"previous: Upgrading to 2.7.1":#v2_7_1
+h3. Debian 10, Ubuntu 18.04, and CentOS 7 are no longer supported
+
+Arvados 3.0 no longer supports some of the older distributions supported by Arvados 2.7: Debian 10 "buster," Ubuntu 18.04 "bionic," and CentOS 7. If you are running Arvados on any of these distributions, you must first upgrade to the next major release of your distribution before you upgrade to Arvados 3.0.
+
+Arvados 2.7 supports Debian 11 "bullseye," Ubuntu 20.04 "focal," and CentOS 8. You can upgrade to one of those releases, then proceed to upgrade Arvados to 3.0.
+
+h3. RVM is no longer supported
+
+Some Arvados packages, most notably the Rails API server package @arvados-api-server@, would check whether RVM is installed on the system, and invoke Ruby commands through it if so. Arvados 3.0 no longer specially supports RVM. Instead, Arvados 3.0 supports all the different versions of Ruby that are packaged in our supported distributions, mitigating the need to support separate Ruby installations. Package scripts run plain @ruby@ and @gem@ commands and expect they come from a supported version.
+
+If you have a custom install that requires a different version of Ruby than the one included with your distribution, you must configure your system to ensure package scripts find that version of @ruby@ before any others. For example, you might do this on Debian-based distributions by customizing apt's @DPkg::Path@ setting.
+
+h3. S3 volume IAMRole configuration entry has been removed
+
+The @Volumes.*.DriverParameters.IAMRole@ configuration entry for S3 volumes has been removed. You should remove it from your @/etc/arvados/config.yml@ file to avoid warnings when services start up. As before, if @AccessKeyID@ and @SecretAccessKey@ are blank, keepstore will retrieve IAM role credentials from instance metadata. Previously, documentation indicated that keepstore would refuse to use the IAM credentials if @IAMRole@ was specified and did not match the instance metadata, but that check has not been working for some time.
+
+h3. Legacy container logging system has been removed
+
+The following configuration keys are no longer supported. Remove them from your @/etc/arvados/config.yml@ file to avoid warnings when services start up.
+* @Containers.Logging.LimitLogBytesPerJob@
+* @Containers.Logging.LogBytesPerEvent@
+* @Containers.Logging.LogPartialLineThrottlePeriod@
+* @Containers.Logging.LogSecondsBetweenEvents@
+* @Containers.Logging.LogThrottleBytes@
+* @Containers.Logging.LogThrottleLines@
+* @Containers.Logging.LogThrottlePeriod@
+* @Containers.Logging.MaxAge@
+* @Containers.Logging.SweepInterval@
+
+Any container logging content remaining in the database from the legacy system will be deleted.
+
+h3. Virtual environments inside distribution Python packages have moved
+
+The distribution packages that we publish for Python packages include an entire virtualenv with all required libraries. In Arvados 3.0 these virtualenvs have moved from @/usr/share/python3/dist/PACKAGE_NAME@ to @/usr/lib/PACKAGE_NAME@ to prevent conflicts with distribution packages and better conform to filesystem standards.
+
+If you only run the executables installed by these packages, you don't need to change anything. Those are still installed under @/usr/bin@ and will use the new location when you upgrade. If you have written your own scripts or tools that rely on these virtualenvs, you may need to update those with the new location. For example, if you have a shell script that activates the virtualenv by running:
+
+<pre><code class="shell">source /usr/share/python3/dist/python3-arvados-python-client/bin/activate</code></pre>
+
+You must update it to:
+
+<notextile>
+<pre><code class="shell">source <span class="userinput">/usr/lib/python3-arvados-python-client</span>/bin/activate</code></pre>
+</notextile>
+
+If you have a Python script with this shebang line:
+
+<pre><code class="shell">#!/usr/share/python3/dist/python3-arvados-python-client/bin/python</code></pre>
+
+You must update it to:
+
+<notextile>
+<pre><code class="shell">#!<span class="userinput">/usr/lib/python3-arvados-python-client</span>/bin/python</code></pre>
+</notextile>
+
h3. WebDAV service uses @/var/cache@ for file content
@keep-web@ now stores copies of recently accessed data blocks in @/var/cache/arvados/keep@ instead of in memory. That directory will be created automatically. The default cache size is 10% of the filesystem size. Use the new @Collections.WebDAVCache.DiskCacheSize@ config to specify a different percentage or an absolute size.
If the previously supported @MaxBlockEntries@ config is present, remove it to avoid warning messages at startup.
+h3. Check MaxGatewayTunnels config
+
+If you use the LSF or Slurm dispatcher, ensure the new @API.MaxGatewayTunnels@ config entry is high enough to support the size of your cluster. See "LSF docs":{{site.baseurl}}/install/crunch2-lsf/install-dispatch.html#MaxGatewayTunnels or "Slurm docs":{{site.baseurl}}/install/crunch2-slurm/install-dispatch.html#MaxGatewayTunnels for details.

h2(#2_7_1). v2.7.1 (2023-12-12)
"previous: Upgrading to 2.7.0":#v2_7_0
h3. Deprecated/legacy APIs slated for removal
-The legacy APIs "humans":../api/methods/humans.html, "specimens":../api/methods/specimens.html, "traits":../api/methods/traits.html, "jobs":../api/methods/jobs.html, "job_tasks":../api/methods/job_tasks.html, "pipeline_instances":../api/methods/pipeline_instances.html, "pipeline_templates":../api/methods/pipeline_templates.html, "nodes":../api/methods/nodes.html, "repositories":../api/methods/repositories.html, and "keep_disks":../api/methods/keep_disks.html are deprecated and will be removed in a future major version of Arvados.
+The legacy APIs "humans":https://doc.arvados.org/v2.7/api/methods/humans.html, "specimens":https://doc.arvados.org/v2.7/api/methods/specimens.html, "traits":https://doc.arvados.org/v2.7/api/methods/traits.html, "jobs":https://doc.arvados.org/v2.7/api/methods/jobs.html, "job_tasks":https://doc.arvados.org/v2.7/api/methods/job_tasks.html, "pipeline_instances":https://doc.arvados.org/v2.7/api/methods/pipeline_instances.html, "pipeline_templates":https://doc.arvados.org/v2.7/api/methods/pipeline_templates.html, "nodes":https://doc.arvados.org/v2.7/api/methods/nodes.html, "repositories":https://doc.arvados.org/v2.7/api/methods/repositories.html, and "keep_disks":https://doc.arvados.org/v2.7/api/methods/keep_disks.html are deprecated and will be removed in a future major version of Arvados.
In addition, the @default_owner_uuid@, @api_client_id@, and @user_id@ fields of "api_client_authorizations":../api/methods/api_client_authorizations.html are deprecated and will be removed from @api_client_authorization@ responses in a future major version of Arvados. This should not affect clients as @default_owner_uuid@ was never implemented, and @api_client_id@ and @user_id@ returned internal ids that were not meaningful or usable with any other API call.
