0.25

Since 19th July, 2025 (beta1 in 0.25.0-beta1, 13th July, 2025)

After reading Issue #668, I conducted another self-review of the E2EE-related code. In retrospect, it was clearly written by someone inexperienced, which is understandable, but it is still rather embarrassing. Three years is certainly enough time for growth.

I have now rewritten the E2EE code to be more robust and easier to understand. It is significantly more readable and should be easier to maintain in the future. The performance issue, previously considered a concern, has been addressed by introducing a master key and deriving keys using HKDF. This approach is both fast and robust, and it provides protection against rainbow table attacks. (In addition, this implementation has been a dedicated package on the npm registry, and tested in 100% branch-coverage).

As a result, this is the first time in a while that forward compatibility has been broken. We have also taken the opportunity to change all metadata to use encryption rather than obfuscation. Furthermore, the Dynamic Iteration Count setting is now redundant and has been moved to the Patches pane in the settings. Thanks to Rabin-Karp, the eden setting is also no longer necessary and has been relocated accordingly. Therefore, v0.25.0 represents a legitimate and correct evolution.

0.25.21.beta2

8th October, 2025

Fixed

• Fixed wrong event type bindings (which caused some events not to be handled correctly).
• Fixed detected a timing issue in StorageEventManager
  • When multiple events for the same file are fired in quick succession, metadata has been kept older information. This induces unexpected wrong notifications and write prevention.

0.25.21.beta1

6th October, 2025

Refactored

• Event handling now does not rely on 'convention over configuration'.
  • Services.ts now have a proper event handler registration system.

0.25.20

26th September, 2025

Fixed

• Chunk fetching no longer reports errors when the fetched chunk could not be saved (#710).
  • Just using the fetched chunk temporarily.
• Chunk fetching reports errors when the fetched chunk is surely corrupted (#710, #712).
• It no longer detects files that the plug-in has modified.
  • It may reduce unnecessary file comparisons and unexpected file states.

Improved

• Now checking the remote database configuration respecting the CouchDB version (#714).

0.25.19

18th September, 2025

Improved

• Now encoding/decoding for chunk data and encryption/decryption are performed in native functions (if they were available).
  • This uses Uint8Array.fromBase64 and Uint8Array.toBase64, which are natively available in iOS 18.2+ and Android with Chrome 140+.
    • In Android, WebView is by default updated with Chrome, so it should be available in most cases.
  • Note that this is not available in Desktop yet (due to being based on Electron). We are staying tuned for future updates.
  • This realised by an external(?) package octagonal-wheels. Therefore, this update only updates the dependency.

0.25.18

17th September, 2025

Fixed

• Property encryption detection now works correctly (On Self-hosted LiveSync, it was not broken, but as a library, it was not working correctly).
• Initialising the chunk splitter is now surely performed.
• DirectFileManipulator now works fine (as a library)
  • Old DirectFileManipulatorV1 is now removed.

Refactored

• Removed some unnecessary intermediate files.

0.25.17

16th September, 2025

Fixed

• No longer information-level logs have produced during toggling Show only notifications in the settings (#708).
• Ignoring filters for Hidden file sync now works correctly (#709).

Refactored

• Removed some unnecessary intermediate files.

0.25.16

4th September, 2025

Improved

• Improved connectivity for P2P connections
• The connection to the signalling server can now be disconnected while in the background or when explicitly disconnected.
  • These features use a patch that has not been incorporated upstream.
  • This patch is available at vrtmrz/trystero.

0.25.15

3rd September, 2025

Improved

• Now we can configure forcePathStyle for bucket synchronisation (#707).

0.25.14

2nd September, 2025

Fixed

• Opening IndexedDB handling has been ensured.
• Migration check of corrupted files detection has been fixed.
  • Now informs us about conflicted files as non-recoverable, but noted so.
  • No longer errors on not-found files.
