Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Brosix and SlickText — release velocity, themes, recent moves, and the top alternatives to consider.
Brosix 6.0 redesigns the 20-year-old messenger and upgrades calls and search.
Brosix is a 20-year-old team messenger. Version 6.0 brings a redesigned interface, clearer calls, better search and more consistent behaviour across desktop and mobile. It follows private channels and communities for clients and partners in April and audio and video calling in the mobile apps in May.
SlickText's feed is all SMS buying guides; no product release has surfaced since RCS.
SlickText's recent feed is entirely search content: SMS segmentation, church and nonprofit texting comparisons, Black Friday tactics, cost breakdowns and guides on annual plans. No release appears in the entries since the basic RCS addition.

It follows private channels and communities for clients and partners in April and audio and video calling in the mobile apps in May.
After a summer of referral campaigns and how-to posts, Brosix has shipped its largest release in years, modernising the client rather than changing what the product does. The April communities launch remains the one move that widened its scope beyond internal team chat.
Expect 6.0 follow-up posts and fixes as users move to the new client; the entries do not show a further change of direction.

The content is getting more explicit about buying decisions. Vertical comparison pages, published prices and an outgrown-your-platform pitch all aim at people ready to switch. Product motion cannot be read from these posts.
Expect Black Friday content through November and more vertical comparison pages. These entries give no evidence of how RCS is progressing.
