  Kodaikanal Solar Observatory (KoSO) possesses one of world's longest and
homogeneous records of sunspot observations that span more than a century
(1904-2017). Interestingly, these observations (originally recorded in
photographic plates/films) were taken with the same setup over this entire time
period which makes this data unique and best suitable for long-term solar
variability studies. A large part of this data, between 1921-2011, were
digitized earlier and a catalog containing the detected sunspot parameters
(e.g., area and location) was published in Mandal et al.(2017). In this
article, we extend the earlier catalog by including new sets of data between
1904-1921 and 2011-2017. To this end, we digitize and calibrate these new
datasets which include resolving the issue of random image orientation. We fix
this by comparing the KoSO images with co-temporal data from Royal Greenwich
Observatory. Following that, a semi-automated sunspot detection and automated
umbra detection algorithm are implemented onto these calibrated images to
detect sunspots and umbra. Additionally, during this catalog updation, we also
filled data gaps in the existing KoSO sunspot catalog (1921-2011) by virtue of
re-calibrating the 'rouge' plates. This updated sunspot area series covering
nearly 115 years (1904-2017) are being made available to the community and will
be a unique source to study the long term variability of the Sun
