The two maps illustrate the main changes

The two maps illustrate the main changes which (that ) have taken place in the town of Kimsville between the year 2002 and today. In general, it can be seen that, despite remaining stable some facilities, Kimsville has become much more modern over a period in question.
Looking at the maps in more detail, one interesting change has been the introduction of a new train station in the West of the town. If we look at the North of the city, a shopping center and a green area with lots of trees, remained unchanged. By contrast (COMMA) there also used to be a green area to the West of the shopping center, but now it has been knocked down to make a way for new apartments(it was demolished to make room for the construction of new apartments).
Another striking change is that there would be a factory to the East of the city center in 2002, but it has been turned into a software company in recent years. Regarding the South of the town (Regarding the southern part of the town.), an old cinema and a woodland have also been converted into a pub and a football stadium accordingly (an old cinema and a woodland were converted into a pub and a football stadium, respectively), but the woodland situated in another side of the cinema stayed the same(remained unchanged).

"remained stable" in another words?

"stayed constant," "kept steady," "held steady," "maintained stability," "stayed the same."
