What is Bandwidth?

Bandwidth sells trust in the call, and self-service everywhere it used to sell tickets.

The release stream splits cleanly in two: one entry that adds a product line and a run of entries that remove reasons to open a support ticket. Identity Presentation, in beta since mid-August, is the product line — branded, authenticated caller identity rendered on the handset. Everything since has been console and self-service work: RCS test-number management, Voice API debug logs surfaced in Voice Insights, port-in FOC changes and cancellations up to ten minutes before the port, MOS scores in the app, and now 10DLC campaign registration moving out of API-only access into the Bandwidth App alongside brand sharing across accounts.

What is grommunio?

grommunio's feed publishes release pointers only; the changes themselves live on GitHub.

The crawled feed carries twelve release-note stubs spanning August 2021 to June 2026, each the same 134-character sentence directing readers to GitHub for the detailed logs. Version 2026.06.1 is the most recent. Nothing in the feed states what changed in any release, so the platform's current capability surface cannot be read from this source.

Bandwidth vs grommunio: editorial side-by-side

B6.3

Bandwidth sells trust in the call, and self-service everywhere it used to sell tickets.

◆ Current state

The release stream splits cleanly in two: one entry that adds a product line and a run of entries that remove reasons to open a support ticket. Identity Presentation, in beta since mid-August, is the product line — branded, authenticated caller identity rendered on the handset. Everything since has been console and self-service work: RCS test-number management, Voice API debug logs surfaced in Voice Insights, port-in FOC changes and cancellations up to ten minutes before the port, MOS scores in the app, and now 10DLC campaign registration moving out of API-only access into the Bandwidth App alongside brand sharing across accounts.

◆ Where it's heading

The registration surfaces are converging on a single console. 10DLC and RCS both have Registration Centers, both reached the app within a week of each other, and both took the same API-first, UI-second order — integrators served first, operators after. The reseller item is the more consequential half of this release: sharing brands natively across accounts treats the multi-account hierarchy as a first-class structure rather than something customers duplicate records to work around, which matters for the wholesale and reseller business that carrier-adjacent vendors depend on.

◆ Prediction

Expect the remaining registration and porting workflows to follow the same API-then-UI path into the Bandwidth App, and the RCS Registration Center to pick up the cross-account brand sharing that 10DLC just received. Whether Identity Presentation leaves beta is the open question these entries do not answer.

G0.0

grommunio's feed publishes release pointers only; the changes themselves live on GitHub.

◆ Current state

The crawled feed carries twelve release-note stubs spanning August 2021 to June 2026, each the same 134-character sentence directing readers to GitHub for the detailed logs. Version 2026.06.1 is the most recent. Nothing in the feed states what changed in any release, so the platform's current capability surface cannot be read from this source.

◆ Where it's heading

The only signal available is cadence, and it is thin and irregular: twelve published notes across roughly five years, with 2023.11.x, 2025.01.x and 2026.06.1 as the visible markers. That is a release-notes page maintained as an index rather than a changelog. Reading direction from grommunio would require the GitHub logs these notes point at.

◆ Prediction

Expect the next entry to be another dated pointer of the same form. Whether grommunio's real release cadence matches this feed cannot be determined from what is published here.
