1.6.1 - 2020-08-12

1.6.1 is not a required update, but adds some reliability improvements and checks to ensure correct operation.

- A sanity check for certificate expiry has been added. If a client does not successfully refresh the certificate for whatever reason, it will now shut down gracefully 24 hours before the certificate actually expires instead of failing silently.

- If the system time is off by more than 24 hours, a warning advising you to correct it will now be printed regularly. Failure to do so might make the certificate check trigger prematurely or fail to trigger at all.

- During proxy requests, when a file is requested but not found in cache, the backend will now provide an alternative source link in addition to the primary one. If the client is unable to connect to the primary source, it will automatically fall back to the secondary one.

- H@H now makes a best-effort attempt to include filesystem overhead for slack space in its cache size calculations. By default this calculation assumes a filesystem block size of 4kB which is by far the most common, adding an estimated overhead of 2 GB per 1 million files - roughly 0.5% for your average H@H cache.

Note that if your cache was at ~100%, this means it will be slighly over and prune this amount from the cache at the next startup. If you already left some extra space, you can increase the H@H cache by this amount BEFORE starting up to compensate. If you abort startup after seeing the pruning message, it will have to rescan the cache at next startup.

This does not reduce the amount of static ranges you can store at a given setting; it just adds 2kB (or blocksize/2) average overhead per file for the internal resource tracking.

You can specify a different blocksize with --filesystem-blocksize=xxx or turn this off by using --filesystem-blocksize=0


1.6.0 - 2020-01-02

1.6.0 is considered a stable release, and is a required update for clients running versions prior to 1.5.4. This release only has minor changes compared to 1.5.4, which remains a supported version and will not require an upgrade.

Compared to 1.4.2, this incorporates all changes in the 1.5 experimental branch. You can find those release notes here.

- When refreshing HTTPS certs, the client will now wait longer (up to five minutes) before it attempts starting the server back up if the listening thread takes unexpectedly long to terminate.

- When handling file requests, cache misses did not count towards the "total files sent" stat. (This only affected the readout in the GUI, server-side stats are not calculated by the clients.)


To update an existing client: shut it down, download Hentai@Home 1.6.1, extract the archive, copy the jar files over the existing ones, then restart the client.
