These are sometimes +malicious and sometimes accidental, but the effect on users is the +same. + +The changes here improve query compilation in several respects in order +to reduce the chances of an overly complex query causing problems for +the search subsystem. + +More work is done up front to simplify and combine parts of the +resulting SQL, allowing more work to be done closer to the data. +This change allows Evergreen to handle many more tested or chained +boolean expressions, and negated terms are now handled directly in +line with other adjacent terms. Phrases (exact matches) are now +searched for using Postgres' adjacency tsearch operator. + +All of these changes work together to improve performance by getting +more search work done in fewer database operations while protecting +against certain query constructs that have caused problems in the +past. + +This is https://bugs.launchpad.net/evergreen/+bug/1775958[Bug 1775958]. + +=== Restrict login redirect === + +As a security best-practice, Evergreen should not allow arbitrary +redirection on successful login, but instead limit redirection to +local links or configured domains and schemes. + +This feature is controlled by a new global flag called *opac.login_redirect_domains* +which must contain a comma-separated list of domains. All hostnames +under each domain is allowed for redirect, and the scheme of the +redirect URL must be one of http, https, ftp, or ftps. + +This is https://bugs.launchpad.net/evergreen/+bug/1908576[Bug 1908576]. + ==== Accessibility ==== * Fixes duplicate ID in staff catalog bib actions (https://bugs.launchpad.net/evergreen/+bug/2016341[Bug 2016341]) @@ -34,7 +82,7 @@ This release contains bug fixes improving on Evergreen 3.9.2. -==== Catalog ==== +==== Catalog ==== * Adds consistency to SMS Carrier dropdown display (https://bugs.launchpad.net/evergreen/+bug/1889916[Bug 1889916]) -- 1.7.2.5
