Download Oplon Client

Core

• added

  • the client no longer needs administrator rights on Windows: all privileged network operations are performed by a new background component, the Oplon Agent, installed and started by the installer. One authorization at install time, none afterwards
  • Settings page with preferences saved per user and restored on the next launch: launch at startup (Windows, macOS and Linux), dark mode, application version and one-click access to the log file
  • feature availability is checked at startup and shown in the interface: when a feature cannot work on this machine (agent not installed, WinFsp missing, reduced installation), the corresponding tab explains why instead of failing silently
  • on Linux and macOS the client verifies at startup that it has the privileges it needs and shows a clear message if it does not

• changed

  • interface redesigned and aligned with the Oplon look and feel: new light/dark themes, consistent cards, badges, status colours and spacing across every tab
  • resource cards are cleaner — technical details moved into an Info popover, while status and countdown stay visible at a glance
  • more reliable startup: the backend no longer depends on a UI signal that could arrive too early, twice, or not at all

• fixed

  • the window no longer keeps stealing the focus when a resource reports errors repeatedly

Trusted Connections

• added

  • NAT connections (Trusted Network) are now a first-class mode alongside Local Proxy: the card shows the destinations reachable through the tunnel, and the two modes are clearly distinguished in the interface
  • live countdown on every connection: time left before the session expires (NAT) or before the availability window closes
  • the availability windows (schedule) of a resource are listed in the Info popover, with the equivalent in local time when the resource uses a different time zone

• fixed

  • connections that close on their own (session expiry, transport failure, agent stopped) are now reported in the interface; previously the tunnel died silently and still looked active
  • bulk connections no longer failed from the second resource onwards
  • NAT adapters are now listed correctly by the system network tools on Windows

Shared Folders

• added

  • now available on macOS as well (requires macFUSE or FUSE-T)
  • now available on Linux

• changed

  • reworked mounting engine: all shares are now served by a single background process driven through its control API, instead of one process per share
  • the local cache moved to the user cache folder, with one stable directory per share and automatic size and age limits, so it no longer grows indefinitely

• fixed

  • pending uploads are flushed and the volume unmounted cleanly instead of being terminated abruptly (typically hit by the "safe save" of Office applications)
  • errors returned by a share are attributed to the right share and reported once, instead of flooding the interface and the log
  • mount processes left behind by a previous run are cleaned up at startup

Installer

• added

  • Windows: installation without administrator rights is supported as a reduced mode — the client works, without NAT connections and with the legacy shared-folders mechanism
  • Linux: one build now produces AppImage, .deb and .rpm, with an optional GPG signature for every artifact
  • macOS: signed and notarized DMG for Apple Silicon
  • every artifact is published with its .sha256 checksum, generated after signing

• changed

  • client certificates are now looked up in the per-user configuration folder as well, which is the recommended place for a manual installation and the only one usable with the AppImage and on macOS
