2023-03-08
Vely release notes for 16.6.0
- Minor: added dynamic boolean expression support for previously static true/false flags in the following statements: count-substring, decrypt/encrypt-data, derive-key, hash-string, match-regex, out-header, send-file, read-hash, set-cookie, delete-cookie, write-file. This change allows for less code that is easier to read. Each flag that is enhanced signifies a static choice (such as download in send-file); now however, each such flag will also have an optional boolean expression that allows run-time selection.
- Minor: added secure clause in delete-cookie since newer changes in popular browsers require this option when deleting a secure cookie.

2022-11-29
Vely release notes for 14.2.0
- Minor: simplified URLs to access applications. Path-based URLs are now the default form of URL. This means a URL path in form of /app-path/request-name followed by optional REST-style parameters and a query string. This kind of URL is easier to read and write, general-purpose, and flexible for both REST and non-REST usage. The existing normalized URL will still be available.
- Minor: examples updated with new URL defaults; old ones still work the same to ensure backward compatibility.
- Release: documentation on URL structure and URL building simplified and a number of erratas fixed.
