• The surrounding quotes make this a string literal rather than an executable mongosh command, so users cannot use the snippet to verify the FCV.

'db.adminCommand({ getParameter: 1, featureCompatibilityVersion: 1 })'

docs/release_notes/8.3.8-2.md:65

• “Support” is a common noun here and should not be capitalized mid-sentence.

• The outer quotes turn this into a JavaScript string literal, so copying it into mongosh only echoes the text and does not set the FCV. The actual upgrade instructions use an executable db.adminCommand(...) call at docs/install/upgrade-from-80.md:104.

'db.adminCommand({ setFeatureCompatibilityVersion: "8.0", confirm: true })'

docs/release_notes/8.3.8-2.md:33

• The outer quotes make this a string literal rather than an executable command, so readers cannot use the sample to retrieve featureCompatibilityVersion. Remove them so mongosh invokes db.adminCommand.

'db.adminCommand({ getParameter: 1, featureCompatibilityVersion: 1 })'

docs/release_notes/8.3.8-2.md:21

• This fragment omits the periods from 8.3.8, unlike the adjacent release's upstream link (docs/release_notes/8.3.7-1.md:21), so it does not target the 8.3.8 section. Use the full version in the fragment.

This release of Percona Server for MongoDB includes the improvements and bug fixes of [MongoDB 8.3.8 Community Edition :octicons-link-external-16:](https://www.mongodb.com/docs/manual/release-notes/8.3#838---aug-11-2026){:target="_blank"}.

docs/release_notes/8.3.8-2.md:119

• The link label names MongoDB 8.3.2 even though this page incorporates 8.3.8, and the fragment also omits the periods used by the preceding 8.3.7 changelog link. Correct both so readers reach the matching upstream changelog section.

For the complete upstream changelog, see [MongoDB 8.3.2 Community Edition :octicons-link-external-16:](https://www.mongodb.com/docs/manual/release-notes/8.3-changelog/#838-changelog){:target="_blank"}.

variables.yml:14

• This changes the already-published 8.3.7-1 date from July 30 to July 22, which is the upstream MongoDB 8.3.7 date referenced in docs/release_notes/8.3.7-1.md:21. Because both the existing release page and index render this variable, the change incorrectly rewrites the Percona release date while adding 8.3.8-2 notes.

  8_3_7: "2026-07-22"

docs/release_notes/8.3.8-2.md:99

• CVE-2026-18704 is already assigned to SERVER-129936 on line 97, while this entry describes an unrelated $graphLookup memory-lifetime flaw. One of these CVE mappings is therefore incorrect; verify SERVER-128551 against the upstream advisory and replace this ID and URL.

- [SERVER-128551 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-128551){:target="_blank"} ([CVE-2026-18704 :octicons-link-external-16:](https://www.cve.org/CVERecord?id=CVE-2026-18704){:target="_blank"}): Fixed a memory handling error in the `$graphLookup` aggregation stage where an authenticated user could leave the server holding a reference to memory that had already been released. Later operations could crash the server process or, in some cases, run unintended code. Triggering this required the ability to run both aggregation and memory-management commands.

the date for 8.3.7 is incorrect, should be 2026-07-30
