> # Archive Engine Version Info

> Version | Detail
> --- | ---
> 3.0.1 - 2011/06/13 | Pluggable config and write support.
> 3.0.0 - 2011/06/06 | Built on CSS 3.0.0.
> 1.2.4 - 2011/01/27 | Fix bug that caused exception when 'stopping' or 'restarting' while already restarting.
> 1.2.3 - 2010/07/08 | Oracle SQL without 'APPEND' hint to avoid locking.
> 1.2.2 - 2010/06/28 | Added timeout preference (30 min) to sample table access.
> 1.2.1 - 2010/06/15 | Slight optimization of startup.
> 1.2.0 - 2010/03/18 | New 'Delta' sample mode: Channel configuration includes sample mode 'value'. Monitored channels use sample values greater than zero as 'delta', storing only received samples that differ from the previously archived sample by that delta. Display of 'current' value was wrong.
> 1.0.8 - 2010/02/22 | Show 'Write Error' state in http "/main"
> 1.0.7 - 2009/12/21 | Count received values
> 1.0.6 - 2009/09/04 | Throttle 'back-in-time' messages
> 1.0.5 - 2009/08/26 | Main loop error dumps stack trace
> 1.0.4 - 2009/08/07 | PV layer fix to support PV type changes on IOC reboots
> 1.0.3 - 2009/07/08 | 'Monitored' mode no longer complains about initial back-in-time 'Scan' mode fixes: No more duplicates after 'restart'; store most recent original sample instead of host time stamp Suppress samples that are too far into the future (clock of host or IOC must be wrong) Eclipse 3.5 'debug' URL PV layer supports simulated PVs
> 1.0.2 - 2009/06/16 | On batch error, try individual inserts. Simpler back-in-time code Limit length of string samples (1.0.2d)
> 1.0.1 - 2009/06/11 | HTTPD shows version detail, period estimate for monitored channels, lists disconnected channels. Minimum sample period (1.0 secs)
> 1.0.0 - 2009/05/20 | Consistently set this version info as printed on startup, defined in EngineModel.VERSION, and also matches the version of the org.csstudio.archive.engine plug-in. Before this date, those showed different numbers.
