Frappe Framework vs Undertow: at a glance
What is Frappe Framework?
Two trains ship the same features minutes apart while v16 absorbs the CRM stack.
v15 and v16 now release in lockstep: v15.118.0 and v16.31.0 went out the same minute carrying the same two features, a between filter for numbers and dates and an activity timeline that records edits, milestones, and sharing events. What separates them is what only v16 receives — a Recorder timeline for document lifecycle, a grouped settings dialog, Cloud Settings in Desk. Both trains carry the same breaking export change, where CSV and Excel now show linked-record titles instead of internal names.
What is Undertow?
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
Undertow's 2.4 line opened in May 2026 with a release that combines three CVE fixes with a backlog of feature requests, several of them years old judging by their issue numbers — in-flight request processing time tracking, comments in the predicate language, a configurable async context timeout replacing a hard-coded one, HTTP/2 GOAWAY connection management, a TLS protocol version exchange attribute, and a method to invalidate all cache paths. The two releases since have been small: a handful of Jiras in 2.4.1, and a 2.4.2 whose entire release note is the sentence that it was tagged.

Frappe Framework
5.0DEVOPS
Two trains ship the same features minutes apart while v16 absorbs the CRM stack.
◆ Current state
v15 and v16 now release in lockstep: v15.118.0 and v16.31.0 went out the same minute carrying the same two features, a between filter for numbers and dates and an activity timeline that records edits, milestones, and sharing events. What separates them is what only v16 receives — a Recorder timeline for document lifecycle, a grouped settings dialog, Cloud Settings in Desk. Both trains carry the same breaking export change, where CSV and Excel now show linked-record titles instead of internal names.
◆ Where it's heading
v15 is being held at parity on features that are cheap to backport while v16 takes everything structural. The clearest case is the shared CRM and Helpdesk layer — forms, phone number fields, notifications, activity history — being folded into the framework so those apps stop carrying their own copies. Running underneath both is steady permission work: access checks on linked-record lookups, Report scripts restricted to approved methods, server-side Google sign-in, one-time codes for linked accounts.
◆ Prediction
Expect v16 minors to keep pulling app-level features into the framework while v15 receives only the small portable ones; the divergence between the two Features sections is already the reliable tell.
Undertow
0.0DEVOPS
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
◆ Current state
Undertow's 2.4 line opened in May 2026 with a release that combines three CVE fixes with a backlog of feature requests, several of them years old judging by their issue numbers — in-flight request processing time tracking, comments in the predicate language, a configurable async context timeout replacing a hard-coded one, HTTP/2 GOAWAY connection management, a TLS protocol version exchange attribute, and a method to invalidate all cache paths. The two releases since have been small: a handful of Jiras in 2.4.1, and a 2.4.2 whose entire release note is the sentence that it was tagged.
◆ Where it's heading
The 2.4.0 pattern — a long-deferred feature backlog shipping in the same release as security fixes — suggests features move when a release has to happen anyway rather than on their own schedule. What did ship points at operational control: timeouts that were hard-coded becoming configurable, connection lifecycle handling for HTTP/2, and attributes exposing TLS and timing detail to whatever sits above the server. Enabling test runs on JDK 25 in 2.4.1 is the only forward-looking item in the two follow-up releases.
◆ Prediction
With three entries and one substantive release among them, there is little to extrapolate from; the JDK 25 test enablement is the one thread that implies more work, pointing at runtime compatibility rather than features as the near-term focus.
