Just released VectorMind! My Sunday project turned into a simple REST API + MCP server for embeddings & vector search using Redis + @docker.com Agentic Compose.

Perfect for local AI agents. Dead simple to use.

curl 8.17.0
Download curl from curl.se. ## Release presentation As per tradition, there will be a live-streamed release presentation on twitch at 09:00 UTC (10:00 CET) on the release day. Available on YouTube after the fact. ## Numbers the 271st release 11 changes 56 days (total: 10,092) 448 bugfixes (total: 12,537) 699 commits (total: 36,725) 2 new public libcurl function (total: 100) 0 new curl_easy_setopt() option (total: 308) 1 new curl command line option (total: 273) 69 contributors, 35 new (total: 3,534) 22 authors, 5 new (total: 1,415) 1 security fixes (total: 170) ## Security CVE-2025-10966: missing SFTP host verification with wolfSSH. curl’s code for managing SSH connections when SFTP was done using the wolfSSH powered backend was flawed and missed host verification mechanisms. ## Changes We drop support for several things this time around: * drop Heimdal support * drop the winbuild build system * drop support for Kerberos FTP * drop support for wolfSSH And then we did some other smaller changes: * up the minimum libssh2 requirement to 1.9.0 * add a notifications API to the multi interface * expand to use 6 characters per size in the progress meter * support Apple SecTrust – use the native CA store * add `--knownhosts` to the command line tool * wcurl: import v2025.11.04 * write-out: make `%header{}` able to output _all_ occurrences of a header ## Bugfixes We set a new project record this time with no less than 448 documented bugfixes since the previous release. The release presentation mentioned above discusses some of the perhaps most significant ones. ## Coming next There a small set of pull-requests waiting to get merged, but other than that our future is not set and we greatly appreciate your feedback, submitted issues and provided pull-requests to guide us. If this release happens to include an annoying regression, there might be a patch release already next week. If we are lucky and it doesn’t, then we aim for a 8.18.0 release in the early January 2026.

N’en déplaise à ceux qui pensent que Kubernetes ne sert à rien, 10 ans après le premier commit, cet outil est devenu un standard de-facto. Il permet à de nombreuses équipes tech de gérer de manière efficace des logiciels hétérogènes, tout en apportant aux développeurs l’autonomie qu’ils souhaitaient
