17 April 2013: The April version (2013.04) of the CPC scheme is now available.
No revisions (leading to the creation or deletion of symbols) were implemented
since the last (2013.01) version.
However, a first large number of automatic corrections were executed. Most of the subclasses were impacted.
More precisely, about 600 corrupted Notes and Warnings were regenerated, almost 700 references containing ECLA symbols were updated, more than 5000 missing class and subclass hyperlinks were introduced and the remaining ECLA version indicators were removed.
The April version (2013.04) of the CPC scheme is now also available in a new presentation, so called "interleaved presentation". In the "interleaved presentation" the breakdown codes come interleaved with the main trunk symbols. This presentation can be accessed via the table (≡ next to the scheme gives access to the corresponding interleaved version). More information here.
