## 2026-03-17 - 4.8.17 - fix(protocol)
|
||||||
|
increase per-stream flow control windows and remove adaptive read caps
|
||||||
|
|
||||||
|
- Raise the initial per-stream window from 4MB to 16MB and expand the adaptive window budget to 800MB with a 4MB floor
|
||||||
|
- Stop limiting edge and hub reads by the adaptive per-stream target window, keeping reads capped only by the current window and 32KB chunk size
|
||||||
|
- Update protocol tests to match the new adaptive window scaling and budget boundaries
|
||||||
|
|
||||||
|
## 2026-03-17 - 4.8.16 - fix(release)
|
||||||
|
bump package version to 4.8.15
|
||||||
|
|
||||||
|
- Updates the package.json version field from 4.8.13 to 4.8.15.
|
||||||
|
|
||||||
|
## 2026-03-17 - 4.8.13 - fix(remoteingress-protocol)
|
||||||
|
require a flush after each written frame to bound TLS buffer growth
|
||||||
|
|
||||||
|
- Remove the unflushed byte threshold and stop queueing additional writes while a flush is pending
|
||||||
|
- Simplify write and flush error logging after dropping unflushed byte tracking
|
||||||
|
- Update tunnel I/O comments to reflect the stricter flush behavior that avoids OOM and connection resets
|
||||||
|
|
||||||
## 2026-03-17 - 4.8.12 - fix(tunnel)
|
## 2026-03-17 - 4.8.12 - fix(tunnel)
