DS)</strong>:</p> |
| <ul> |

| <li>Added the ability to tell if a DS has the target of another steering DS.</li> |
| <li>New config options in traffic_portal_properties.json for DS active flag feature.</li> |
| </ul> |
| <p><strong>Certs</strong>: Added visuals to DS cert expiration grid rows and the the ability to inspect a user provider cert, or the cert chain on DS SSL keys, and to delete a cert. Also added a revert certificate functionality.</p> |
| <p><strong>Servers</strong>: Improved information about profile priorities with respect to layered profile.</p> |
| <p><strong>Change Log</strong>: Ability to view entire log message by clicking on it.</p> |
| <p><strong>CDN</strong>: Added <code>TTLOverride</code> field to allow a quick turnaround time when performing TR maintenance that involves restarts.</p> |
| <p><strong>UI Beautification</strong>: Added better labels for widgets, simplifying DS button bar by moving DS changes/ DSRs under More menu, obscure sensitive text in <code>raw remap</code> fields, private SSL keys, “Header Rewrite” rules, and ILO interface passwords.</p> |
| <ul> |
