# v0.4.0 — Performance & stability overhaul
|
|
|
|
## ✨ New features
|
|
|
|
**Terminal performance overhaul**
|
|
* Heavy output (long boot logs, big file dumps) now renders much more smoothly — drawing was
|
|
reworked to stop re-creating fonts and brushes on every frame.
|
|
* Scroll-back history storage was rebuilt so the terminal stays fast no matter how much output
|
|
has accumulated; previously it got slower and slower once the history buffer filled up.
|
|
|
|
**Full-screen apps (vim / htop) behave like a real terminal**
|
|
* The mouse wheel now scrolls inside full-screen tools like `vim` and `htop` instead of doing nothing.
|
|
* Tools that ask the terminal "where is the cursor?" now get an answer — fixes full-screen apps
|
|
that could hang on startup or draw at the wrong position.
|
|
|
|
**Connection status you can actually see**
|
|
* When an SSH connection drops or hits an error, a message now appears right in the tab —
|
|
no more sessions that silently stop responding.
|
|
* When the local shell exits (e.g. you type `exit`), the tab shows
|
|
`[ETTerms] shell process exited` instead of just going dead.
|
|
|
|
**Faster PDU status (GUI and AI)**
|
|
* Outlet polling now bundles all 12 ports into a few SNMP requests instead of 36 separate ones —
|
|
the Status page refreshes faster, and an unreachable PDU no longer stalls the poll for minutes.
|
|
* The AI `pdu_status` tool gets the same speed-up.
|
|
|
|
## 🐛 Bug fixes
|
|
|
|
**Garbled Chinese / non-English text**
|
|
* Fixed: multi-byte characters could occasionally turn into `�` garbage when text was split
|
|
across data chunks — this affected TTL script `wait` matching, what the AI reads over the
|
|
serial bridge, and saved session log files. All three now decode correctly.
|
|
|
|
**Scrolling**
|
|
* Fixed: while you were scrolled back reading history, any new output yanked the view down to
|
|
the bottom. The view now stays where you are and only follows when you're already at the bottom.
|
|
|
|
**Resource & stability**
|
|
* Fixed small memory and handle leaks when opening and closing many local shell tabs over a
|
|
long session.
|
|
* Fixed: typing into an SSH session after the connection died could crash the window — it now
|
|
just prints a short "write failed" note in the tab.
