                    KNOWN ISSUES:
                    \nNo known issues. This does not mean that version is flawless. There can still be issues that are not identified. It is still beta.<\/p>\n

                    NEW VERSION FAQ:<\/strong><\/p>\n

                    Q1. Do the new data plugins load as part of the update or do they need to be updated separately ?<\/strong>
                    \nA1. New plugins are part of the update. You don't need to install them seprately.<\/p>\n

                    Q2. Do existing 3rd party DLLs work with new version?<\/strong>
                    \nA2. Existing 3rd party DLLs continue to work OK<\/strong>, thanks to backward compatibility layer added in 5.27, but
                    \na) compatibility layer induces some extra CPU overhead (less than 0.001 sec per 1000 bars retrieved from data plugin)
                    \nb) of course new features (extended resolution and floating point volume) are not available using old plugins
                    \nAlso, the change only affects DATA plugins. Any other plugins (AFL, optimizer) do not require any change.<\/p>\n

                    Q3. Will new version read my old database structure ?<\/strong>
                    \nA3. Yes. AmiBroker 5.27.0 alpha \/ 5.28 \/ 5.29 BETA will load your old databases without problems and all your watch lists, drawings, groups, etc are preserved. What is different, is that new version, once it saves the data, will save it in NEW format that is only readable with v5.27 and above. <\/p>\n","protected":false},"excerpt":{"rendered":"
