v0.9

[alphapapa]

Compatibility

• The minimum supported Emacs version is now 27.1. (It is no longer practical to test plz with Emacs versions older than 27.1. For Emacs 26.3, an earlier version of plz may be used, or this version might be compatible, with or without minor changes, which the maintainer cannot offer support for.)

Changes

• Option plz-timeout is removed. (It was the default value for plz's :timeout argument, which is passed to Curl as its --max-time argument, limiting the total duration of a request operation. This argument should be unset by default, because larger or slower downloads might not finish within a certain duration, and it is surprising to the user to have this option set by default, potentially causing requests to timeout unnecessarily.)
• Using arguments :as 'file or :as '(file FILENAME) now passes the filename to Curl, allowing it to write the data to the file itself (rather than receiving the data into an Emacs buffer and then writing it to a file. This improves performance when downloading large files, significantly reducing Emacs's CPU and memory usage).

Fixes

• Improve workaround for Emacs's process sentinel-related issues. (Don't try to process response a second time if Emacs calls the sentinel after plz has returned for a synchronous request. See #53. Thanks to Joseph Turner for extensive help debugging, and to USHIN for sponsoring some of this work.)
• Inhibit buffer hooks when calling generate-new-buffer (as extra protection against "kill buffer?" prompts in case of errors). (See #52. Thanks to Michał Krzywkowski.)
  • Avoid "kill buffer?" prompts in case of errors on Emacs versions before 28. (See #52 and #57. Thanks to Michał Krzywkowski.)

Development

• plz is now automatically tested against Emacs versions 27.1, 27.2, 28.1, 28.2, 29.1, 29.2, 29.3, and a recent snapshot of the master branch (adding 29.2 and 29.3).
