2019. Slack speeded up its group chat for Windows and Web


Slack is launching a major update to its web and desktop today that doesn’t introduce any new features or a new user interface. Instead, it’s almost a complete rebuild of the underlying technology.Slack promises that this new version will use up to 50 percent less memory than before and that Slack will load 33 percent faster. Joining an incoming call will also be ten times faster now. A lot of these changes will be especially apparent to users who are part of multiple workspaces. That’s because the developers designed the new architecture with the assumption that many users are now part of multiple workspaces. Those used to take up a lot of memory and CPU cycles when you switched between them, as each workspace used to get its own Electron process in the old app.




2019. Slack integrates with email



Slack's latest feature allows users to message coworkers via email. The feature, which will be rolling out over the next couple months, is meant to give people who don't use Slack a way to keep up with conversations their coworkers are having inside the messaging app. When they’re mentioned by username in channels or sent a direct message, Slack will route those messages into their email inbox so they don’t miss out on important information while they’re getting themselves set up. Initially, the Slack to email messages will only be one-way, meaning the recipient can view the conversation from their inbox but won't be able to respond directly. But Slack says it will eventually allow people to messages via email as well.


2018. Slack acquires email assistant Astrobot



Slack has acquired Astro, the startup behind email assistant, Astrobot. The deal, which marks Slack’s largest to date, will go a ways toward helping the popular enterprise chat platform achieve its vision of fully integrating workplace mainstays like email and calendars into its channels. Astrobot is a Slack app that integrates email and calendars directly into the chat platform. Among other things, it lets users search both at once, without leaving Slack. The standalone Mac, iOS, Android, Amazon Alexa, and Slack apps will be shut down on October, with signups for new users being disabled immediately.


2018. Slack is buying, and shutting down HipChat and Stride



Slack is buying, and shutting down Atlassian's workplace group chats HipChat and Stride (that are Slack's competitors). Both tools will be discontinued and users - migrated to Slack. Hipchat was launched in beta form back in 2009, long before Slack’s debut in 2013. It mostly ruled its space in the time in between, leading Atlassian to acquire it in March of 2012. Slack quickly outgrew it in popularity though for myriad reasons — be it a bigger suite of third-party integrations, a better reputation for uptime, or better marketing. By September of 2017, Atlassian overhauled its chat platform and rebranded it as as “Stride”, but it was never able to quite catch up with Slack’s momentum.


2018. Slack acquired routine automation app Missions



Slack has acquired Missions, the app that allows Slack users to build tools to automate simple routines without code. Missions’ technology lets people create workflows for tasks that they might normally have to talk about inside Slack and then carry out the process off-chat. With Missions, Slack hopes that users can help teams boost productivity by making things more simple for a variety of repeatable processes. Other potential areas for the app to help users include managing approvals and rejections in the hiring process, as well as internal ticketing.
