GDB 13.1 released

You can also use https://ftp.gnu.org/gnu/gdb/

I switched to this for my software announcements a long time ago: GDB should do the same. Even better is https://ftp.gnu.org/gnu/gdb/?C=M;O=D so results are sorted by descending modification date (newest first).

FTP is dying for most use cases, yes. It isn't fundamentally flawed – plain FTP is insecure, but FTPS isn't, yet few people implemented it; using two separate ports (one for control, the other for data) is a problem, but there are solutions (e.g. with FTPS you can share the same port for both, if you use TLS session resumption). The whole "corrupting files by transmitting them in ASCII mode" business was just FTP clients with stupid defaults and nobody would change those stupid defaults, but nowadays the vast majority of FTP clients default to binary mode.

One area in which FTP is still the best option however – surviving mainframe and minicomputer systems (which are greatly diminished from their former glory, but still with us, and I'm sure at least some of them will still be here, even further diminished, in 20 years time). Most of those systems have file systems which support "record-oriented files", in which the filesystem is aware of and enforces the division of the file into records, either fixed length (with the record length defined at file creation time) or variable length (each record starts with a header giving its length, and sometimes also some flags). Examples of such systems include OpenVMS, non-Linux IBM mainframe operating systems (z/OS, z/VM, z/TPF and VSEn), IBM i (formerly AS/400), and most surviving non-IBM mainframe lines (Unisys, Fujitsu, Atos/Bull). If you want to transfer a record-oriented file from OpenVMS to z/OS, keeping the record boundaries intact – the FTP protocol can do that out of the box, HTTP(S) or SFTP don't support that.

Another area in which FTP seems to still be hanging on is scientific computing, where GridFTP is used to transfer massive data sets. GridFTP is a bunch of extensions defined to the classic FTP protocol. GridFTP is still actively used, although it has seemed to have fallen in popularity ever since its main backer (Globus) transitioned from being an open source project to a paid SaaS offering with proprietary clients. IBM Aspera performs much better (and isn't based on FTP at all), but costs a lot more $$$$.
