This release contains a few breaking changes that are described in the upgrade guide. The breaking changes are mostly a code and project reorganization that should be easy to upgrade to.

Besides the reorganization some notable changes are:

• The scheduled jobs system now has a watch dog that will reset any job that is stuck in a running state. Eg if the process crashed after the job finished but before Nexus was able to update the job status.
• All NuGet dependencies have been updated to the latest version as well as .NET.
• Serilog is no longer a dependency to Nexus.
• Newtonsoft.Json is no longer a direct dependency to Nexus, the support for Newtonsoft.Json has been extracted to a separate package.
• It's now possible to register middlewares around job execution.
• It's now possible to set job and log history per job.

1.23.0

• Allows queue jobs to set custom statuses for messages. Read more here.

1.22.0

• Adds message priority for queues. Read more here.

1.21.1

1.20.3

• Adds retries to the database maintenance job when using Postgres.

1.20.2

• Fixes risks for deadlocks when job progress hasn't finished writing before the job is done. When a job finishes and cleanup attempts to delete job progress before the job progress has finished writing a deadlock could occur because the update and cleanup/delete tries to write the same row.

1.20.1

• Removes a query hint when using SQL Server that required READ COMMITTED isolation level. The recommended isolation level is READ COMMITTED SNAPSHOT, but is not a hard requirement.

1.20.0

• Makes it possible to initiate a soft graceful shutdown which means that all jobs, functions, etc that has already started will run until finished but no new work will be started. See more here.

1.19.0

• Fixes regression around running internal Nexus migrations.

1.19.0

• Makes it possible to pass a transaction to DbConnectionScope.

1.14.0

1.13.1

• Fix issue which caused migrations to be run out-of-order

1.13.0

• Make it possible to use Nexus job logs in the admin UI without Serilog.

Previously you needed to use Serilog in order for your job logs to get the correct context/scope values attached to know which job they originated from. Nexus now uses standard .NET logging for this which means that you no longer need to use Serilog for it. See more in the documentation under Jobs / Logs.

1.12.1

• Reset healthchecks when an instance is starting. If an instance crashed or was deployed in the middle of when a healthcheck was running it can still be reported as running after the deploy or restart finishes. This fixes that all healthchecks are reset that claims to be running on the instance that is just starting up.

1.12.0

• Added JobResults.CompletedWithWarnings() which lets a job return a successful status but have the run flagged with a warning sign in the Admin UI and the job health check status become Degraded

1.11.0

• Messages that are scheduled for a retry now has a new status called AwaitingRetry instead of being in the Error status.
