Release notes for Gerrit 2.9.3

WARNING: There are no schema changes from 2.9.2, but when upgrading from an existing site that was initialized with Gerrit version 2.6 to version 2.9.1 the primary key column order will be updated for some tables. It is therefore important to upgrade the site with the init program, rather than only copying the .war file over the existing one.

It is recommended to run the init program in interactive mode. Warnings will be suppressed in batch mode.

WARNING: When upgrading from version 2.8.4 or older with a site that uses Bouncy Castle Crypto, new versions of the libraries will be downloaded. The old libraries should be manually removed from site’s lib folder to prevent the startup failure described in Issue 3084.

It turned out that SSHD 0.13.0 still suffers from this issue, which causes problems for users of the stream-events in Gerrit 2.9.2.

SSHD 0.9.0 is known to be free from this particular issue, but we cannot downgrade to that version because it includes some other known issues:

SSHD version 0.9.0-4-g5967cfd is based on 0.9.0 and includes fixes for SSHD-254 and SSHD-330.

Due to the downgrade of SSHD, the following libraries are also downgraded:
