OpenUaExplorer 1.0.0-rc1

The first release candidate. Everything planned for 1.0 is in — from here on it's bug fixes only.

Connections and security

Connecting to a secured server used to be the part where you gave up.

Passwords can be remembered per profile, stored in the OS keychain — never in the session file.
Certificate handling was reworked. The PKI manager derives the application URI from the client certificate, so mismatched-URI rejections — the most common and least explicable OPC UA failure — no longer happen silently.
Errors say what went wrong: a rejected user token, a rejected certificate and an unreachable endpoint are now told apart, and retry loops stop flooding the log with the same warning.
The connection dialog was redesigned — it no longer jumps around as you switch authentication modes.

Browsing is incremental. The tree fetches one node at a time and keeps going when a branch fails, so one refused node no longer stalls the rest — and large folders don't freeze the UI.
Much broader type formatting, driven by the node's DataType: timestamps render as dates instead of 64-bit integers, short arrays are summarised inline, and encoded images open in a viewer instead of a wall of hex.
The write dialog accepts hexadecimal byte input, which makes writing ByteStrings practical.
Data Access moved to a tree view, and closed pages can be restored — close a tab by accident and it comes back. Long text is elided with a tooltip carrying the full value.

Zoom and pan, with history re-read from the server for the visible range rather than reused from the buffer — so zooming out gives you real data, not a coarser version of what you already had.
Hover shows a value plaque tracking the series under the cursor, and live series extend without the gaps at the leading edge that beta 2 had.
Chartability is decided from DataType and ValueRank, so non-numeric nodes don't offer a trend that can't be drawn.

Optional debug logging with configurable depth; routine non-events demoted from warnings.
Sessions carry a schema version, so files written now stay readable as the format evolves.
Translations updated across German, Russian and Simplified Chinese, switchable live.
Third-party licences now ship with the application.
