links was updated to 2.17:

* Fix verifying SSL certificates for numeric IPv6 addresses
* Delete the option -ftp.fast - it doesn't always work and ftp performance is not an issue anymore
* Add bold and monospaced Turkish letter 'i' without a dot
* On OS/2 allocate OpenSSL memory fro the lower heap. It fixes SSL on systems with old 16-bit TCP/IP stack
* Fix IPv6 on OpenVMS Alpha
* Support mouse scroll wheel in textarea
* Delete the option -http-bugs.bug-302-redirect - RFC7231 allows the "buggy" behavior and defines new codes 307 and 308 that retain the post data
* X11 - fixed colormap leak when creating a new window
* Fixed an infinite loop that happened in graphics mode if the user clicked on OK in "Miscellaneous options" dialog and more than one windows were open. This bug was introduced in Links 2.15
* Support 6x6x6 RGB palette in 256-bit color mode on framebuffer
* Implement dithering properly on OS/2 in 15-bit and 16-bit color mode. In 8-bit mode, Links may optionally use a private palette - it improves visual quality of Links images, but degrades visual quality of other concurrently running programs.
* Improve scrolling smoothness when the user drags the whole document
* On OS/2, allocate large memory blocks directly (not with malloc). It reduces memory waste
* Fixed a bug that setting terminal title and resizing a terminal didn't work on OS/2 and Windows. The bug was introduced in Links 2.16 when shutting up coverity warnings
* Set link color to yellow by default
* Delete the option -http-bugs.bug-post-no-keepalive. It was needed in 1999 to avoid some bug in some http server and it is not needed anymore
* Trust Content-Length on HTTP/1.0 redirect requests. This fixes hangs with misbehaving servers that honor Connection:keep-alive but send out HTTP/1.0 reply without Connection: keep-alive. Links thought that they don't support keep-alive and waited for the connection to close (for example http://www.raspberrypi.org)
* Use keys 'H' and 'L' to select the top and bottom link on the current page

links was updated to 2.16:

* Improve handling of the DELETE key
* Implement the bracketed paste mode
* Fix various bugs found by coverity
* Fix a crash in proxy authentication code
* Fixed internal error "invalid set_handlers call" on framebuffer if links is suspend and terminate at the same time
