There will be no further updates to the online Code Snippets Database for users of all current versions of CodeSnip (i.e. up to v4.15.1)
There is a new GitHub repo containing a version of the online database. This has been done so the the database will not be lost after DelphiDabbler.com closes down on 15 June 2020. The database is being reformatted. The only change to content is that the two String Management categories have been merged.
The new release of CodeSnip I'm working on will be able to import the reformatted database, although it will have to be downloaded manually and imported from file.
Note that although all current versions of CodeSnip 4 will allow you to submit new code to the database (at least until DelphiDabbler.com closes), such submissions are no longer being accepted.
