Desktop email client Thunderbird announced a move to monthly releases by default earlier this year, allowing new users to benefit from new features, sooner – as the new Thunderbird 136.0 release makes evident!

Thunderbird 136.0 sees messages auto-adapt to dark mode (and adds a quick toggle to control this in the header) — no more searing-white e-mail shocks in dark rooms!

Also added is a new Appearance setting to control message threading and sorting order globally. This is great if you always want, say, new messages at the bottom in all your configured folders.

Some notable fixes include ensuring that addresses clicked in the header no longer appear off-screen for those using HiDPI displays, and ensuring that UI font sizes changes made in app do apply to all areas (as a few dialogs weren’t hooked in).

Other changes, tweaks, UI improvements, and performance buffs feature (some issues may related to the previous release channel release and might not have been presented in ESR builds) including:

Beyond that, there’s a fresh round of security patches to plug newly discovered and/or recently disclosed flaws (and some of those will make their way to Thunderbird ESR channel users too).
