What is Apprise?

The final v1.x release slipped by one patch, but the v2 deadline stands.

Apprise is a Python notification library that fans a single call out to more than 150 services. Weighted tagging in v1.11 turned that fan-out into ordered delivery with fallback, and the releases since have been service accretion and bug clearance. v1.13.0 was announced as the last of the v1.x line; v1.13.1 has now shipped anyway, adding Signalgrid and Lauther support and fixing a memory-backed attachment failure, with the maintainer repeating the end-of-line notice and adding that he means it this time.

What is Delta Chat?

Delta Chat patches a Team Profile regression and moves its Tauri build out of the repo.

The desktop client runs on a roughly weekly cadence. 2.59.0 added reactions on channel posts, a hideable window menu bar and experimental Team Profiles; 2.59.1 followed eight days later to fix messages staying unread when read from another device, a regression affecting profiles created with Team Profile enabled. The same patch adds Arabic, Telugu and Slovenian, and moves the Tauri edition to its own repository.

Apprise vs Delta Chat: editorial side-by-side

A
Apprise
COMMS
6.3

The final v1.x release slipped by one patch, but the v2 deadline stands.

◆ Current state

Apprise is a Python notification library that fans a single call out to more than 150 services. Weighted tagging in v1.11 turned that fan-out into ordered delivery with fallback, and the releases since have been service accretion and bug clearance. v1.13.0 was announced as the last of the v1.x line; v1.13.1 has now shipped anyway, adding Signalgrid and Lauther support and fixing a memory-backed attachment failure, with the maintainer repeating the end-of-line notice and adding that he means it this time.

◆ Where it's heading

The v1 line is being closed out in patches rather than stopped cleanly, which is the normal shape of a maintainer-led project absorbing community pull requests faster than it can cut a major version. The ask to downstream projects has not changed — pin to >=1.0.0,<2.0.0 — and v1.x is stated to keep security support for a year or two after v2 lands. What v2 actually breaks is still not described in any of these entries.

◆ Prediction

The next release is likely another v1.x patch of the same shape — community service plugins plus attachment and protocol fixes — unless a v2 alpha appears first. Nothing in these entries indicates which.

D5.0

Delta Chat patches a Team Profile regression and moves its Tauri build out of the repo.

◆ Current state

The desktop client runs on a roughly weekly cadence. 2.59.0 added reactions on channel posts, a hideable window menu bar and experimental Team Profiles; 2.59.1 followed eight days later to fix messages staying unread when read from another device, a regression affecting profiles created with Team Profile enabled. The same patch adds Arabic, Telugu and Slovenian, and moves the Tauri edition to its own repository.

◆ Where it's heading

The client is in a broadening phase - channel reactions, Team Profiles as an opt-in experiment, and continued keyboard and accessibility work carried forward from 2.53.0. Splitting out the Tauri edition indicates the Electron build remains the one that ships while the alternative develops at its own pace instead of gating releases. Language coverage keeps widening, which for this project is as much a distribution decision as a localisation one.

◆ Prediction

The 2.59.1 notes promise a more elaborate fix for the Team Profile unread bug in the coming weeks, so expect that in the next minor rather than another patch.
