ManageEngine M365 Security Plus vs Rho: at a glance
What is ManageEngine M365 Security Plus?
An on-prem M365 auditing tool whose releases are mostly dependency hygiene.
M365 Security Plus is an on-premises Java application for auditing and alerting on Microsoft 365 activity, shipped as numbered builds a few times a year. The last two builds are typical of the pattern: 4821 upgrades the bundled JRE from Java 8 to 11 and refreshes 7-Zip and Jackson libraries, while 4820 carries the only real functional work in the window — mailbox backups to local, shared, or NAS repositories, PST splitting for large exports, bulk mailbox selection from CSV, and audit logs that show object names instead of GUIDs. Security fixes appear in nearly every build.
What is Rho?
Rho's release machinery finally produced a stable build — and it shipped no new product.
Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

ManageEngine M365 Security Plus
5.0ANALYTICS
An on-prem M365 auditing tool whose releases are mostly dependency hygiene.
◆ Current state
M365 Security Plus is an on-premises Java application for auditing and alerting on Microsoft 365 activity, shipped as numbered builds a few times a year. The last two builds are typical of the pattern: 4821 upgrades the bundled JRE from Java 8 to 11 and refreshes 7-Zip and Jackson libraries, while 4820 carries the only real functional work in the window — mailbox backups to local, shared, or NAS repositories, PST splitting for large exports, bulk mailbox selection from CSV, and audit logs that show object names instead of GUIDs. Security fixes appear in nearly every build.
◆ Where it's heading
Two forces set the release agenda, and neither is a roadmap. The first is Microsoft: deprecated cmdlets forced an audit rewrite onto Get-MessageTraceV2, and a tenant configuration change broke onboarding until build 4817 patched around it. The second is the supply chain — Log4j, Tomcat, Bouncy Castle, Zulu JRE, and now the Java 8 to 11 jump, all tracked build by build because on-premises customers inherit whatever the vendor bundles. The product work that does land clusters around the Backup module, which is the one area growing rather than being maintained.
◆ Prediction
With the JRE finally past Java 8, Tomcat 9 is the next end-of-life dependency in the bundle, and the Backup module's steady additions suggest export and retention options continue there.
Rho
6.3ANALYTICS
Rho's release machinery finally produced a stable build — and it shipped no new product.
◆ Current state
Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.
◆ Where it's heading
The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, checksums bound to exact commits, and limitations named out loud rather than buried. That discipline has now paid off in the only way it could — 0.4.0 stable ships a Windows installer, a notarized macOS disk image and a Linux AppImage that can all update themselves, with failed verification preserving the running version. The feed's long-standing pattern of dev.NN builds with no final has broken; feature work and shipping work were on separate tracks, and the shipping track arrived first.
◆ Prediction
With distribution solved, the next entry that matters is the first one describing product capability again rather than packaging. The unresolved item these releases name themselves is Windows trust: the installer is still signed with a SignPath Free Trial self-signed certificate that SmartScreen may warn on.
